Spring time. It happens. Just keep an eye on it. It should resolve. If she gets warm and/or hard call the vet.

 

Good to hear she dont have cushings, the reason I asked is that sometimes a mare that has cushings might produce the hormones to cause them to do this..
I have had a few mares over the years to produce the Witches Milk (no cushings) just something to do with hormones as they age. Its more of a clear kinda milky looking fluid.

So very odd, thank you all for confirming nothing to worry about for now! I'll keep an eye on it for any changes. I usually clean the build-up between her teats before every ride, and would've definitely noticed this before!

Next spring during our annual visit, I'll have the vet test for Cushing's just to be on the safe side.

 

My old mare has some fluid about all the time. Last year I was rubbing her belly + further back because it makes her happy and came away with a wet hand. That was a first that it leaked out on its own but it never turned into an issue. Another mare years ago got mastitis and you will definitely know the difference.

 

Thats what we call Witches Milk, nothing to worry about..
Question- Does she have cushings?

 

She has not been tested for Cushing's, and has not shown any symptoms to suggest testing for Cushing's.

 

I had a paint mare that would leak . She would get really fat just above her teats on her belly. When she came into heat in the spring she leaked. It was all hormones.
