I have to say....in no defense of this guy. With Joe who is my German Shepard mix...who I think is 90% GS. When he was a puppy and up to about 7 months old he would snap at my son. We did roll him over...very gentally and I had Tristen put his hand on his lower stomach and a hand gentally on his neck and stare in his eyes and say no. This was not a mean thing and we were very gental with him. It took about 6 times doing this right after he snapped at my son. He has never ever done it since. Now with that being said....again it was not a rough thing....we did not hold his neck tight at all...it was a gental hand. Afterwards he was rewarded and loved on by Tristen.
We tend to be very gental with our animals as I believe if you train them roughly....they will just be scared of you. I hate to see animals that look scared of their owners. Just today we were outside and apparently the neighbors dog pee'd in the house. I think he must of hit the dog a few times because he was screaming and the dog was yelping. It was terrible and my GS almost hopped the fence and went after the guy. Again....I am not a training person.....I don't train my dogs much. (Bad me)....but I do have faithful dogs that would not stand for anyone coming in and hurting us...and they are super happy carefree paw paws.
