I was wondering when do mares start relaxing their butt muscles. My Mare is 293 day today and when I was groom her today I noticed that her tail was more relaxed then normal. Usually when I grab her tail she tightens up but today there was almost no tension in her tail. I push on the muscles next to her tail they are soft but not like jello like I have heard people mention. I was wonder if this is normal or if I should call my vet. He is coming out next week to give her spring shots.
Should I see if he can come out sooner?
Not the best picture but I grab these quickly today with my phone.
