Yes knots behind the ears can be a hugeproblem. I tease them out when they happen. Ears are the worst part of the whole coat, the rest is quite easy!
I try that but sometimes have to resort to scissors! I hate to do that - it gets so curly someone actually asked me if I'd crinkled it!
i found a brilliant comb that teases the knots without pulling. it has smaller teeth and longer ones.;-)
this is the one i have http://compare.ebay.co.uk/like/1608...ixedPriceItemTypes&var=sbar&adtype=pla&crdt=0
I love rough collies, there is a 14 year old gentleman we see on our walks regularly. He's such a clever gentle lad and gets on really well with our two.
