Prescription Diet

My cocker spaniel has severe skin allergies so I'm trying this prescription diet and she loves it, but have only been feeding her for about a week without her old food mixed in, so not sure how good it's working yet. She's still scratching, but hopefully that will stop or at least get not so bad with this new diet.

Best Food For Allergies

My German Shepard has the WORST allergies and I tried every single brand of food out there. But after the vet recommended this food, we tried it and it has worked amazingly! No more hot spots, itching or bleeding!! Her coat also looks the best it ever has!

Good for food allergies

I had an extremely difficult time finding a food my bully could tolerate that didn’t cause skin reactions. This product seems to be delivering as promised.

tried And didn’t like

Was told by vet to give it a try since my boxer has bad seasonal Allergies. He has been on raw diet which he enjoys but was looking for something to help with skin. I gradually added to his raw and he ate and seemed to take to it. But by week 3 doesn’t want it I tried 50/50 75/25 etc. he would eat raw and leave or spit out the kibble and when I crushed the kibble on the raw he lick it and leave it . Im not saying it’s not a good product. But if ur transitioning maybe buy the small bag just in case. I bought big one and now left with half a bag.

He has stopped itching

My Chihuahua has had really bad itching for the past 3 years. He also has a very tender stomach. We tried Hills Science diet (skin and sensitive stomach), and several Hills Prescription diet foods; Derm Çomplete, z/d and didn't notice any improvement. Then we tried the d/d and he loves the flavors and after a few weeks, we noticed he is hardly itching at all! He likes the duck as well as the salmon flavor, and licks the bowl clean every meal.
