Anybody else have a horse that can not be tied while grooming?

I was just wondering if anyone else on here has or has had a horse that could not be tied for grooming? The reason I ask is, my horse Lady the one in my avatar gets so relaxed while grooming that she will fall asleep and fall over. I don't tie(for grooming) her because she has fallen over on several occasions, and I don't want her getting hurt. I've never had a horse that gets that relaxed from grooming, and I was wondering if there were others like her or is she just weird?

Falling over? That concerns me a little bit. I would have her looked at for maybe some kind of mental tweak.

Wow, I've dealt with horses that couldn't be tied because they would pull back but never one that relaxes to the point of falling over. I agree, you might want to get that checked out.

I've had her evaluated by the vet, nothing wrong. She just gets so relaxed, and into such a deep sleep that she falls down. I've even showed it to my vet, and he couldn't explain it.

During her grooming I will make her yield either for front or rear quarters to wake her up periodically. If I do that, she won't go to sleep and won't fall, but I don't tie her in case I forget to do it, better safe than sorry. She never does it when she isn't being groomed, she just really enjoys being groomed.

My friends horse Lady does that also, you just have to lightly hit her and call her name she wakes right back up.

Wowzers. That's wierd! I've had horses fall asleep, but not to the point of falling over!

That's too funny, my horse that does it is also named Lady!

Does your horse live alone?

Nope, she shares a pasture with my other horse Fancy.
