ohhhhhhhh, lol, then yes, you could very well be entering "blowing coat" .. where they are growing thier adult coat and the puppy coat gets tangled with the incoming new hair...
The matts can form right before your eyes it seems!! At the worst of it, I was spending 3 hrs a day combing her ... finally I decided to have her shaved down because she was starting to become afraid and wouldn't come to me!
Shaving her down gave us both the break we NEEDED, saved our relationship and then we started from square 1 combing her out every day as her coat grew out.
Some don't blow coat quite as bad... but some do. BUT hair will always grow back.
