6-1/2 mo old Cavalier Bentley has been with us now 2-1/2 weeks, still with breeder when we got him and was not a house dog. potty training was perfect until tonight. i waited too long to take him out. He has a very soft 50x60 inch throw I bought for him which he loves. He scratched and made a nest like circle out of it, then peed on it tonight. I told him no and took him outside then washed the blanket so it doesnt have a pee smell on it. he has never gone in the house before so I know this was my negligence and he has gone potty outside several times since. What I was wondering was why he made a nest out of his blanket before he squatted on it? hoping that was an isolated incident.

never saw a dog do that before.
