Hi Ryan,
Is the Hills Z/d helping with his allergies (Skin) ? does he suffer with Environment allergies or Food sensitivities or does he have both? my boy suffers with both, if his skin seems better on the Hills Z/D it’s probably the high Omega fatty acids they put in the Vet Diets, start looking for another limited ingredient single protein kibble, if the California Natural ingredients didn’t really help read what the ingredients were in the California Natural, I’m pretty sure the CN Kangaroo formula has Red & Green Lentils these ingredients will not help if a dog has sloppy poos/diarrhea you need to aviod Lentils…
With environment allergies baths are best in a medicated shampoo, I found Malaseb works the best for my boy, twice a week or weekly baths, washes off the allergens on the dog skin/paws if he’s doing sloppy poos then Sweet Potatoes & Potato is the best to firm up poo’s, the only way a dog will get yeasty skin & paws is if he is sensitive to an ingredient & from environment allergies, Potato does not cause yeasty skin/paws in dogs this is a Myth, thats if he gets yeasty smelly skin & paws….
You can start an elimination food diet & start working out what foods he can & cant eat, Potato & Sweet Potato firmed up my boy poos up with his IBD now he doesnt need his anal gland expressed no more, sometimes after Patch has done a poo I see the fluid running down his black bum, when I go home I get a baby wipe & wipe that area, after I started feeding Patch “Taste Of The Wild” Sierra Mountain Roasted Lamb, it has just Lamb as the protein source then Sweet Potato, Potato, Peas, Canola Oil, Egg I started rotating & feeding “Canidae” Pure Wild Boar, Patch has had no more anal gland problems..
Here’s the Canidae site to look at formula’s & ingredients,

Canidae also have their Pure Sea & Pure Sky formula’s they’re really good for skin problems cause they’re very high in omega fatty acids, Canidae also make another brand called “Under The Sun” but its yellow pea & chickpea heavy, I’d avoid if your dogs has sloppy poo problems..
or look at “4Health” Special Care, Sensitive Stomach” it just has Potato & Egg excellent for doing an elimination diet once your dog is doing well you start adding 1 new ingredient for 6 weeks & see does he react in those 6 weeks there’s also “4Health” Special Care, Sensitive Skin formula it has Hydrolyzed Salmon but has more ingredients then the 4Health Sensitive Stomach formula has, or there’s other “4Health” formula’s Turkey & Potato, Duck & Potato, Whitefish & Potato look for a formula with the least ingredients just google “4health Special Care, Sensitive Stomach” & you’ll see all the 4health formula’s …
Hills Z/d is Guaranteed Money back so I’d take back the remaining Z/D kibble, keep a bit of the Z/d kibble to help introduce a new kibble & tell the lady at the vet counter what is happening, Hills like feed back how your dog went on their vet diets, you can even send Hills an email & have a Vet Nutritionist call you back they will help you with the vets diet, which is best to try next, Hills have their Potato & Duck skin formula or their Science Diet Sensitive Skin formula, the Z/D had been changed twice in the last 5yrs & the Hills I/d Digestive Care has just been changed & improved again, thats 3 times in 5 yrs so Hills must get a few complaints with their vet diets….
There’s “Royal Canin” Hydrolyzed Protein HP formula or Royal Canin have their Select Proteins, PR- Potato & Rabbit, PV Potato & Venison, Skin Support SS is Rice & Fish, that’s if you want to try another vet diet again, or look for a premium limited ingredient dog kibble & add your own omega oil, just buy some Fish/Krill Oil capsules & give 1 capsule with 1 of his meals a day but only start adding the Krill Oil capsules once he’s stable on the new kibble as fish /Krill Oil can cause sloppy poos in some dogs, fish/krill oil its excellent for dogs skin/coat..
