No, there’s not. Inbreeding is totally fine, the game doesn’t care. You get lower percentage when breeding with a friend’s horse, but if you are trying to tier up horses, then using a horse at least two tiers higher than yours gives better % than your own lower tier pair. (So eg. your t1 and friend’s t3 will give you a bigger % for t2 than breeding your own t1 to your t1. But breeding your t1 to a friend’s t2 will give you smaller % for t2 than your own t1 x t1)
