salty, most of time its waste of your money to go to vet for limp..i used to give my beagles a baby aspirin back in 60s..they would limp sometimes for 2 days ,then disappear and it would come back again..mostly this was with older dogs..

i have dog right now that his joints CLICK and snap..you should hear it..somedays it real bad,others nothing..vet said,NOTHING I CAN DO ABOUT IT..

my sister had dog that was old,it would fall down and throw up every once in awhile..i said, SIS, DOG IS READY TO DIE..she got mad at me and said, what do you know..

well, she went to vet and bill was over 600 dollars..i said, whatttttttttttt..

then vet said, make him comfortable, he has cancer,duhhhhhh..

ANYHOW, i would be concerned if dog limped for a week, but just for a few days,no way..this is only my opinion,not saying you are wrong on going to vet..
