I've had Walter for about a year and a half now. He was fostered in a prison, and the prisoner noted several times that Walter LOVES having his chin scratched and it always seems to be itchy.
He came to me on Purina Pro Plan and I changed him to Orijen (http://www.orijen.ca/) because I wanted him to be on a better quality dog food. After a few months on Orijen, a bout with worms and way too many mushy poos, I switched him to Acana (http://www.acana.com/products) which had less protein, so I thought his poos would get better. They did(not perfect but definitely better). For about the past year he has been on the Classic and Regional varieties of Acana. He is rubbing part of his lip fuzz off, he rubs his nose so hard that he gives himself rug burn and I muzzle him when I leave for work because I don't want his scratching/rubbing while I'm gone.
Now I have him on Acana Singles, which is a single source protein food.
I want him to be on a good, quality food, but I don't want him to constantly be so itchy. I'm not sure what else to do.
