Odin is 4 1/2 months old. He is high energy. He gets 4 walks a day. 2 are an hour long and 2 are 1/2 hours. We play soccer or frisbee with him every evening for at least a half hour and play inside pretty much all day except when he is sleeping. I really can't imagine he could ever have a moment to be bored. The problem is he is nipping at my clothing and chewing at them too. He sometimes gets my skin in there and it really hurts. He seems to like that I say "ouch" when he bites because he will scrunch up his nose and do it more. I keep being told he will outgrow this. I'm afraid he might not. Did I mention he mostly does this to me?
