I definitely think that every puppy is different and everyone’s puppy training experience is different. I’ll be the first to admit that I tend to form bad habits with my dogs. Ie, letting them sleep with us, run the house, etc. We just got a 12 week old yorkie male, and I can already tell he is going to be completely different to train than our 7 year old female yorkie was. He’s a little biting ball of energy. I don’t necessarily think he is too much for you. I just don’t think you have found your grove yet with him. You’ve got this. The training will definitely help. Don’t give up yet.
