Letting a german shepherd puppy run with me?
I have a question about my 4 month old GSD puppy. I intend to take him rollerblading with me to have him "work" (pull me on the blades, run alongside me, etc) at some point in his life. He is currently training in basic obedience and is very good. He's also good with the blades (we went once or twice) and generally runs alongside me.
Here's my question:
I'm thinking I should avoid this strenuous exercise until his joints are fully developed but I wanted to know your opinion. Can I start him on that now? Just like until he gets tired and no more? I mean I understand they shouldn't be allowed to jump or do any agility due to their developing hips but what about running on a flat (although hard) surface? Is that ok?
Please let me know your opinion, I'd really appreciate it. We already go on walks (1.5 hours total per day) plus obedience training and games (fetch etc) but I really think something like this will help put his mind into a working mode and satisfy that need to work (by pulling me on command etc).
Thanks in advance!
