Quote: ” The vet has recommended putting her on a diet of Royal Canin Gastrointestinal. ”
I would stay with the therapeutic diet at least till the dog has been stable for a few months, then consider diet changes if your vet approves. I know of no commercial product that would compare.
I wouldn’t do home cooked unless under the guidance of a veterinary nutritionist and I suspect it would be expensive.
Hope this helps: excerpt from http://skeptvet.com/Blog/2016/07/more-nonsense-from-holistic-vets-about-commercial-therapeutic-diets/
Regarding price, good companies invest in research, that goes into designing the food, sometimes funding basic research that would further our knowledge on particular diseases (without an immediate product to market and sell) plus trials in healthy and diseased pets, etc. So, I understand why a veterinary diet from a responsible company costs more money, not because the ingredients are more expensive, but due to the knowledge invested behind it.
