Today, after I finished barn chores, I was watching him stand under his favorite tree. Beautiful weather, cold but sunny, no breeze. He started to lay down and stayed in sternal recumbency under the tree, ears erect, just kind of looking around. Of course my stomach lurched and I held my breath to see what his next move might be. This is a horse who NEVER lays down except to roll and get back up immediately. After a few minutes, he got up without effort, and flexed each hind leg as if to get the kinks out. Then he walked to his water trough for a drink.
I'm familiar with the typical issues facing older horses (tooth wear, less effective body temperature regulation, etc.), but I worry that I'll miss something taking place in my guy that might be critical. The most obvious age-related change I can see, other than appearance, are his vaccination reactions, despite staggering them weeks apart, and pre-medicating him.
I'd appreciate hearing feedback about your oldsters and the mental/physical changes they've shown and any advice you can impart. Just feeling nervous!
