Hi all, I am new to this forum but not a new dog owner. I have had dogs/puppies all my life and recently lost my Bullmastiff at the age of 10. A week ago we got a new puppy, he is very playful and nippy like all puppies. However I have some concerns that he may be showing signs of aggression that is beyond just regular puppy play. He seems to be very obsessed with nipping one of our 3 children. Today for example we were walking in the hallway and the pup went by me without acknowledging my presence and jumped straight up to nip on my toddlers leg. He then wouldn't let go of his trouser leg I had to literally drag him off. Also today he was chewing at furniture so I removed him he then snarled and bit my finger. My partner was in the garden with him and he was tugging at her trouser leg so she removed him, he snarled and launched at her and bit her leg, she removed him again and he repeated this. A few minutes ago my partner was on the floor playing with the pup and his toys and he then turned his attention to the sleeve on her arm, she removed him from that and once again he snarled and tried to bite. That's 4 times he has done that just today. He is 9 weeks old, has loads of toys is literally never alone as both myself and partner work from home. Aggression or playfulness? Your opinions please. I don't want to risk an aggressive dog around my kids.
