Went to pick her up from my friend's last night. Same trailer she gets on every six to eight weeks to come to my house to get her feet done. Last night she just flat refused to get on the trailer. We tried everything we know... butt rope, tapping with lunge whip, feed bribery, even getting onto a different, larger slant load trailer. Nothing worked. It finally got super dark and we had to quit after trying for over an hour. Left my trailer and my friend tried again today in the daylight to get her to load and she still wouldn't load. She's been getting on this same trailer for three years and has never not loaded. And I hated to give up last night and "let her win" but had no choice, I had to work today. But no dice again today for my friend. The mare is pregnant, due sometime the end of this month through the beginning of next month. But I trailered her pregnant last year with no issue. And not to mention I just hauled her 3-4 weeks ago for her farrier day. I don't get it! I'm SO frustrated and I don't know what to do about it.
