Hi there, I have a beautiful 10monthold GoldenDoodle who is apparently allergic to meat. So I have switched his dog food but yet he still has itchy skin and I felt he lost a lot of his energy from having not enough protein, so I switched his food again to the flavour Salmon & potato, but yet he still has itchy skin, what do you recommend?

Seeing the vet. Itchy skin is a symptom, not a disease. It could be allergies (which could be to a host of things, not just food), it could be fleas, it could be mange, it could be an autoimmune response, it could be too much bathing... Find out what you need to treat and solve that, rather than taking a shotgun approach to the problem.
