I have a blue staffie with skin condition. She is too young to get tested for allergy. The vet recommended hypoallergenic Royal Canin but I could not see any difference on my dog. I have swiched to Fish4dogs puppy food and she is so much better. There is a bit of scratching but it is at a normal level. I also have a 3 year old staffie x husky with arthritis. After 3 surgeries, he still surffers from his legs. Fish4dogs has helps and he loves it. Delivery is prompt. Good quality food. I would recommend anybody to give Fish4dogs. My dogs have a better diet than my kids!
