Maple had dry skin and dandruff the vet suggested putting a little bit of olive oil in her food so we've been doing that for several weeks and the dandruff is gone. Also I remember reading on here that an egg is good so she gets a raw egg in her food once a week instead of olive oil, and a lot of people seem to be using fish oil to help with dry skin too.... I'm sure someone with more info will chime in, hope your baby gets better
I agree with Maple...adding some oils fish/salmon or omega3,6,9 would help. Also try not to bath Rock too often, Boxers are naturally a very clean breed, so only once every couple of months will do. We use aloe baby wipes in between baths if needed. Hope his dry skin clears up soon!
I have heard that Vitamin E Oil is good for the skin. I know someone that used carmex for the sores in the paws from cold weather, so I would imagine it would be OK around the mouth. She said the dogs didn't like the taste of carmex so they didn't lick it off their feet.
