I got a puppy a couple months ago because my 10 month old German shepherd needed a friend. This girl was giving this white puppy away and she told me he is half husky, half white shepherd. Well he has grown like a weed. He is 4 months old now and his color has been rapidly changing. He has very different behavior from other dogs I have had. He's not good at listening, he will rip food out of my hand if im not paying attention, once he's drinking water or eating something he isn't supposed to its almost impossible to pull him away. My shepherd was the same as all puppies are but after this amount of time I feel this dog should be somewhat learning from me desperately trying to get him to obey by now. My shepherd is a saint! I'm just curious honestly at this point if he has some wolf hybrid in him so that I can do the proper research how to train him to listen to some commands. He's very close to me and loving (he will not cuddle though like my shepherd), but if we go to the dog park he hides between my legs when other dogs come around or people. He's only comfortable at home and I also have cats and he's very curious about them. He won't go by anyone he doesn't know. I'm attaching a picture of him. He is about 3.5 months old in this picture and my shepherd is nearly a year...any ideas?
