Pregnant Mares Pee More

My mare is pregnant. It seems that she urinates more frequently than when she was not pregnant. Every morning the corner of her stall has way more pee in it than it did before she was pregnant. Since pregnant humans urinate more frequently I figured it was entirely possible this is a mammal thing and not a human thing. In an effort to determine the accuracy of this postulation I went online and searched Do pregnant mares pee more?

All I found was post after post about Premarin™ and how pregnant mares are abused to steal the hormone from their urine so humans can look younger for a few more years. Do pregnant mares urinate more frequently? Same result. Pregnant horses frequent urination? Same result. No matter what search phrase I tried, if it included pregnant and horse or mare, I got the same result, posts all about humans abusing horses to steal their hormones. Gads, humans make me squirm.

Finally, I gave up and tried Do pregnant mammals urinate more frequently? That brought up post after post about how pregnant humans urinate more frequently. Nothing about other mammals. One post about how much elephants pee in general, but not while pregnant.  Guess I’m going to have to call the vet and ask (I tried while writing this but since it is Saturday, they are closed). My suspicion based on the reason humans pee more frequently while pregnant is that horses do indeed pee more frequently.

While cleaning stalls this morning, I was thinking about my inability to find the answer to this question on the internets and decided I should write about it so that if someone else out there searches for the answer to this question, maybe they’ll find my blog and I can answer it for them. After I call the vet and ask, I’ll post the answer so it will be here for all to read about instead of finding posts about humans torturing pregnant horses.
