Oh no I'm sorry you're hurting like. I know 2nd hand how that goes. My dad had surgery but still went on to make sure our Beagle mix got walked...lol

I am having Knee surgery in the next 2-5 years to replace the non-existent cartiledge there. I'll have a mutt, a pom, a Samoyed, and a Dobermann to contend with! lol Its worth the pain in my eyes XD

You could try letting your dog chase a laser pointer light around for a bit, that worked when I was in wheelchair with my Dobermann
