At any rate, my leased mare showed me some new behavior this week. Two days in a row, I saddled up, walked into the arena to mount, and after adjusting the girth for mounting, she peed in the arena. She is typically shy about this, preferring her stall. I had never seen her go anywhere else prior to this week.
I have a statistics background, so seeing this two days in a row after never seeing this before gets the wheels turning- is it likely that this would happen 2 days in a row by chance? I'm wondering if this is something to worry about or simply coincidence?
Here's what I think is the relevant background about Isabel:
-I typically ride her 4 times a week, generally in the morning
-She has recently (last 3-4 weeks) started being used in lessons with two teenage riders. She seems to have mellowed considerably since she's getting more "kid time," but has also recently started holding her breath for girth-tightening, which is a habit I'd never seen in her prior to this (and would like to get away from, which could be difficult with different people riding her now, but I suppose that's a different thread)
-Her saddle has recently been adjusted by a master saddle fitter
-The tack we're using hasn't changed otherwise
-She has a relatively weak back that we're working on, and it's been a few months since she's seen the chiro
-It has been hot where we are this week (high 80s F to low 90s F) but she spends most of the day in a paddock with a covered run-in and nights in the barn. This is her typical routine and has not changed.
