Health & WellnessCan I add chicken to my dog's Hill's S/D prescription urinary food?
The prescription diet is required for pets that have been found to develop urinary crystals/stones. If your vet detected crystals, then she must be on the urinary food or she could develop a urinary stone and possibly even require surgery in the future.
We as veterinarians are told that pets shouldn't have anything in addition to the prescription diet b/c this could potentially lead to failure of the diet to help regulate her condition. However, you can opt to get some of the canned Hill's S/D food to mix in with it.
I hope that this helps. Best of luck with Mamie moving forward. Take care.
