How to Transition My Dog to a Vegetarian Diet
There are many reasons dog owners transition their dogs to vegetarian diets. Sometimes a dog needs a diet low in protein for health reasons. Sometimes a vegetarian diet is the only option for a dog with severe food allergies. Regardless of the reason for transitioning your dog to a vegetarian diet, it should not be done all at once, but slowly over at least a week. A slow transition is key to keeping your dog from experiencing the digestive upsets associated with a new diet.
