3.5 month old lab plays too aggresive
Our new pup is still trying to adapt to home living. The breeder kept him in a large pen with several pups from other litters. He recently has become very aggressive towards me and my wife while playing. When on the floor in the house or even in the grass outside, he will suddenly leap at our face. Prior to his leap he shows no sign of hyperness or aggression.
What is a good way to break him of this behavior? My wife wants to get a e-collar. I would rather figure out why he is doing this and change his behavior.
Any tips would be very much appreciated.
