We have a gorgeous six month old long coat male puppy named Max.
He is potty trained, knows and obeys most commands, has been for his vet check up today, and has a clean bill of health.
He was very well behaved, until about 2 weeks ago.
He is starting to show aggression towards me when I tell him "no" - like when he is digging holes in the garden, or chewing something he is not supposed to. He will start by giving a series of very high pitched barks, while continuing the naughty behavior. When I tell him "no" again, he lunges at me - grabs a hold of my hand and growls. When I turn my back on him, he bites my legs or jumps on me. The only way for it to stop is if I remove myself to another room or put him outside. Redirecting sometimes help, but I don't always have a toy or ball in reach.
Also, when I am lying on the couch or in bed, he will jump on me and start biting my hand. It seems like it starts out as a game for him, but it soon changes into him biting really hard and growling.
This is something completely new - he has never done this before.
He only does this with me, and not my husband.
I do most of the training and disciplining, and spend the most time with him, but it seems like he sees my husband as the alpha and tries to dominate me.
I am really at my wits end. I do not want to be scared of my own dog, but he already weighs 34 kilograms, is very big for his age and starting to become very strong.
I would love to stop this behavior as soon as possible, before it becomes a real aggression problem.
