Perhaps you didn’t know this, but zucchini is a fruit! Botanically, it’s classified as a fruit as it forms the flower, and it’s considered a type of berry, just like cucumbers and pumpkins!

Nonetheless, fruit or a vegetable, zucchini has proven to have many health benefits for humans. But, you’ve probably wondered –  can dogs eat zucchini too?

Some vegetables and fruit can seriously endanger a dog’s health, and it’s essential to know which one should be included in their diet. If you want to find out whether dogs can eat zucchini and also some more information, read along!

Can Dogs Eat Zucchini?

Yes, dogs can eat zucchini! Zucchini is perfectly safe for dogs. However, it is not considered necessary for your dog’s diet, but it will provide some valuable nutrients such as potassium and vitamin C.

Overall, zucchini is a good alternative for high-calorie treats, as it is low in cholesterol and fat. An excellent treat for dogs that need to lose some weight but still eat healthily!

But let’s look at the nutritional value of zucchini per 100gr:

Energy17 calories
Protein1 gr
Total Fat0,3 gr
Carbs3 gr
Sugar1 gr
Fiber1 gr
Vitamin A40%
Vitamin C14%

As you can see, zucchini is low in fat, making it a great snack for dogs as high amounts of fat are harder for dogs to digest. Also, too much fat can lead to indigestion and inflammation of the pancreas, known as pancreatitis

Instead, zucchini contains reasonable amounts of fiber that improves a dog’s digestion, and they can more effectively absorb necessary nutrition.

Zucchini also contains small amounts of vitamin K, copper, phosphorus, folate, thiamine, vitamin B6, iron, calcium, and zinc. Furthermore, it contains antioxidants such as beta-carotenelutein, and zeaxanthin, which help protect the body from damage by free radicals.

How Much Zucchini Can Your Dog Eat?

Zucchini is much easier for dogs to digest than other squashes, and can be even eaten raw and with seeds. However, too much healthy stuff can also be bad for your dog, so don’t get carried away with zucchini. 

Zucchini should be fed in moderation, and more like as an occasional treat. Your dog’s diet should be focused on 95% of high-quality dog food and meat and 5% of human food (veggies, fruit, fiber, etc.).

Too much zucchini or any other type of veggies, fruit, or fibers, can lead to digestive issues in dogs. Also, always observe your dog closely anytime you serve new or unconventional food, as it could lead to possible diarrhea or vomiting.

Amounts of zucchini fed to your dog should not exceed 10% of your dog’s overall diet.

Here’s a chart for the more precise intake of zucchini:

Small size dog (20-40 pounds):4-10 gramsOnce in a few days
Medium size dog (50-100 pounds):8-12 gramsOnce in a few days
Large size dogs (100-150 pounds):17-34 gramsOnce in a few days

In the end, you don’t have to stick to this chart strictly, but it will give you some idea of how much zucchini your dog can eat. We strongly advise serving your dog zucchini only once in a while, mixed with other quality dog food or as a special healthy treat.

Safety Precautions Before Feeding Zucchini

Overall, zucchinis are not toxic to your dog and are pretty much safe for them to eat. 

However, sometimes zucchini and its leaves can be bitter and contain toxins called cucurbitacins that can be dangerous to pets and humans. Put simply; those are biochemicals found in plants and give off a bitter flavor, and they are very toxic.

The best option is to buy organic zucchinis or even smaller ones, as large zucchinis are more likely to be bitter and toxic. 

Given this, if you notice any of the following symptoms contact your wet immediately:

  • Diarrhea
  • Nausea
  • Vomiting
  • Kidney failure (inability to urinate)
  • Anxiety
  • Loss of coordination
  • Drooling
  • Oral irritation
  • Convulsions
  • Tremors
  • Heart issues.

Also, don’t ever serve your dog big pieces of zucchini. Most dogs usually gobble their food without much chewing, so large pieces or a whole zucchini may cause your dog to choke. To minimize the risk, make sure you chop zucchini into smaller pieces.

Furthermore, always serve zucchini in moderation as we already mentioned above. Too much of any food or treat can lead to nutrient imbalances. If your dog eats too much too soon, it can lead to stomach upset and digestion problems such as sickness, diarrhea, and vomiting. 

Benefits Of Zucchini

As we’ve already mentioned, zucchini is a very healthy food product packed with many minerals, vitamins, and antioxidants. Veterinarians agree that zucchini is one of the best vegetables you could give to your dog as they are low-calorie and nutrient-filled.

Dietary fiber will improve digestion and keep your dog full. That could be great for dogs that need to lose some weight. Moreover, zucchini can replace high-calorie treats, such as milk bones and jerkies. 

Here are some other health benefits:

  • Strong bones and muscles due to calcium and potassium
  • Smoother and healthier skin and coat due to vitamin C
  • Antioxidants prevent diseases
  • Healthy hydration level
  • Beta-carotene improves vision and pigmentation
  • Reduced unhealthy cholesterol levels
  • B vitamins prevent kidney stones, asthma, and allergies
  • Calcium prevents muscle cramping
  • Magnesium improves cardiovascular health
  • Manganese promotes healthy ligaments
  • Phosphorus promotes heart health and healthy teeth
  • Potassium promotes healthy brain function
  • Selenium promotes healthy prostate
  • Zinc helps the body heal
  • Vitamin A keeps hormone levels balanced and supports bone growth and immune response

Preparing Zucchini For Your Dog

Zucchini is a wonderful light snack and can be prepared in various ways. Unripe and small zucchini taste the best, as larger ones can often be too bitter. Also, make sure the zucchini you pick is firm and not squishy.

Firstly, wash the zucchini thoroughly and cut off the stalk of the vegetable. Then, cut it into small, bite-sized pieces or circles. Serving raw zucchini is fine, but for better digestion, it is better to cook it or boil it first. Also, make sure to peel off the zucchini’s skin, as it can sometimes cause stomach problems.

Cooking methods:

  • Steaming
  • Boiling
  • Fermenting
  • Baking
  • Grilling

All of the methods above are fine, just make sure you serve a blend of zucchini. Don’t use any add-ons such as seasonings, salt, or even oil. Those could seriously endanger your dog’s health and can also be lethal. 

Salt can cause pancreatitis, increase blood pressure, or cause dehydration. Onions and garlic can seriously damage red blood cells and lead to hemolytic anemia. If this condition isn’t treated promptly, it can kill your dog.

In addition, you can put zucchini into the freezer and slice it into cubes or circles. That could be a great treat during the summer months. However, you shouldn’t give your dog baked zucchini products because they are full of calories, fat, sugar, and other seasonings that could upset your dog’s stomach. Another reason for this is that they contain sweeteners called xylitol, which are poisonous for dogs.

Furthermore, you can also serve zucchini noodles to your dog, just make sure you don’t use commercial ones full of salt, pepper, onion, garlic, and sugar. Avoid frying zucchini as most nutrients will be gone, and greasy food is a big no for dogs.
