Would it be possible to add a config element to change what animals are able to be hauled using the animal cart? I'm playing using the Doggy Talents Next mod, but once a dog has been converted to the modded version using a training treat, the animal cart can no longer pick it up. I'm not sure how difficult that would be to implement, but if it's possible, the option would be lovely!

Every Land Mob can sit in the Animal Cart if the Mob is not too large. This seems to be because Doggy Talents doesn't allow dogs to mount other entities.
