My Gracie doesn't "cramp up" but she will run full speed in the yard and come in the house limping.
Less and less the limping did not go away after a day. Last year the vet manipulated her front legs and could not find any tender areas, but he gave her a steroid shot that helped for a while.
She limps nearly all the time now. Just a little, just her front leg. No corns. When she had her dental the other week the vet xrayed and found osteophytes-evidence of bursitis. We are to give her Tramadol as needed.
