Yepper, very familiar with the butt problem. Poor Toby when something gets stuck to his fur, just walks really slow (usually he runs like a speeding bullet) and stays in the humped position. When we see that, we know we are going to have to do the butt scrub. Fortunately I have a tub in the garage and it only takes a minute and all my "doggie" cleaning stuff is right next to the tub. We also have that problem with the Maltese on occasion.
