What does your breeding routine look like and what do you do?

Each of my animals has a designated pair, and up on my layouts (thanks to the amazing blitz), I have dates when all of my backup breedings are to be done and when all of my final breedings are to be done.

And some pairs can't be bred together, so I use different emojis to mark down which lines/pairs cannot be mixed together. 

Each animal has one designated mate, wait until they turn 15 (for dogs) or 20 (for horses), breed them. -shrug-

Everyone has a specific mate. But I breed multiple times so I can try to sell backups to earn HPD from all my work in training every week. Then keep the very last one for myself to keep the line going.
