Does your horse have a different personality in the winter?
I have a coming 5 year old Connemara X gelding who is the most chill guy starting in April. For the past 2 winters I've brought him to an Indoor for the winter and he's a bit of a basket case. It's been two different indoors. In the winter he's tense and looky and not much fun to ride.
The minute I get him home to his regular barn he's chill as can be.
I think the biggest difference is at "home" he has 24x7 turnout. The paddocks aren't huge, but he can just get out and wander a bit when he needs to.
It makes me wonder if all those tightly wound dressage horses out there would be so much easier to ride if they lived outside...
