Getting reliable training in the last three months has been terrible. In between club politics and the weather (there has been ice on our training field for the last 3 weeks, so no practice), so I've been to Bob's club twice. Anyways, it seems Zoso is not biting as hard as he probably could. I wondered about this and noticed that after most sessions, even with a soft tug, there might be a little drop of blood or three on the tug. He gets ester C supplements 1-2 times a week, fish oil and vitamin E supplements every day, and he's on the raw diet (mostly chicken quarters, pork necks, sardines, raw eggs, etc). I only started playing tug with him at 16 months and he is 24 months now. Any ideas on why he might have a soft mouth? Is this something that will improve at all? Should I have him checked out for dental issues?
