**Can dogs eat cucumbers?** Yes, **dogs can eat cucumbers**. Just as it is for humans, cucumbers are a healthy, low-calorie treat that your [dog](https://howtodiscuss.com/t/why-do-dogs-lick-you/39514) will love. Cucumbers are especially good for dogs that need to lose weight, as their low-calorie content offers some rewards without the rolls. Cucumbers also have high water content. This crunchy vegetable is actually 96 percent water, which makes it a tasty and hydrating summer treat after a vigorous walk. Though the general rule is that, your dog should only be given [cucumber](https://howtodiscuss.com/t/types-of-salads/263) in moderation. ![](https://cdn.pixabay.com/photo/2019/08/19/07/37/french-bulldog-4415632__340.jpg) ## Is Cucumber Safe for Dogs to Eat? Cucumbers are perfectly safe for [dogs](https://howtodiscuss.com/t/can-dogs-see-color/39796) to eat, and offer a low-calorie, crunchy snack that many dogs love. Cucumbers only contain about 8 calories per one-half cup of slices, compared to the 40 calories in a single medium Milk-Bone biscuit, and are very low in sodium and fat. According to Dr. Karen Becker, 15-25% of a healthy dog’s diet should be fruits or vegetables, and a cucumber is a great option! They can even help keep your pet hydrated on hot summer days due to their high [water](https://howtodiscuss.com/t/how-many-ounces-in-a-gallon-of-water/40051) content. Your dog may find the satisfying crunch and juicy texture of a perfectly ripe cucumber just as thrilling as a biscuit or shop-bought treat, so cucumbers make a great, [healthy](https://howtodiscuss.com/t/health-is-wealth/28378) alternative for training treats, too. The crunchy cucumber also provides a moderate supply of [fiber](https://howtodiscuss.com/t/potato-nutrition/39850), making it excellent protection against gastrointestinal sluggishness. ## Is Cucumber Healthy for My Dog? Yes. Fresh cucumbers are about 96% [water](https://howtodiscuss.com/t/gallon-of-water-weight/38914) and are a delightfully crunchy way to stay hydrated on a hot day. They also contain vitamin C, vitamin K, potassium, and [magnesium](https://howtodiscuss.com/t/why-do-you-need-magnesium-supplements-and-how-much-you-should-eat/35939), all important components of a healthy canine [diet.](https://howtodiscuss.com/t/what-is-keto-diet/15595) However, pickled cucumbers (and other pickled veggies) are packed with salt and often contain other ingredients that are no-nos for dogs, such as [garlic](https://howtodiscuss.com/t/minced-garlic-to-clove/31231) or onion. So skip the pickles and stick to the fresh [veggies](https://howtodiscuss.com/t/can-dogs-eat-cauliflower/42173). ## Are there risks to feeding cucumbers to my dog? 1. There are very few risks that come with cucumbers. The [seeds](https://howtodiscuss.com/t/examples-of-dicots/38212) and skin are not toxic to your dog, but there are some precautions about how much you should offer them. 2. As with anything you offer your dog besides their daily diet, treats should only be 10% of their daily calories. This is also true for a fruit or vegetable low in [calories](https://howtodiscuss.com/t/how-many-calories-in-uranium/34049). 3. The dog food your [dog](https://howtodiscuss.com/t/can-dogs-have-apples/43571) eats has been scientifically proven to provide all their daily nutritional needs. Treats are just a supplement to a balanced diet. 4. Fresh cucumbers bought commercially can have added waxes to the skin. Be sure to wash this off with water to make it safer for your dog. 5. The high water and fiber content in cucumbers can cause gastrointestinal upsets like gas or [diarrhea](https://howtodiscuss.com/t/how-to-cure-upset-stomach/25229) if your dog eats too much. 6. If your dog has a sensitive [stomach](https://howtodiscuss.com/t/how-long-it-takes-to-digest-food/38335), you might see a tummy ache when your dog first tries cucumber or eats too much. 7. Dogs that have consumed [milk](https://howtodiscuss.com/t/can-dogs-drink-milk/41852) or dairy product before eating cucumber can also develop a tummy ache or stomach upset. 8. Most dogs don’t have any reaction or intolerance to this [tasty fruit](https://howtodiscuss.com/t/fruits-that-starts-with-r/34755), but whenever you offer your pup a new food, care should be taken to watch for any [allergic reactions](https://howtodiscuss.com/t/all-kinds-of-hypoallergenic-dog-breeds-to-keep-you-safe-and-happy/33062) like excessive itching, tummy upsets, vomiting, diarrhea, or rash. And we always recommend talking with your vet before you offer any new food. 9. Puppies are still developing their [immune systems](https://howtodiscuss.com/t/9-healthy-foods-to-improve-immunity-in-old-age/34043) and shouldn’t eat cucumber unless they are fully weaned and safely eating solid foods. To prevent your dog from choking, always cut food down to a manageable size. Feeding a whole cucumber is not advisable. They can be very susceptible to stomach upset, so go slowly with very small amounts at first. ## How many cucumbers Can My Dog Eat? A common recommendation from vets is to follow the 10% rule. Treats, including raw veggies, can make up 10% of the calories in your [dog’s diet](https://howtodiscuss.com/t/can-dogs-eat-cauliflower/42173). This might mean that you can treat your Papillon to a slender cucumber spear on a hot afternoon, while your [German shepherd](https://howtodiscuss.com/t/german-shepherd-golden-retriever-mix/39911) might get a big scoop of frozen cuke chunks. Fresh cucumbers are only about 1% sugar by weight, and one cup of chopped cucumbers has about 1 gram of sugar, 1 gram of dietary fiber, and 16 calories. This can make cucumbers a good treatment option for dogs on a reduced-calorie diet or with [diabetes](https://howtodiscuss.com/t/diabetes-strips/40150). As a low-calorie food, cucumbers make great training treats and can be used as a topper on your dog’s regular dinner. Go ahead and share a slice from your [salad](https://salad) with your [pup](https://howtodiscuss.com/t/when-do-puppies-open-their-eyes/42075). ## Cucumber Nutrition Facts Here are some of the nutritional details that you can expect with raw cucumbers (per 100g): | **Water** | 95.52 | | **Energy** | 15 kcal | | **Protein** | 0.65g | | **Total fat** | 0.11g | | **Carbohydrate** | 3.63g | | **Fiber** | 0.5g | | **Sugars** | 1.67g | | **Calcium** | 16mg | | **Iron** | 0.28mg | | **Potassium** | 147mg | | **Sodium** | 2mg | | **Vitamin C** | 2.8mg | _Health benefits of cucumbers_ **Water:** Cucumbers are 95% [water](https://howtodiscuss.com/t/how-much-water-should-you-drink-a-day/14933), making their hydration properties very high. **Calories:** The high water and very low sugar content mean this fruit is low calorie, with only 8 [calories](https://howtodiscuss.com/t/how-many-calories-do-you-burn-in-hot-yoga/28095) in a half-cup. **Fiber:** The skin or rind of cucumber supplies most of the soluble [fiber](https://howtodiscuss.com/t/how-many-grams-of-carbs-in-an-apple/17349). This means it soaks up water going through the digestive system. Soluble fiber aids in a food’s movement through your dog’s digestive tract and can improve stool quality. **Vitamin C:** This powerful antioxidant searches out and eliminates free-radical molecules that can damage cells. It also supports the immune system by reducing inflammation, fighting some [cancers](https://howtodiscuss.com/t/how-much-does-prostate-cancer-treatment-cost/31693), and reducing cognitive aging. **Vitamin K:** This [vitamin](https://howtodiscuss.com/t/get-the-right-vitamins/30617) is needed to aid in blood clotting and coagulation. **Vitamin B1 (Thiamine):** Regulates energy and carbohydrate [metabolism](https://howtodiscuss.com/t/metabolism/12697). **Vitamin B5 (Pantothenic Acid):** This helps with [energy](https://howtodiscuss.com/t/joule-unit/38458) production. **Vitamin B6 (Pyridoxine):** Supports red [blood](https://howtodiscuss.com/t/high-blood-pressure-types-symptoms-causes-effects-treatment-home-remedies/22806) cell generation, nervous system function, [hormone](https://howtodiscuss.com/t/somatropin/42598) regulation, and immune response. **Potassium:** This important mineral keeps your dog’s kidneys functioning well. It also supports efficient heart function, muscle function, and a healthy [digestive system](https://howtodiscuss.com/t/how-long-it-takes-to-digest-food/38335). **Manganese:** This micro-mineral supports the metabolizing of proteins and fatty acids. It also supports energy production and the role of ligament and [bone](https://howtodiscuss.com/t/how-many-bones-are-in-the-human-body/39423) maintenance. **Molybdenum:** This is a micro-nutrient required for normal cell function. It metabolizes carbohydrates and protects the body against excess [copper](https://copper). **Calcium, Zinc, and Iron:** These are present in trace amounts in a cucumber. They’re beneficial in bone growth and integrity and support [immune system](https://howtodiscuss.com/t/botox-immunity/44289) function. Because of the high water content in cucumbers, the nutrients are not as dense as some other fruits and veggies like broccoli, [strawberries](https://howtodiscuss.com/t/can-dogs-eat-strawberries/39591), pumpkin, and blueberries, but they still offer some nutrient value to your dog. > **Cucumbers are natural breath fresheners!** > > Cucumbers provide phytonutrients and phytochemicals that help freshen your dog’s breath. They also destroy the odor-causing bacteria present in the mouth. > > However, these crunchy fruits, or any other fruits and veggies, are not a good substitute for a consistent ■■■■ hygiene routine or a dog-approved toothpaste. ## How to Prepare Cucumbers for Dogs Now that you know of all the different ways that cucumbers can benefit your dog, it’s time to figure out the best way to serve this tasty treat to your pup. **1. Choose Organic Cucumber** If you can, it’s always beneficial to opt for organic produce. A lot of non-organic produce still carries trace amounts of harmful [pesticides](https://howtodiscuss.com/t/pesticide/11766), which can be problematic for you, your dog, and anyone else eating your produce. Choosing organic produce is cleaner and healthier. Also, organic farming is sustainable and environmentally friendly, which makes for a happier [planet](https://howtodiscuss.com/t/planet-colors/39872), as well as a happier pup. **2. Always Wash Your Veggies** It’s important to take the time to wash your [fruits](https://howtodiscuss.com/t/how-to-get-rid-of-fruit-flies-in-the-house/17886) and vegetables before you serve them to your dog. Take your cucumber and thoroughly rinse and wash it before serving to clean off any stray germs from the long trip from the farm to the store to your [home](https://howtodiscuss.com/t/home-improvement/41348). Clean food is healthier for both you and your pup! **3. Serve Cucumber Raw or Cooked** You can serve cucumber raw or cooked - it’s completely up to you and what your dog likes. As a general rule, raw cucumber is the simplest and will retain more [nutritional value](https://howtodiscuss.com/t/how-personalized-nutrition-plan-can-improve-your-health/32556). There is also a bonus of a little crunch that many [dogs](https://howtodiscuss.com/t/can-dogs-eat-rice/42169) love. While it’s true that some nutrients are enhanced through certain cooking processes, other nutrients are diminished. It all depends on the cooking method. Just make sure you make the pieces small enough for your pup to eat! **4. Skip the Seasoning!** Cucumbers are good for your [pup](https://howtodiscuss.com/t/how-to-stop-a-puppy-from-biting/431), but a lot of spices aren’t the best. A lot of seasoning can overpower your pup’s digestive system. Cucumbers are fine plain, but a pickle probably isn’t good for your dog since, in the fermenting process, a cucumber is filled with a lot of [sodium](https://howtodiscuss.com/t/naoh-molar-mass/39756) and spices. When cooking for your pooch, keep the ingredients whole and simple, as we do at Raw Bistro. **5. Make Cucumber a Special Treat for Your Pup** A cucumber shouldn’t be the only thing your dog eats in a day, but if they’re a huge fan, consider making it a training treat. You can cut cucumber up into small pieces to incentivize your [dog to learn a new trick](https://howtodiscuss.com/t/how-to-teach-your-dog-to-dance/29038), and feed them something [healthy](https://howtodiscuss.com/t/pet-insurance/19670) at the same time! It’s an easy way to keep the total amount of fruits and veggies to about 15-20% of your dog’s diet. **Serving Ideas** - Combine peeled, chopped cucumber with chunks of cantaloupe, [celery,](https://howtodiscuss.com/t/best-juicer-for-celery-best-way-for-juicing-celery/34333) and pear for a refreshing dog-friendly salad side dish - Slice cucumbers into rounds and remove the soft seedy center. Stuff cucumber slices with peanut butter or cream [cheese](https://howtodiscuss.com/t/cheese-how-to-make-cheese/295) (these make fun creepy “eyeball” treats at Halloween) - Freeze chunks or spears of peeled cucumber for a teething treat for your [puppy](https://howtodiscuss.com/t/puppy-hiccups/40249) - Use small pieces of cucumber as low-calorie training treats - Top their regular [dog food](https://howtodiscuss.com/t/can-dogs-eat-fish/39880) with small pieces of cucumber for a refreshing meal - Dehydrate slices of cucumber to create a chewy, summery [treat](https://howtodiscuss.com/t/can-dogs-eat-ice-cream/39703) ## Fruits and Vegetables Your Pet Can Safely Eat [![](https://img.youtube.com/vi/tLlIygte9Go/maxresdefault.jpg "Can Dogs Eat Cucumbers? [ANSWERED]") ](https://www.youtube.com/watch?v=tLlIygte9Go) As humans, we all know how important fruits and [vegetables](https://howtodiscuss.com/t/can-you-freeze-carrots/42049) are for our health. Abundant in vitamins, minerals, and fiber and low in calories, fruits and veggies are some of the most nutritious things that we can eat. It might also surprise you to know that some of these [delicious](https://howtodiscuss.com/t/how-to-lose-weight-eating-delicious-fast-food/14736) and nutritious foods can also be beneficial to your pet’s health. Although many of us like to share household food with our furry friends, not all human [food](https://howtodiscuss.com/t/thai-food/39935) is appropriate or safe for your pet to eat. To help you out, the experienced vets at Avondale Animal Hospital have put together this guide to fruits and veggies your pet can safely enjoy. **Fruits and Vegetables that are Safe for Dogs** Dogs are [omnivores](https://howtodiscuss.com/t/what-do-raccoons-eat/41252), meaning they can eat meat or plant-based food. In fact, most dog kibble is a combination of meat protein and [vegetable](https://howtodiscuss.com/t/can-dogs-eat-cauliflower/42173) matter. One way you can enrich your dog’s diet is by adding extra fruits and vegetables on top of their kibble. This can be especially beneficial for dogs suffering from weight problems or diseases, like diabetes. With that said, your canine companion can enjoy the taste and nutritional benefits of a large variety of different fruits and vegetables. Some of the healthiest fruits and veggies for dogs include: **Apples** Yes, dogs can eat apples. Apples are an excellent source of [vitamins A and C](https://howtodiscuss.com/t/how-to-get-the-right-vitamins/30615), as well as fiber for your dog. They are low in protein and fat, making them the perfect snack for senior dogs. Just be sure to remove the seeds and core first. Try them [frozen](https://howtodiscuss.com/t/chillfreez-frozen-food-transportation-company/35644) for an icy warm weather snack. **Bananas** Yes, dogs can eat [bananas](https://howtodiscuss.com/t/best-pet-insurance-for-small-dogs/21807). In moderation, bananas are a great low-calorie treat for dogs. They’re high in potassium, vitamins, biotin, fiber, and copper. They are low in cholesterol and sodium, but because of their high sugar content, bananas should be given as a treat, not part of your dog’s main diet. **Blueberries** Yes, dogs can eat [blueberries](https://howtodiscuss.com/t/can-dogs-eat-sweet-potatoes/41842). Blueberries are a superfood rich in antioxidants, which prevent cell damage in [humans](https://howtodiscuss.com/t/how-many-bones-are-in-the-human-body/39423) and canines alike. They’re packed with fiber and phytochemicals as well. Teaching your dog to catch treats in the air? Try blueberries as an alternative to store-bought treats. **Cranberries** Yes, cranberries are safe for [dogs](https://howtodiscuss.com/t/can-dogs-eat-ham/41488) to eat. Both cranberries and dried cranberries are safe to feed to dogs in small quantities. Whether your dog will like this tart treat is another question. Either way, moderation is important when feeding cranberries to dogs, as with any treat, as too many cranberries can lead to an upset stomach. **Cucumbers** Yes, dogs can eat [cucumbers](https://howtodiscuss.com/t/types-of-salads/263). Cucumbers are especially good for overweight dogs, as they hold little to no carbohydrates, fats, or oils and they can even boost energy levels. They’re loaded with vitamins K, C, and B1, as well as potassium, copper, magnesium, and biotin. **Cantaloupe** Yes, cantaloupe is safe for dogs. Cantaloupe is packed with [nutrients](https://howtodiscuss.com/t/how-many-net-carbs-in-an-apple/14890), low in [calories](https://howtodiscuss.com/t/how-many-calories-in-uranium/34049), and a great source of water and fiber. It is, however, high in sugar, so should be shared in moderation, especially for dogs who are overweight or have diabetes. **Mango** Yes, dogs can eat [mangoes](https://howtodiscuss.com/t/can-dogs-eat-mango/41711). This sweet summer treat is packed with four different vitamins: A, B6, C, and E. They also have potassium and both beta-carotene and alpha-carotene. As with most fruits, just remember to remove the hard pit first, as it contains small amounts of cyanide and can become a choking hazard. [Mango](https://howtodiscuss.com/t/how-to-cut-mango/15009) is high in sugar, so use it as an occasional treat. **Oranges** Yes, [dogs](https://howtodiscuss.com/t/can-dogs-eat-ham/41488) can eat oranges. [Oranges](https://howtodiscuss.com/t/orange-fruit/39125) are fine for dogs to eat, according to veterinarians, but they may not be fans of any strong-smelling citrus. Oranges are an excellent source of vitamin C, potassium, and fiber, and in small quantities, the juicy flesh of an orange can be a tasty treat for your dog. Vets do recommend tossing the peel and only offering your dog the flesh of the orange, minus any seeds. Orange peel is rough on their digestive systems, and the oils may make your dog literally turn up their sensitive nose. **Peaches** Yes, [peaches](https://howtodiscuss.com/t/peachtree/20191) are safe for dogs to eat. Small amounts of cut-up fresh or frozen peaches are a great source of fiber and vitamin A, and can even help fight [infections](https://howtodiscuss.com/t/how-to-get-rid-of-cold-sores/14714), but just like cherries, the pit contains cyanide. As long as you completely cut around the pit first, fresh peaches can be a great summer treat. Skip canned peaches, as they usually contain high amounts of sugary syrups. **Pears** Yes, dogs can eat pears. Pears are a great snack because they’re high in copper, [vitamins C](https://howtodiscuss.com/t/the-ordinary-vitamin-c/34141) and K, and fiber. It’s been suggested that eating the fruit can reduce the risk of having a stroke by 50 percent. Just be sure to cut pears into bite-size chunks and remove the pit and seeds first, as the seeds contain traces of cyanide. Skip canned pears with sugary syrups. **Pineapple** Yes, [pineapple](https://howtodiscuss.com/t/pineapple-tree/38422) is safe for dogs to eat. A few chunks of pineapple is a great sweet treat for [dogs](https://howtodiscuss.com/t/best-dog-breed/37646), as long as the prickly outside peel and crown are removed first. The tropical fruit is full of vitamins, minerals, and fiber. It also contains bromelain, an enzyme that makes it easier for dogs to absorb proteins. **Raspberries** Yes, dogs can eat raspberries. [Raspberries](https://howtodiscuss.com/t/raspberry-tree/12549) are fine in moderation. They contain antioxidants that are great for dogs. They’re low in sugar and calories, but high in fiber, manganese, and vitamin C. Raspberries are especially good for seniors [dogs](https://howtodiscuss.com/t/essential-oils-bad-for-dogs/12536) because they have anti-inflammatory properties, which can help aging joints. However, they do contain small amounts of xylitol, so limit your dog to less than a cup of raspberries at a time. **Strawberries** Yes, [dogs can eat strawberries](https://howtodiscuss.com/t/can-dogs-eat-strawberries/39591). Strawberries are full of fiber and vitamin C. Along with that, they also contain an enzyme that can help whiten your [dog’s teeth](https://howtodiscuss.com/t/how-many-teeth-do-dogs-have/39727) as he or she eats them. They contain sugar, so be sure to give them in moderation. **Watermelon** Yes, [dogs can eat watermelon](https://howtodiscuss.com/t/can-dogs-eat-watermelon/38781). It’s important to remove the rind and seeds first, as they can cause intestinal blockage, but watermelon flesh is otherwise safe for dogs. It’s full of vitamin A, B-6, and C, as well as potassium. Watermelon is 92 percent [water](https://howtodiscuss.com/t/how-many-ounces-in-a-gallon-of-water/40051), so it’s a great way to help keep your dog hydrated on hot summer days. **Broccoli** Yes, broccoli is safe for [dogs](https://howtodiscuss.com/t/what-do-groundhogs-eat/39967) to eat in very small quantities and is best served as an occasional treat. It is high in fiber and vitamin C and low in fat. However, [Broccoli](https://howtodiscuss.com/t/how-to-cook-broccoli/14805) florets contain isothiocyanates, which can cause mild-to-potentially severe gastric irritation in some dogs. Furthermore, broccoli stalks have been known to obstruct the esophagus. **Brussels sprouts** Yes, [dogs can eat Brussels sprouts](https://howtodiscuss.com/t/can-dogs-eat-brussel-sprouts/42194). Brussels sprouts are loaded with nutrients and antioxidants that are great for humans and dogs, alike. Don’t overfeed them to your dog, however, because they can cause lots of gas. [Cabbage](https://howtodiscuss.com/t/benefits-of-vegetables/37321) is also safe for dogs, but comes with the same gassy warning! **Carrots** Yes, dogs can eat [carrots](https://howtodiscuss.com/t/can-you-freeze-carrots/42049). Carrots are an excellent low-calorie snack that is high in fiber and beta-carotene, which produces vitamin A. Plus, crunching on this orange veggie is great for your dog’s teeth (and fun). **Celery** Yes, [celery](https://howtodiscuss.com/t/best-juicer-for-celery-best-way-for-juicing-celery/34333) is safe for dogs to eat. In addition to vitamins A, B, and C, this crunchy green snack contains the nutrients needed to promote a healthy heart and even fight cancer. As if that wasn’t enough, celery is also known to freshen doggy breath. **Green beans** Yes, dogs can eat green [beans](https://howtodiscuss.com/t/beanfeast/32780). Chopped, steamed, raw, or canned – all types of green beans are safe for dogs to eat, as long as they are plain. Green beans are full of important vitamins and minerals and they’re also full of fiber and low in calories. Opt for low-salt or no-[salt](https://howtodiscuss.com/t/salt/7587) products if you’re feeding canned green beans to your dog. **Peas** Yes, dogs can eat peas. Green peas, snow peas, sugar snap peas, and garden or English peas are all OK for [dogs](https://howtodiscuss.com/t/what-is-a-dog-crate-for/38406) to find in their bowl on occasion. Peas have several vitamins, minerals, and are rich in protein and high in fiber. You can feed your dog fresh or frozen peas, but avoid canned peas with added sodium. **Spinach** Yes, dogs can eat [spinach](https://howtodiscuss.com/t/types-of-salads/263), but it’s not one of the top [vegetables](https://howtodiscuss.com/t/benefits-of-vegetables/37321) you’ll want to be sharing with your [pup](https://howtodiscuss.com/t/puppy-hiccups/40249). Spinach is high in oxalic acid, which blocks the body’s ability to absorb calcium and can lead to kidney damage. While your dog would probably have to eat a very large amount of spinach to have this problem, it might be best to go with another vegetable. **Fruits and Vegetables that are NOT safe for Dogs** While there is a range of [fruits](https://howtodiscuss.com/t/fruits-that-starts-with-r/34755) and veggies that are safe for your dog to consume, some varieties can also be toxic. Some of the most popular fruits and veggies that you should avoid feeding your dog include garlic, onion, mushroom, avocado, and rhubarb. If you are unsure if your pet should be eating something, make sure you ask one of our vets, and we will be happy to answer any questions regarding your pet’s [health](https://howtodiscuss.com/t/best-pet-health-insurance/27439) and nutrition. **Avocado** No, dogs should not eat avocado. While [avocado](https://howtodiscuss.com/t/how-many-calories-in-an-avocado/14786) may be a healthy snack for dog owners, it should not be given to dogs at all. The pit, skin, and leaves of [avocados](https://howtodiscuss.com/t/here-you-get-best-avocado-oil-nutrition-facts-benefits/31635) contain persin, a toxin that often causes [vomiting](https://howtodiscuss.com/t/dizziness-and-vertigo/28881) and diarrhea in dogs. The fleshy inside of the fruit doesn’t have as much persin as the rest of the plant, but it is still too much for dogs to handle. **Cherries** No, dogs should not eat cherries. Except for the fleshy part around the seed, cherry plants contain cyanide and are toxic to [dogs](https://howtodiscuss.com/t/can-dogs-eat-fish/39880). Cyanide disrupts [cellular](https://howtodiscuss.com/t/cellular-respiration-equation/39040) oxygen transport, which means that your dog’s blood cells can’t get enough oxygen. If your dog eats cherries, be on the lookout for dilated pupils, difficulty [breathing](https://howtodiscuss.com/t/halitosis-bad-breath-everything-you-need-to-know-about-halitosis-bad-breath/22887), and red gums, as these may be signs of cyanide poisoning. **Grapes** No, dogs should never eat [grapes](https://howtodiscuss.com/t/grapeseed-oil-for-skin/31679). Grapes and raisins (dried grapes) have proved to be very toxic for dogs no matter the [dog’s breed](https://howtodiscuss.com/t/best-dog-breed/37646), sex, or age. In fact, grapes are so toxic that they can lead to acute sudden [kidney failure.](https://howtodiscuss.com/t/what-is-kidney-failure/22175) Always be mindful of this dangerous fruit for dogs. **Tomatoes** No, dogs should avoid [tomatoes](https://howtodiscuss.com/t/how-to-make-tomato-juice/30739). While the ripened fruit of the tomato plant is generally considered safe for dogs, the green parts of the plant contain a toxic substance called solanine. While a dog would need to eat a large amount of the tomato plant to make him or her sick, it’s better to skip tomatoes all together just to be safe. **Asparagus** No, dogs should not eat [asparagus](https://howtodiscuss.com/t/20-best-foods-to-control-diabetes-meal-planning/33124). While asparagus isn’t necessarily unsafe for dogs, there’s really no point in giving it to them.
