Over the past few days Triley has developed a number of bumps/clumps on his skin. They are almost like scabs but there is no blood, just dried skin and hair. I've picked some off him (he doesn't seem to mind) and it is just a clump of dead skin and hair - with some tender skin left behind. I've never had a breed that sheds and I am wondering if this is just some strange (and obvious?) part of the shedding process (a blow coat?) or if he managed to pick up some skin issue at doggie day care? Help!
