He's definitely feeling better. His perky, pesky personality is back lol. I didn't even realize he was acting different until today. A friend of mine suggested having a chiropractor look at him since this could be a back issue as well. I'm in the process of trying to find one.... I hate moving!! I miss all my old equine contacts lol. I'm just glad my farrier is willing to travel so far to keep trimming him. :)
Anyway one reason I know he was feeling better is because he was galloping around and doing his floaty trot this evening. :D Yay! His stifle stills locks occasionally, but it doesn't seem as sticky as the past three days. Since he was trotting fine today I'm going to start his Couch to 5k tomorrow again. I've decided I'm going to go out and walk him twice a day for at least ten minutes even on his days off since he's not moving around as much as he did on the thirty acres. Keeping him moving seems to be making the biggest difference. Hopefully with these stifle strengthening exercises I'll be able to prevent this getting so bad again. I have several other exercises to try, but I'll share them later when I can get pictures or video.
Thank you everyone for your support and advice. I was feeling really sad about all of this coming back, but you guys helped to make me feel better. I'm so happy to have all of my blogging buddies. Night everyone!
