He is a 15 month old Brat. I adopted him at 4 months old. He is very active as he should be as a puppy. I walk a lot in the woods, he has hiked long distance 12- 15 miles. He is very lovable, sweet, but can also be a little rough with my young female cat, the older cat keeps him in his place.After 3 months of obedience he is doing well if I keep at it. We have also done some Agility that he is very good at. He is quiet for the most part but have also worked with him on this. He is wonderful.
