I have a really high energy lab who is pretty destructive and just insane without being able to get his energy out outside. Right now the weather is super cold (-40s F) and so we only have the ability to take him potty before he has to come in. We do lots of puzzles and mental games to some energy out but it's not working as well as I hoped. I need any ideas on ways to get energy out inside. We have tile so no indoor fetch and he's like a bull in a china shop.
