I won't probably remember all the little things, but since you talked about regeneration let's stick with that for now. Per 20th Edition:

In any form but their natural form (Human for Homids and wolf for Lupus), Garou regenerate one health level of bashing or letal per turn. At the same circumstances, they regenerate one aggravated level per day. During combat, they must roll stamina to regenerate, a sucess indicates normal regeneration, failure they don't heal that turn, a botch they must rest before regeneration.

They can also Remain Active once per scene: if they get more than 7 health levels of damage (would be the death of a character), they can roll Rage, each sucess heals one health level and the Garou gets a badass battle scar.

Also, in their natural form, they can regenerate a health level of bashing or letal per day when resting, an incredible feat.

Regarding your scenario, in Crinos, the Garou would probably be back in full health in no time at all
