I make a lot of custom modpacks when I get bored, and I've noticed that when I have the Domestication Innovation (which is basically a required mod for me at this point) with my favorite mob variants from nyuppo, I realised that because of the changes made to breeding wolves, there is no way to naturally get three of the dog variants. This isn't a major issue, but it might raise some questions with compatability with other packs, thought this might help :)

The page for the mob variants:

If you need more details, the French Bulldog/Pug, Golden Retriever/Shiba Inu, and the German Shepherd are all impossible to get. When you breed two of the other dog types, like a husky and a brown dog, you're supposed to get a German Shepherd. This doesn't happen, and I'm assuming that's because of the changes to breeding this pack makes. Either way, thank you for the mod, I love it even if it doesn't work with this haha
