Does feeding the same protein source long term cause food allergies in dogs? Why or why not? Please explain, thanks!

Typically no. Actually, feeding the same protein source is best for your dog. If you continually change they can get gastrointestinal upset. It isn't very common for dogs to be allergic to food, although it can happen. Thank you for using Petco Pet Education Center, formerly Petcoach.
