Hi, My name is devrie. My dog Maximus is a very active 10 1/2 month old. I just found your site and I am now a little concerned. Our local vet has been encourage us to run and or walk him everyday to help with energy. They also encouraged us to get him neutered at 6 months. I have been running him for the last month about 2-3 miles 2-3times per week. Is this bad? What did I ruin by doing this?
