agree..its hard thing to see them suffer once CAE begins to show its self...in the mean time until you know..you can give her a daily aspirin, add flax seed and MSM to her feed ration..to help with inflamation...cool water run help reduce heat and swelling..just let a hose run over her knees..
flax at the grocery store...in the baking isle
MSM is for horses..Tractor supply carries it as will any horse supply store
I agree, I would test her for CAE and go from there. If she is arthritic and in pain the best thing would be to put her in the freezer (or just put her to sleep if you don't want to eat her). Also wouldn't hurt to look at her feet, if her hooves are overgrown it could cause her to be walking differently and add more strain to her knees/legs.
