Hi, when you tried the 5 limited ingredient kibbles did you try kibbles with different proteins? I found Patch did really well when he ate a kibble that was just Fish & Rice, some grain free kibbles made him itch, smell bad & did very sloppy poos….. Patch has Food Sensitivities, Environment Allergies & IBD…..
Purina has their HA Hydrolyze kibble & the ingredients are similar to the Hills Z/D Ultra…Are you feeding the Hills Z/D Ultra with Starch as the first ingredient?? Purina HA Hydrolyzed is cheaper then the Hills Z/d.. Chewys has free delivery on Purina HA 25lb bag for $81 Auto delivery…you’d need your vet to write a veterinary Prescription…

Try a kibble with just Fish & Rice mix with the Hills Z/d add 1/4 cup per meal for 3-4 days & see if there’s any change…. also now he’s doing better on the Hills Z/d, now you start introducing 1 new food to the diet over 2-4 weeks & find out what foods he’s sensitive tooo…I was adding a new food at breakfast time & then I knew when Patch did his poos or if his ears started to itch & he was shaking his head, or had his red paws he couldn’t eat that ingredient… I found chicken gave him red paws & sloppy poo, barley, wheat & corn, makes him smell & have itchy ears & red paws, its taken me 3 years & I know what he can eat & cant eat…
Have you tried Canidae Pure Sea?? a lot of dogs with allergies do really well on the Pure Sea & you don’t need to feed as much kibble cause the Kcal per cup is 496, Canidae, Pure Sky has 520Kcals per cup & is money back guaranteed if your dog has any problems…
