Suggestion one: I think it would be cool to be able to create bonded pairs that can only breed with each other. This would help prevent accidentally breeding the wrong wolves, and would make it slightly easier to breed specific pairs
Suggestion two: When you select a wolf to breed related wolves should be removed from the list of potential mates. Right now they are greyed out and unclickable, but they still show up in the list. This creates a lot of unnecessary noise and can make it harder to find the wolf you want to breed. My current main breeding wolf is related to more than half the wolves in my den and picking her mate out of her sea of children sucks
