My poor old pooch can't tolerate protein so for years has been eating Hill's Prescription Diet Z/D Food Sensitivities canned food. It's been out of stock for ages, apparently nationally. I've spoken to my vet who suggested Royal Canin Veterinary Diet Hypoallergenic canned food - which he also got on well with but this is now also out of stock! Does anyone else's dog eat either of these and what are you feeding them at the moment? Any other suggestions?
