my boy is slightly matted on the tail and backside. it's pretty easy to brush out and pull out, but I suppose he doesn't like it because he tries to chew on me or the brush making it almost impossible. Any tips on coercing him to allow me to do it would be welcome!

have you tried keeping him occupied with treats or a toy while brushing him out?

Try giving him a frozen marrow bone to chew on. Something that will occupy his mind while you're brushing him out.

What brush are u using back there? I find the rake with wide teeth to be the best. I try to get them after a walk or I stradel them squeez my legs a bit by he hips to keep them from moving tha pull up the tail to get the back side.

good tip on trying the marrow bone...he loves em!

the brush I am using is a single row undercoat rake:

Sometimes mine get antsy when i'm brushing too hard (esp with the undercoat rakes- the pins can cause an uncomfortable feeling if pressed too hard) so i'll back off pressure wise and they're usually fine then.

When I brush back there my dogs are usually lying down, that makes it easier as well as easier to distract them with a bone or whatever if need be.
