Dr. Lowder,

My miniature mare is 304 days pregnant that I know of. She may be further along as she had been in with the stallion. She is a young maiden mare. Yesterday she had some bloody show and has been pawing, standing up against the wall, she also will stand as though she has to urinate and only a few drops come out. She paces her stall and holds her tail up alot and flickers her tail. Today her temp has dropped to 98 degrees from 99.3, my question is could she be ready to foal?

Dear Terry,

The normal gestation length for a miniature horse is 330-342 days. Signs to watch for that commonly precede parturition are development of the mammary gland (udder) 3-6 weeks prior to foaling and then distention of the udder with colostrums 2-3 days prior to foaling. Waxing of the teats (where colostrums drips from the teats and forms a waxy coating at the hole in each teat) occur in most mares 6-48 hours before foaling.

Signs of foaling being imminent include sweating, the mare being restless and sometimes rolling, frequent defecation, and straining. If your horse exhibits these signs for more than 2 days and does not progress to the next stage of labor (when she will be laying down trying to deliver the foal), then there may be a problem and you should contact your veterinarian.

Good luck!

Thank you,
Dr. Lowder
