If you find yourself with an abundance of zucchini and a dog with pleading eyes, you might wonder, “Can dogs eat zucchini?” My garden did really well this year, and I had so much zucchini that I didn’t know what to do with it all! As I harvested the zucchini, I noticed my dog watching with great interest. At that moment I thought maybe I found someone to help me eat the zucchini, but is it safe for dogs to eat zucchini?

Dogs can eat lots of the same foods that you eat, but not all of them. If you’re thinking about sharing a particular food with your dog, it’s important to ensure that it won’t cause your pet any harm and to know for sure the human foods dogs can eat. Here’s what you need to know about sharing zucchini with your dog.

Is It Safe for My Dog to Eat Zucchini?

Zucchini is very safe for dogs to eat. You can definitely enjoy giving your dog zucchini and not worry about harmful effects. In fact, zucchini has many health benefits for dogs, just as it does for humans.

Zucchini is high in water and fiber content.1 Having high water and fiber makes this food beneficial for the intestinal tract. The water and fiber content in zucchini allows for a reduced risk of constipation as well as an increase in the health of the good bacteria in the gut. High fiber can also help reduce hunger for those dogs that are on a weight loss diet.2

There are plenty of different vitamins and minerals in zucchini. This delicious food has plenty of vitamin A. Vitamin A is known to support healthy vision and the immune system. There is also a variety of other nutrients, including vitamin C, manganese, potassium, vitamin B6, and several others.3

Zucchini also contains antioxidants. Notable antioxidants in zucchini include lutein, zeaxanthin, and beta-carotene.4 These antioxidants are helpful for supporting healthy skin, heart, and eyes.56

Most dogs will enjoy the addition of zucchini to their diet, and that’s great because it is really healthy and beneficial food!

Minimal Safety Concerns and Risks Associated with Zucchini for Dogs

There are not many safety concerns with feeding your dog zucchini. Zucchini is really well-tolerated and enjoyed by most dogs. There are just a few things to think about before feeding your dog zucchini.

As with any food, going overboard and feeding really large volumes can cause gastroenteritis/intestinal upset.7 Especially if you are offering this food for the first time, start with small bites to make sure your pup enjoys this food without intestinal irritation.

If your dog has difficulty chewing, due to dental disease, age, or prefers to swallow food whole it may be best to serve your dog cooked or steamed zucchini that is softer.

Finally, don’t just take a whole zucchini from the garden and give it to your dog. Don’t even offer a large chunk. It’s best to chop or slice the zucchini so that your dog cannot swallow large pieces. It is possible if your dog swallows a huge section of zucchini that this can become lodged in the esophagus or the intestinal tract, resulting in a trip to the veterinary ER.8

How Much Zucchini Can I Feed My Dog?

As always, veterinary nutritionists recommend feeding your dog his balanced dog food as 90% of the calories he takes in. The remaining 10% of calories can be given as treats or other foods you would like to supplement.

For example, according to The Ohio State University Veterinary Medical Center’s Basic Calorie Calculator, a typical 25-pound dog needs approximately 700 calories per day. This means that 70 calories per day can come from treats. Remember, that means all treats you would like to give in a day should total 10% of his calories.

Zucchini is approximately 20 calories per cup.9 Technically, you could give that 25-pound dog more than 3 cups of zucchini per day. That being said, I would recommend feeding less than 3 cups of zucchini, so there are more calories left for other treats.

Always make sure that your dog is tolerating small amounts of zucchini before offering a large portion. I would recommend starting with a few bites of zucchini and gradually increasing how much you give over time. If any vomiting or diarrhea starts, then discontinue feeding the zucchini.

How to Prepare Zucchini for Your Dog

Zucchini can be fed to dogs in many different ways. It is perfectly acceptable to offer raw zucchini to your dog, provided he is capable of chewing it.

You can also steam, cook, or sauté zucchini for your dog. However, remember to avoid seasoning, salt, onions, garlic, or other foods or flavors that might be dangerous or irritating to your dog.

It is ideal to slice or chop the zucchini so your dog doesn’t choke or have intestinal blockage due to large pieces of zucchini.

Tips from Our Vets

The following is a list of tips on how to think about what human foods are (and may not be) safe for your dog from Dr. Jennifer Coates’ article on Foods Dogs Can and Cannot Eat.

There are some human foods that dogs can eat safely, as well as some human foods dogs can’t eat.

If you have a dog, you might be used to seeing adorable puppy eyes begging for a bite of, well, anything that you happen to be eating.

While it’s natural to want to share human food with your furry pal, many of the foods we eat are toxic to dogs. Some reasons foods may be harmful to your pup include:

  • Foods that are a problem due to our physiological differences (foods we can handle that a dog’s stomach can’t)
  • Other foods aren’t toxic, but are still potentially dangerous for dogs because they are hard to digest
  • Another category of foods that are a problem for dogs are foods that may contain high levels of fat

Some tips and words of caution if you are feeding your pet human foods:

  • Always keep in mind that new foods of any kind, including switching to a different dog food, can cause stomach upset.
  • When you find a human food you’d like to share with your pup, go slowly. Give small amounts at first and watch for any problems like vomiting or diarrhea before giving more.
  • Remember that treats should make up less than 10% of your dog’s diet. So all of the foods that are safe for your dog should be given in moderation to avoid weight gain and nutrient excesses and deficiencies.

What To Do if Your Dog Eats Something He Shouldn’t

Now that you know what foods are safe for dogs, it’s a good idea to know what to do if your pup eats food that’s toxic to dogs.

If your dog does end up eating something he shouldn’t, try not to panic. You have a few options for getting the help your dog needs:

  • The first is to call your dog’s veterinarian, who can advise you to either come into the office or to watch for signs of poisoning, obstruction, or other potential problems.
  • If it’s after hours, you can try calling an emergency veterinarian.
  • Another option is to call a pet poison control line. Be aware that there is a fee to use these services. Two that we can recommend are the ASPCA Animal Poison Control at (888) 426-4435 and the Pet Poison Helpline at (855) 764-7661.

In some cases, you might be told to induce vomiting in your dog. It is helpful to keep hydrogen peroxide on hand in case you need to do this.

Do not induce vomiting unless your veterinarian or someone from one of the pet poison control hotlines advises you to do so, however, because in some cases, vomiting can make the situation worse. [efn_note]Is it ever safe to induce vomiting? November 19, 2019. Accessed April 28, 2021.[/efn_note]
