I went to feed my horse and I noticed she walked kind of funny when coming to eat her grain. She didn’t walk very far, like a couple of feet, so I thought maybe she was just loopy and tried to scramble over to her food. I was a little concerned but waited for her to finish her grain until I pulled her out to check. I filled up her hay bag and hung it up. As she was walking towards it (it’s all the way by the gate), she seemed to walk perfectly normal with big long strides. So I was assured that nothing was wrong, but then I saw her walking really carefully. I thought maybe it was because it was kind of icy, but as she walked into her shelter she looked like she struggled a bit. I caught her, brought her out, walked her around the arena, and she seemed fine. No tripping, no head bobbing, didn’t resist leading. Then I let her loose in the arena and she looked a little off. I stopped her, tried to pick up her foot and see if there was anything in it, and she just wouldn’t pick it up. She resisted a lot. She’d pick it up lightly, but not bend her knee. I thought she was being bratty (she normally is sometimes) so I started tapping her foot with the hoof pick or softly squeezing her chestnut, but she was persistent. Usually the tapping is all I need. Then I heard her try to bite me. While she didn’t make contact, I heard her open her mouth and snap at me. I know she only does stuff like that when she’s hurting, so then I started getting really worried. When she finally picked up her foot, I cleaned it and took a look as quickly as possible. Nothing. Put her foot down and started to feel around her leg for any heat, lumps, pain responses. As I ran my hand around her legs, she proceeded to snap at me 3 more times. I’m surprised she didn’t actually bite me. I was confused at first because I didn’t squeeze her leg or anything, I just felt along her leg. It must’ve meant she was really sensitive or hurting somewhere. I didn’t feel any abnormal heat or abnormal lumps. Also felt for any heat in her hooves, nothing. I could feel her bones just fine and no obvious signs of injury. I’m really puzzled because she was walking perfectly fine at first, then looked a little lame, then went super lame after checking her out. I’ve heard of horses faking lameness but I don’t think my horse ever would. Plus the biting? I don’t know. It could be an abcess as she’s had them before a few times in the past years and usually go away after a while. Farrier says her feet are great and healthy. But the increased sensitivity and her snapping seemed really odd. The only other time she’s done that is when she had ulcers, but she never had a problem with having her legs touched. Usually when she’s got an abcess, she doesn’t have an attitude like that when being handled. She’s also done something funky with her hind leg in the pasture causing it to flare up for a few days before. I was thinking maybe she might have done that again but with the front leg? She’s not with other horses so she couldn’t have been kicked or something. I wish I had Bute on hand, I’ll probably get some tomorrow to see if it helps her. I’m not sure if I’m just worrying too much, but I want to know if anyone else’s horse has been like this before. Money is super tight as we’ve been hit with brain surgery bills and my car’s axel just broke. This is really unfortunate. Thanks for any tips or advice.
