my collie used to have problems and he's about the same weight...maybe a little more, but what we had to do was before he new what we were doing my sister and I would get him to lay down on one side. Then I think it'd be better to show >.<


my sister used to have to sit next to me with her legs over the other half of him and we just lean over him and get his nails that way. We would also give him a treat after every nail. Anyway, this way lets me decide how much pressure is needed to control him and as long as his legs don't get under him he can't try to stand up ^_^
