<human>: Last week my dog cut his paw on something so he has been on R&R for the last few days to prevent it from reopening. 

He's a one year old huntaway x lab and full of energy so he's not liking the R&R to much, in the last couple of days we have noticed he yelps when you try to roll him on his back from a sitting position. 

The other night my partner said he was patting him on the couch and he just yelped in pain and couldn't put weight on his right front foot for a couple of min, after he came right he was running around like a lunatic like he always does. We can play rough with him push him, he jumps around no worries but as soon as you roll him onto his back he yelps. 

We are stumped as to what's wrong you can push down on his shoulder,back and he's fine with it. We are going to give him another week of doing nothing if he still yelps when rolled on to his back he will go to the vet. But has anyone had anything like this happen to their pup?

Summarize the given text in a few sentences.
<bot>: my dog can rough house jump around like a lunatic run around but if you ask him to sit and try roll him onto his back he yelps in pain. Which he never use to do.
