How often do your wolves get sick?

I've had such a spikt today from hunting... It made me think the bugfix/change of settings broke XD But the days before that were very calm

probably once a week or every 3-5 days, I run a hospital run on donations so sometimes ill use the meds from my hospital for my own pack and ive never had more than 2 wolves sick in one day. Usually they get it by my lead rolling in poop, or after a hunt.
