Remy just hit five months and it's like a switch flipped and he went into TURBO energy. He wants to GO and GO and GO. When I get home in the evening it is already dark so I am going to start taking him on longer walks every morning. Today I decided to walk him and see how long it took him to settle down and get a bit tired (a tired dog is a good dog!). We ended up walking 2 MILES! I'm fine with that as I've been wanting to get in shape anyway, but is that okay for him? It's a neighborhood and I try to allow him to walk on the grass 90% of the time but sometimes he does have to walk on pavement. I've read on the forum two conflicting views... one that you should walk them until they're tired, and one that you should walk 5 min x months old. This walk took us about an hour... so that would be too long? What are your thoughts?
