He looks great…and happy. Remarkable for all the changes he’s experienced in…what…4 months since he left the track? Active race horses lead rather solitary lives, there are horses around them but no socializing. Every minute is planned, no free time to play in the sun and muddy rolls. He is making his first friends in 4 years and relearning herd dynamics and making his own choices when to graze, when to play and when to socialize, even mutual grooming. Huge changes for him.
To me, he looks much more comfortable then he did even a week ago. His posture tells me that body soreness and stiffness is disappearing and I bet his feet are bothering him less.
IIWM, I’d leave his feet be, just let him move on and let things work themselves out. Don’t waste products in the mud and don’t think he needs boots for pasture and very light riding on soft ground, if they would even stay on. Just let that be.
With so many changes, not surprised he might be anxious when bitted, actually would expect it. But its not hurting a thing if he wants to fool with the bit at this point, no wonder, in the past the bit has meant hard work and maybe excitement ahead. Messing with the bit can also mean boredom, it sure bugs us but don’t see an immediate need to start switching bits around, little early for that, IMO. All in good time. As he relaxes, many things will change and you are only two weeks in. Patience.
