After I got him back from a boarding place yesterday where he stayed for 10 days, while we were on vacation, I took him to a field for a run for about 1/2 an hour, than we got home he rested a bit than I took him for a walk for about an hour. Could not notice any limping whatsoever.
When I gave him something to eat I notice he is barely puting any weight on the rear right leg. Sometimes he would even keep it slightly of the ground.
He would still walk and run and does not limp, but when he is standing he is letting go of the weight from that leg. Also I noticed while laying down on the side he would move that leg fast; I knew it was bothering him.
My doubts are that he injured hopefully just a muscle in the leg either while he was boarding or after boarding when I took him for a run on a big field.
Any advice would be greatly appreciatted, (before I take him to the vet).
If you haven't already, check his foot to make sure there isn't a burr or something stuck up in it. When my dog got something in her foot, she would shake her leg a lot, like she was trying to shake out whatever was stuck.
