According to the internet, you can. HOWEVER, while you’ll find lots of recipes for vegan or veggie dog food online, it isn’t necessarily advisable to try making your own puppy chow. No matter what your reasons are for feeding your pooch a vegan or vegetarian diet, his or her number one priority will always be a balanced diet. Online recipes may not be able to guarantee that your dog is getting all the protein, fat, micronutrients, fiber, and building blocks that they need – and this is particularly important for growing puppies. We recommend that you stick to vet-developed recipes that have met the key AAFCO standards to ensure that your puppy grows up healthy, happy, and well.
