You choose a stallion who is up for stud that you want to breed to. Click on the "Breed" button. It is near where the "Jump Me" button is to jump other horses and the "Message Owner" button.
After you click on breed all of your mares that are 3 or older will show up on a new page. At the top of this page there is some basic information about the stallion and a warning that your mare will not be able to be in jump offs while she is in foal and that her strength will decrease. Her strength will go down to 0% and the stallion will lose 10% of his strength. There is an item to prevent this but if your horse is natural this is what will happen.
Select what mare you want to breed and at the bottom of the page you click on "Breed to Selected Mare." To select your mare you click one of the circles under select heading.

To avoid negative DNA from "Linebreeding" do not breed any horses that have the "Linebred" DNA active or not. Also do not breed horses that are too closely related to each other.

If you have any questions about breeding or about the game in general please feel free to message me at any time.

Thank you
