My 9 month old dog has bi-lateral hip dysplasia so she's very limited in the work she can do. No intense things like agility, flyball or running hard. Her walks are limited to about 10-15 minutes and are not too strenuous. She's an aussie cross and is a very energetic dog. She's been great with the limitations so far but somedays she just can't sit still for too long and I feel pretty bad as she just wants to run, run, run. Occasionally I'll take her to a park or the farm and just let her goof around and enjoy herself (then gets metacam to keep her comfortable) but I can only do that occasionally as it's nice to just let her be a dog. In the house we'll toss/roll the ball around for her to grab and since it's not a huge house, she can't run hard/fast but enough to get some energy out both mentally and physically. Tug o war is another game she loves, and we also keep her occupied with bottles to whack around/gnaw on. But I'd love to have some extra exercises to mix things up with her. We're going to start consistent swimming activities soon, but the more suggestions the better! As a note; She's on 500mg of glucosamine twice a day and is looking/feeling very good. You wouldn't know she had an issue except for a slight hitch in her step, but that is more due to when she broke her leg at 4 months old.
