The Risks Associated with Feeding Your Dog a Vegetarian Diet

dog eating carrot blogFrom health reasons to personal beliefs, people decide to adopt a vegetarian or vegan lifestyle for a variety of reasons. While the validity of the age-old claims that meat is “good for us” is presently being questioned more than ever, this same debate is carrying over to dogs. Do dogs really “need” meat as much as we think they do?

Since cats are natural carnivores, it’s generally agreed upon by veterinary professionals that a vegan or vegetarian diet is not appropriate for felines.  While a vegetarian diet may be less risky for dogs, complications can occur, because canines are historically a scavenging carnivore – who eats meat and plants, but requires lots of protein and sufficient amino acid intake. Any dietary decisions or changes should be discussed with your pet’s veterinarian.

Below are are three risks associated with putting your dog on a vegetarian or vegan diet:



1. Inadequate Protein Intake: It’s recommended that dogs get 25 grams of protein for every 1,000 calories. While this may be possible with a vegetarian diet, it’s certainly challenging. Luckily, there are many fruits and vegetables that have high protein content, such as spinach, chickpeas, kale, black beans, etc. which are all safely edible for dogs. In fact, black beans have more protein gram for gram than beef! Also, it is very simple to supplement the plant-based sources of protein with eggs, which are still vegetarian (but not vegan).

2. Amino Acid Imbalance: A vegetarian diet can create an imbalance of amino acids, like taurine and L-carnitine, which can lead to health issues like dilated cardiomyopathy, eye conditions, and stunted growth. However, many of the amino acids that meats contain can be found in eggs as well as many plant products. Another option is to use supplements to ensure that your animal has the amino acids it needs to thrive.

“Cook it first, please!”

3. Vitamin deficiency: Certain vitamins and minerals are consumed ideally (or only) from animal products. These include vitamin B, calcium, iron, and phosphorus. As I said, supplements and vitamins can be used, or a wide variety of plant products can be explored. Vitamin B12 is the only vitamin that dogs (and humans) primarily get from meat, so that is a vitamin that you will probably have to consider buying if you want your dog to be vegetarian.

Keep in mind, if you want your dog to be vegetarian (or even vegan, which is a far more complicated situation), you will have to gradually ease them into t heir new diet. You cannot under any circumstances just suddenly cut out meat one day all at once. Begin by slowly removing the meat little by little and filling the void with other protein-rich fruits, vegetables, legumes, grains, and more. Be prepared to get extremely creative, because you will find that your dog is a pickier eater than you thought. While most dogs openly embrace vegetables and fruits, it may take a little bit of extra motivation on your part to convince them to eat it.

"But...can't I have both...?"

“But…can’t I have both…?”

It’s a good idea for dogs on a vegetarian diet to go in for wellness exams more frequently than the average canine. That way, if there is a deficiency of any kind, you can tackle the problem as soon as possible, and find another method to supplement your dog’s diet. Please understand that while going vegetarian is relatively easy for humans (especially nowadays), there is much more to be considered when having your dog go meatless. Your vet may recommend regular bloodwork to keep an eye on your pet’s health and possibly dietary supplements to help boost your pet’s nutrition.

Perhaps a more realistic option would be to drastically decrease your dog’s meat intake rather than cutting it out entirely. After all, it could be counterproductive to deny your dog meat due to your convictions about animal cruelty and death in the factory farm industry – if your dog is suffering as a result. Make sure that you are taking it slow, getting veterinary guidance, and researching as much as you can while you are transitioning your dog onto a veggie diet!

"Alright, let's try it!"

“Alright, let’s try it!”

If you personally have a vegetarian (or even vegan) diet regimen for your dog that works amazingly, please share! There are many people that argue against a vegetarian diet for dogs, but there is a growing number of people like YOU who want to explore the option but don’t know where to start. A good place to begin educating yourself is to read this article from PetMD, and this other article by Pets.WebMD! There are also very helpful online communities and message boards such as this one that you can check out and even post your inquiries for further help and guidance. Good luck, and keep us updated on your progress!

    Good Information to know. Lots of people are adopting vegetarian/vegan lifestyles.

    “Since cats are natural carnivores, it’s generally agreed upon by veterinary professionals that a vegan or vegetarian diet is not appropriate for felines”

    Absolutely false. Most domesticated cats are healthier and thrive better on a Vegan diet, and only a small percentage are not able to thrive Vegan. All dogs thrive better on a Vegan diet.

    How is it right to kill other animals merely to feed them to your nonhuman family? Their lives are morally not worth less than the lives of our cats and dogs, just like our lives are not worth more than the lives of a cow or chicken, etc.

    Here’s some further info (warning: the “disgusting truth” link has one graphic image):

      Thank you so much for your post! I made this post with the intention of getting other vegetarian/vegan pet owners’ feedback to see what they use as their tried-and-true method, so I appreciate your input. 🙂 I recently cut out meat completely from my diet due to the same feelings you have about the unnecessary/cruel practice of killing animals to feed ourselves, and I do still feel weird feeding my dog meat when it directly conflicts with my scruples. My dog actually loves vegetables and all food actually so I was thinking of trying a vegetarian/vegan diet for her as well. I will check out your resources and work them into her diet and document the results! Thanks again!

    Anyone who forced their pet to adopt the vegetarian/vegan lifestyle is a douchebag – no excpetions. The only reason to ever decrease protein intake is for health reasons. So unless your pet has a health condition that requires them to eat a reduced formula of pet food, or unless your pet is a senior pet and requires senior formula pet food, feed them whatever is healthiest for them, and that includes meat. Seriously people, don’t be assholes to your pets.

      Hey Benjamin, that has been the point of view adopted by most pet owners for a long time, but recently there seem to be many people (including Colin, who commented on this post as well) who have had much success with feeding their dogs and even cats vegetarian/vegan diets. I mean, our society in general is constantly progressing and finding out that age-old ways of thinking are actually not accurate – so I definitely believe that dogs and cats could be fed meatless diets. If done properly of course and with close monitoring of their health!

      Think of it this way – many animal lovers (including myself) love ALL animals so much that they refuse to eat them. Well, if you hold all animals on the same level of compassion and empathy, then it would feel pretty weird to feed your ANIMAL another ANIMAL’s flesh to eat. Right? I don’t think that’s “forcing” anything upon them – as long as the dog is getting its proper nutrients and is healthy, I think they are fine with it.

    I just started growing baby greens and sunflower shoots for my daughters 13 yr old Corgi mix.
    She has been healthy, but losing her usual playfulness, so I suggested adding greens to her diet about 2 months ago.
    WOW! What a change! and nearly immediate.
    She is alert, and playful now. Her coat is improving, and after years of veterinarians failing to cure her “itchiness”, the greens seem to be bringing her relief from itching too!
    There is also a marked decline when the greens are not available consistently. The improvement has been so successful, it has gotten the attention of other dog owners, and they want me to grow more greens for their animals too. The dog is completely off “carcass” meat. Her protein intake, is now supplied by 2 organic unfertilized chicken eggs per day.
