It's very common for dogs to get those behind the ears. Depending on how bad it is, it's usually too difficult to brush it out. You may be able to cut it out with scissors, but be VERY careful. The skin back there is very tender, and usually those mats are so tight it's really hard to tell between skin and fur....somebody once brought in an aussie...they tried to cut one of those out behind it's ear and ended up cutting him really bad where he needed stitches.

Try to loosen it up as much as possible with a comb, if you feel like it's far enough away from the skin, I would cut it with scissors. Sometimes it works well if you cut the mat in half. If not, I'd take him to a groomer and see if they could just shave that out for you.


Sheltie and Collie hair is diferent from regular dog hair, if they get cut, there hair grows back abnormaly, thats why you really shouldnt cut it and you have to be careful..
Very true, I'd never recommend shaving the dog entirely, but it's common to have to shave behind the ears and I think it'd grow back just fine.
