The closest thing so far I'd say would be
LittleMissSam's mod, But unfortunately that's only for npc pets. It sounds like you have either that awful puke bug or it's the preventative shot glitch (if your pet has ever gotten that shot, sometimes it causes more sickness than it prevents).
I've had many pets get sick in my game but 90% of them are the npc pets though (blue dirty dogs has been a norm since I got the pack :lol: ). So this mod helps a bit with that. If I see one that helps the active family's pets, I"ll post it here.
