My boy had the strangest walk as I was leading him into the indoor. Flapping his tail and taking either weird high steps outward, or dragging his toes as he walked forward. In both the hind legs. I immediately pulled him back to his stall, took off his tack and went to ask my BO. As we walked around the property, her opinion was of 2 minds. It had been a colder night than usual, and possibly he'd gotten stiffer than usual in his hind so his walk was off. Her second thought was that it was an 'irritated' walk especially with the tail flapping around, as in there was an itch he couldn't reach. I took her advice to saddle him up and walk him around, do some light trotting, and see how he felt.
But first, I led him into the arena and let him roll, which he did with gusto, even rolling over from one side to the other (something I had not seen him do yet).
Got up, shook, then trotted down the long side, pooped, and spooked and galloped up toward me. Long story short, we had a pleasant ride and it seemed he was back to normal. My question is, how can you tell the difference between an irritated walk and a 'off' walk?
One other comment: the last time I cleaned his sheath he walked funny like that!
