Yes it that time i have Siberian huskies at the end of summer and end of winter they blow their coat the house is a mess, our cloth are a mess, and thye are mess i am sure people think we do not care of them they way they look right now. It does come out easy but you could also use a shedding shampoo and a wonderful brush my new best friend the furminator it looks like a rack it does not have pointed tips and it is good for undercoat.
Yes it sounds like that.
Some dogs (very much like wolves) have two layers of fur, the under-layer, and the top layer -the 'guard' hairs. When the under layer starts to moult, they can look quite a mess! If left it can form something similar to "dreadlocks" and get into such a tangle. It's better to take it off by gentle pulling. It will come away quite easily. Then comb the fur.
