I have a German Shepard, who was said to be part husky. He is a little smaller, but looks like a GSD. Anyway, he is a great dog, loving, and very obedient. He only went in to the bathroom in the house once (he was very young, and we had to give him electrolyte water), rarely has to be told something twice, and never needs tied, as he just stays in the yard. He is great with the chickens, and loves babysitting the chicks. At night when one of the hens doesnt make it to the chicken house, he stays outside to keep watch. I dont know what I would do without him. He also, has a great nose, and loves to find people. My mom took him to search and rescue practice, and he was great.
But, I did take him out a lot as a puppy. Wherever, we went he went. And I noticed that he was afraid of nearly anything. Shake a bag in his direction, and there was a puddle on the floor. And forget swimming, he thought he was going to die. It took a lot of work, and encouragement to get him where he is. It wasnt because he was bad, or ignorant, he loves to please. It was because he was so afraid. And fear can cause an animal to do things we dont want. I have heard that many GSD are fearful, not sure how true this is.
He did kill two chickens in his youth. One was an accident while he was rounding them up (following in our border collies habits) and the other wasnt. After me yelling at him for killing my baby, and not being able to look, and pet him for a few days, he decided that he loved chickens.
I do believe there are bad dogs out there, but most of them just are victim to bad training. Spend time to raise your girl right, and you should have a great dog. I would say the most failing thing a person can do when raising a dog, is let them get away with not doing something, or punishing them for something incorrectly.
Example 1: Someone tells dog to sit. Dog doesnt sit. Person just goes on with life. This is teaching the dog to ignore their request. Push that dogs but down, and say "this", pat on head.
Example 2: Someone tells dog to come. Dog doesnt come at first. Tell dog to come again. Dog comes, and they smack it. I only smack my dog in this instance if I have to go get him, if he comes to me he is good, and gets pet. Also another example of this is if a puppy is chewing on your shoe, it is common to just yell at him. But, after yelling at him it is a good idea to find a toy that he can chew up, putting it in his mouth, and saying "this", so he learns that chewing isn't bad, as long as it is his toy. And make sure you let him know what toys are his. I did this by putting his toys on his blanket, and telling him that it was his.
Good luck,
