Need help with puppy!
Me and my husband recently got a puppy. When we went to look at it, we knew the previous owner was horrible. The Jack Russell puppy was stained yellow with urine, its white skin was black (100% covered in fleas) and its tail was broken. When we asked about the fleas, she stated that she had tried to get rid of them once, but did not have any luck so she did not try again. She also has no idea on how the puppies tail was broken.We took the puppy home, because we could not leave it there in those conditions.
Once at home we realized the 16 week old puppy, was actually 13 weeks and the first owner sold it when it was 4 weeks old. The puppy also has a habit of fear biting/nipping. I know nipping is normal puppy behavior, but fear biting is not. My 11 month old son can crawl next to the puppy, and he'll growl and then bite him. I took him outside, and he started to growl at another dog. When I tried to bring him back in, he started to growl at me and then bit me in the ankle.
Everything I have tried is seeming to not work. We tried the spray bottle, the yelping and saying NO BITE, putting him in his kennel, ignoring him, giving him something else to chew on, and nothing seems to work. We don't want to have to send him to another home, but he's getting way to much for us to handle and my sons terrified of him!
Any tips or suggestions would be greatly helpful!
