Okay, story time. We got this mare on Saturday for my boyfriend so he could accompany me on trails. She is a chunky horse, and I thought nothing of it. This morning I go out and I look at her udders (my gelding has a swollen sheath because of a bee sting so since I was looking in the nether regions I thought I’d check her out too) and I see that she is lactating. It is very white, not yellowish at all. She is on bermuda hay and they are both out in pasture. I give her and the gelding some soaked alfalfa cubes in the AM. Previous owner said she was out on pasture with other mares and a 2 yo mule colt. She had her for two years (or so) and said she doesn’t think there was a chance a stud could’ve been in with her. Hormones just out of wack? A vet is already coming out Tuesday to check them both out so I’ll have him feel around to be sure but I just wanted opinions. I’m new to the whole horse thing so anything helps, thanks!
