Pitts - thanks for sharing this info. I nearly fall out of my chair when I read those post that say "MY puppy is aggressive - I need help" People buy a dog that is a dominant breed and then expect it to behave like a lab. I call them labs in dobe suits. This is incorrect temperament. I try to explain that it is a BABY not a dangerous dog. A BABY that has to learn the rules and who is top dog. I hope all new puppy owners read your post 10 times. Gosh I would worry if my puppies did not growl and nip at this age.
I have had 7 Dobermans in my life, and this is the first for me in this type of behavior.
I also have a Golden Retriever in my home. The puppy is biting him bad!!! He has marks on his neck that is requiring antibiotics. This puppy is 4 months old.
I have used the method of grabbing by the scruff and using the word NO firmly, and he keeps coming at me.
This is not just biting. He runs at me not growling but barking at snapping at me. He does connect with some of the bites. What he is doing is demanding my attention when my golden gets his bone, or takes the ball outside, or he wants up in my chair with me, or he wants me to figure out what he wants, and when I don't figure it out quick enough he starts charging me barking and lunging with snapping jaws. And just yesterday he decided to go potty in my van when I was driving and couldn't stop to attend to his barking as he wanted. He also repeated this act last night again on his dog pillow when he wanted something that I didn't give him my attention on. This puppy has a dog door and knows how to use it. He has been house trained since the first week of owning him. Before I gave him the dog door to use; he went to the back door and wimpered.
Nobody can give this little guy a hug, or a good petting without his teeth. When company comes over we put on his leash to keep him from biting them.
No matter how many time I grab him by the scruff, he keeps coming at me.
I would take any suggestions.
