Weims are awesome dogs. Ours is 5 yrs old and is just as crazy now as he was when he was 6 months old. They are very challenging, but I couldnt ask for a more loyal dog. Good for you for taking him in. A lot of people give up and abandon or abuse weims. They are one of the most intelligent, but one of the most difficult. A lot of people dont realize how hard it can be. There were many times my wife and I wanted to give up, but we stuck with him. Here's a picture of him. He's one the bigger ones Ive seen at 95lbs
