So my yellow lab, Buckley, just turned 6, hes right around 100 lbs and was hit by a car when he was maybe 1 year old. Hes got a plate in his right leg with 6 screws in it. But today when we went to the park and he did his run around he darted out of the car towards another dog. Later in the night he got up and was limping on it and trying not to put an ounce of pressure on it. Even later he went out for his final walk of the night and seemed to be walking pretty decent. He laid down for a little while i watched tv and than he got up and once again limped and couldnt get up the steps. If hes not ok in the morning ill definitlyy worry even more. But even if its just a tonight thing think its anything to worry about? Like maybe was it a pulled muscle or is it something should be worried about for future reference considering its the bad leg?
