Although Rufus is my 3rd basset and 2nd I've had as a puppy, I've never encountered this before...He is shedding ridiculous amounts of fur (9 months). He looks like he has small chunks missing all over most of his back and flanks but it's not down to the skin. It actually looks like he's getting thinner, more coarse fur in its place. Do they "blow their coats"? I really don't want to take him in for unnecessary and costly tests if this is all it is.
