Well I have to bring this subject up again.Sonny the old horse I havethat I thought was a gelding is not, he is a stallion.I had a vet assistant out here today to take a look and she said he is a stallion, she thinks because he was so under weight that we never saw it, said she has came across this before, so now that a I have mare he has been following her around everywhere, I noticed today after she went poop he went up to it and smelled it,pawed the ground and pee'd a little on it, then walked slowly away.I don't know nothing about breeding or when the mare goes into heat, Anybody have any suggestions whats going on?
