So, I've had my mare six months And she is very overweight. I did a pregnancy test on her. It was negative. Good went in my merry way. Have now been told that she looks in foal and pregnancy tests aren't accurate help pls?! Pics of the mare:
Has she still got a "waist"? They usually thicken around the area just in front of the hips about 1/2 way through the pregnancy. If you are worried, it is worth asking your vet to check
Another that thinks judging by these and the previous pics you posted that she is obese rather than pregnant but would get a vet out if I were at all concerned she may be in foal.
