My dog has been on this food for almost a month. She was diagnosed with HUU. She loves the food and treats.

This was prescribed to my mastiff pup around the 10 month mark. He does not digest rich foods well (no specific food allergies but anything other than a 'bland' diet seems to give him the runs, just a sensitive tummy) and he does have environmental / skin allergies. He LOVES this food, and in my opinion it does not smell strongly of eggs like I had been warned (the smell is about as strong as any other dry dog food i've smelled), and not offensive in the least. He also began cytopoint shots around the same time so after his bday we plan to take him OFF the shots and just let him ride on the food and see how well he does with the itching and pink skin since the vet had said it takes a few months to build up that barrier for him. Worst case we will combine this with the apoquel daily pill if the food is not enough, but i'm confident that it is helping regardless. Depending on the severity of each specific pup's allergies it may very well do the job on it's own, but in combination with other items it goes a long way to help. I am satisfied with it.
