I just got this puppy. He is 3 months old. I got him from a family that left him outside all the time, and the old owner had two daughters that would play with him, but it was more like teasing. (I dont think he got much love) He is very loving, and I know he is teething some, but when we play, he bites. Not to be mean, he is just playing. But he has broken the skin in a few places, my nose, my hand, my arm etc.. I've only had him a couple of days, but will this get better as I work with him?
My Bearded Collie dog does this too. It doesn't do it much to me anymore but it does to my father (since he doesn't take care of it properly.. I guess.) But I've been working with it until now. Sometimes it does it and some times doesn't so I'm still working to get the problem fixed.. Work with it early. If you do it later, it'll get worst.
Animals have it's own personality, you just have to find it.
We had the same problem when we adopted our 3 month old puppy. She kept biting at my teenage daughter, thinking she was a littermate. She was playing but it hurt her with those sharp little puppy teeth! She didn't do it to my husband and me. We tried EVERYTHING! I talked to a trainer at PetSmart about it. He said to take an empty soda can. Put some coins in it about 1/4 full and tape up the opening with duct tape. When the puppy started to bite my daughter, she yelled "NO!" and shook the can twice. It worked like a charm! He said the person who is getting bit must be the one to use the can. Our lives are peaceful now! No more biting! YAY!
I grab their whiskers or hairs on the side of their nose and look them eye to eye, nose to nose and say "no" firmly. I generally only have to do this for a few days and they stop.
I don't snap their noses, as their noses are very sensitive. A hard whack on the nose can make a dog lose their sense of smell, so I do the whining myself, like I am hurt, or grab their whiskers and discipline them verbally. It works for me.
He is your friend, partner, defender, your dog. You are his life, love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
