Keep going to the healing springs until your pet is fully healed. The disease will stay there until cured, but your pet won't die or anything. If you have more than one pet, make the healthy pet your active pet as your pet will remain unhappy until cured (and there are some random events which occur if your active pet is unhappy)
Don't pay for the cure
I agree, don't pay for the cure and keep going to the healing springs, but make sure your sick pet is the active one when you're at the healing springs as quite often the faerie will only cure the active pet -- so you need your sick pet to be active at that time.
Then switch out with your healthy pet, and you might want to play more with your sick pet too.
Good luck.
