Hello. Glad to be in the Chi community. I need help with a chi pupoy, 12 weeks old, who is a little terror. I have had him for 3 weeks. I have had a Chihuahua puppy before, but don't remember this crazy behavior. He bites and snarls and growls. Constantly. I know he is playing but if I correct him, he just gets more aggressive and barks and lunges at me. He is very sweet and cuddly when he wants to go to sleep, but I have never even been able to just sit and pet him, because he is always biting. He has a lot of toys, I am trying to train him with treats, I put him down on the floor, and try to ignore him, and I've tried using a sharp squeal when he bites. Is he going to grow out of this? I'm worried because I have 5 grandchildren and the oldest is 5. He is wearing me out. He is also terrorizing my German shepherd who has the patience of a saint, but I can tell his patience is growing thin. I need help. I am 67 years old and have had many puppies throughout the years but have never experienced this before. Thank you.
