Diet could be definitely the cause i would try that, before following the vet. Because most puppy food, is made with chicken. Which is the most common sensitivity. And you don’t have to feed puppy food because its for puppy’s, the only thing you should avoid is the ones that say adult food. So a good food to go for, is grain free, high quality meat, no mysterious meat, no colouring, no starch. Most of the time vet tests come up negative or inconclusive. Also, sometimes it is the way the food is processed in dry food that your dog can react to. In which case, try raw, it is more expensive, but it is fantastic. Vets go against it because they get a day training of nutrition provided from the big company brands at the vet. And they have to meet a quota each month as well.. Id say try raw and if you are worried that it is not nutrionally balance (because all vets will tell you different), get nupro gold, it has all the vitamins a dog needs.
