Aggressive Newfoundland Puppy
We have a 41/2 mos old newfy, she is our 3rd newf puppy and 4th newf over the past 24 years.
She can be very aggressive toward my husband and I. When the breeder was contacted about this early on her response was "she is more like her mother than we thought" and her mother was a "challenge" but thought this was due to the fact that she was an only puppy. Our puppy is one of 10. The mom lost a lot of weight and the pups were weened early and we got her at 9 weeks instead of the normal 12 weeks. When we went to see the pups at 6 weeks we did notice that the mom never interacted with them for the 2 hours we were there. It is a reputable and well known kennel/breeder in the newf "world".
She does her basic commands well; sits, down, stay. She is not food aggressive, you can take this out of her mouth including a marrow bone with no problem. She is good with other dogs, even knowing to stay low with dogs much smaller than she is. Behaves well with strangers and will sit or lie down if we have a conversation with someone while we are out. She has never shown any aggression toward anyone else besides my husband and myself.
She doesn't know how to play, playing with her 90% of the time turns into her "attacking" us. She will jump, grab our arm often not letting go. She has drawn blood through clothes and left many bruises. There are times when you can be doing nothing but standing still and she "attacks". In the backyard same thing happens. You can be tossing a toy or ball and after 4 or 5 times she ignores the toy and charges after us. If you stop the "attack" she will stand infront of you barking and nipping at your legs. Backing her up just makes her worse.
We have tried so many things and nothing seems to work. Holding her down makes her more aggressive. Putting her in her crate and ignoring her until she calms down works but it is now getting harder to get her to go in her crate.
She is a big puppy, weighing 65lbs and is very strong and powerful. We have even wondered if there is a mental problem. We have been told there is no such thing as an aggressive puppy, she's only a puppy and will grow out of it. Articles after article we have read seem to contradict each other. One of our newf puppies was headstrong but after a few corrections the behavior stopped. This one seems to go into her own world where nothing gets through to her. We are considering returning her to the breeder as having a full grown newf that is aggressive is not acceptable.
