7 year old Zeus, beautiful Black and Tan German shepherd. He was my son’s dog. He is not able to take care of him. I took him so he wouldn’t go to shelter. He’s a very sweet dog, but weighs 90 pounds. So he’s more than I can handle. I live in a 25 ft camper. I’m not able to walk him due to injured shoulder. However he needs a spacious fenced yard to run. He’s completely potty trained and would not ever go to the bathroom inside. He is neutered. Although bred with a champion German shepherd, he showed evidence of hip dysplasia. He loves to play with empty plastic bottles, and he has one special rock. He entertains himself most of the day chasing shadows and bugs. He is good with other small dogs. If a bigger dog approaches him he would become aggressive. He’s excitable and doesn’t always pay attention to what’s around him. Firm voice with command he will follow. For further quesyton
