I have a question. Titan has started developing calluses on his front pads recently (I suspect it may have something to do with his weight distribution especially from that barrel chest of his) and I want to know what I can do about it. I'm a bit nervous of trimming them and what not. So what is the best course of action? Also the pads are incredibly rough, almost to the point where they draw blood when he climbs on my lap (he still thinks he's a puppy and that he WILL fit on my lap). It definitely isn't his nails, but the actually pad. I've never seen pads so rough. Could it be a feeding issue?
