Yesterday, we went to Alafia River State Park, one of our favorite places to ride. The day started off well enough but it was soon obvious that Cody wasn't himself. His stifle locked a few times but he worked that out and the more active he is, the less it hitches.
He dragged along at the back of the pack... behind T even. Which is pretty unheard of for Cody. He prefers the front, though he'll settle for the middle, but he's never content to be last. He was slow moving, sweating heavily, walking with his head lower than usual and just plain unhappy.
Also the small "lump" on his lumbar (noticed it after Tillis Hills this year) is inflamed and tender.
Time for the vet.
