Horses can have twins too, but it would be dangerous to them

Horses can have twins too, but since there is limited room in the uterus, the smaller embryo is usually ‘pinched off’ by a veterinarian professional.

Horses having twins is already quite rare, but it can lead to the abortion of the mare. Even if the twins do survive, they are usually weak or non-viable. Usually the best decision is to ‘pinch off’ the weaker embryo, thus leaving room for the already stronger one. However, some foals aren’t checked or just left alone after the pregnancy check, so there are twins in the horses’ world too.
