My mare almost always lathers up in sweat, regardless of what we do, even if it's just a long walk. It was about 70 degrees today, and that's plenty warm for her to lather up. Today, she hardly sweat at all. She sweat under her saddle, but nothing like she usually does. While we were riding, she peed twice, maybe 30 minutes apart, and I didn't think much of it.
When we got back, I noticed that she still wasn't sweating. I tied her in the barn, and went to get my groom box. While I was gone, she peed on the concrete aisle of our barn. I moved her to a new spot in the barn, and threw a bucket of water on the puddle. Less than two minutes later, she peed again in the barn! That's when I thought something was really wrong.
She wasn't in any pain, her ears were up, her eyes were bright and clear, her nose was clear, and she was breathing normally, had a normal heart rate. There was no blood in her urine, nor was it cloudy or anything like that. She shouldn't be due to be in heat, either.
I put her in her stall and gave her dinner, which she ate well, and I gave her a flake of hay. She peed four more times in the next 10 minutes. She didn't drink any water, though. I led her to the trough and she refused to drink. I put her back in her stall, and she tried to pee two more times, but there was nothing left in her bladder I guess.
I called the vet and he said to leave her in her stall tonight (they usually get 24 hr turnout with 24 hr access to their stalls) and watch her, and if she's not doing better by tomorrow, we'll schedule an appointment. I turned off her auto-waterer and replaced it with a bucket so I could monitor how much she drinks.
Do you guys have any idea what would cause this? Could it be a bladder infection?
