The other day I noticed that while my golden, Casey, was around the house he went to not run but kinda fast walk to get one of his toys. I noticed that he was limping on his front left leg. The thing is he's not showing any signs of discomfort. He's still running around like a 2 year old, jumping on and off the couch and bed with no signs of problems. When he lays down for long periods of time he'll limp when he walks but after about 2 minutes of walking around it goes away. He is still limping when he runs and goes any faster then a walk, but like i said he doesn't seem to be in any pain. I moved his leg in different ways and put some pressure on his shoulder and all over his leg to see if I could get a reaction but I got nothing. The day before he started limping he was at the vet because he was obsessively licking his back right paw and would want to sit every few steps on his walk. The vet said it was a splinter and removed it and he's been fine ever since. We are on vacation in Pennsylvania at the moment but we are heading home tomorrow and plan on taking him to the vet ASAP. I was just wondering if anyone had any ideas on what it could be. Thank you in advance for your help!
