This might sound like a stupid question, but I've never had a puppy. Remi is now getting to that age (13 weeks/ 14 as of tomorrow) where he jumps up and down all the time, including off the furniture. I know this is bad for their bones, and was wondering if jumping of the couch or bed will hurt his bones in the future. I read that their suppose to wait until a year before any kind of jumping for agility and such is done, so does that mean that I need to watch everything he does so he doesn't jump off any furniture. Or is it okay to let him jump off stuff?
