Well, Pedigree is not a very good food. You might try Pro Plan salmon food.
Is he on thyroid meds? It might be a good idea to have a T-3, T-4 rerun.
Bathing once a week seems like a lot. Bathing too often can actually strip the natural oils. Try a mild oatmeal shampoo. If this has been going on for a while, getting a skin scraping don may be a good idea.
hey
he is a labrador, 7 years of age, and yes he has some kind of red rashes on his body. he bathes after every 7 days. he eats pedigree. and he has thyroid too.
My first question is, what food are you feeding? What breed of dog and how old? Hiw often are you bathing? Do you see any skin irritation like red scaly patches or bleeding?
I have heard that you can use human dandruff shampoo on them
