Hello! I am new to this site I have 2 dogs, one a 6 year old GSD/Belgian Mal. female, and brand new 13 week old (full bred) GSD puppy... Molly is the girl, and Ferguson is the male.. they both LOVE each other, and sleep together at night and at nap times...they play, but.. Ferguson, my full bred GSD, plays way to hard with Molly.. he bites her, neck, ears, legs, etc.. draws blood :/ and she has not corrected him with any snaps/bites back.. he is almost half her size, maybe a little more.. and he is growing fast. I have been working on bite inhibition, and he has been getting better with humans, but with Molly, he hasn't stopped being so rough.. she has been too gentle with him? I will be taking Fergus to puppy kindergarten this week, any tips ?
