We have a year old 80 lb shepherd(our first) named Max. He refused to sleep in his crate at about six months old. We have two inside cats that were not quite as happy with our puppy as we were. So luckily it was April and we had a fenced area with a house in it. We have always walked him 3x a day and spent time with him several hours a day and he comes in the house & workshop several hours in the evening, but he is always ready to go back outside by 8 pm. He is a wonderful dog. What I need is some suggestions about how to help him relax in the house. He has toys...he likes balls best. He seems to walk around almost non stop. He is an avid chewer so we do have some chew things available but he doesnt stay put long. The cats are in another room so he is not restricted to any one area. He is very well behaved.
