I am not qualified to comment on the subject. Me and Mrs Pute have had nothing but Pomeranian's for the last 30 years. She loves the breed and I just tag along. I let her have her dogs and she lets me go fishing....Now I hardly fish and she has cats......there are no bad dogs, just bad owners teaching their dogs everything but love...dogs are like kids, teach them love and kindness and that's what you get...I know someone that has scrawny fear biting GSD's...to teach that aggression they beat the dogs so they lose all confidence and bite out of instinct...these people and dogs need put down...you hit a dog you should go to hell...
