A little help, please?

As many of you know, I'm getting married May 22 up in Mackinac. We already have someone (thanks, Shannon!) lined up to watch our critters (she watched them when we went to Vegas for a few days last year, and jumped at the opportunity to sit for them again -- she loves ferts!) However, the person I was hoping could watch my parent's dogs can't do it now. Can anyone please sit for three little dogs for a few days? My parents would bring them to you and pick them back up. They have an elderly shi tzu (he needs help getting up and down stairs, but otherwise doing well), a chihuahua (he needs eyedrops daily for his glaucoma), and a very happy chihuahua/mini poodle puppy (she's paper trained). They live in the NW Detroit area. So, if anyone is around there, or on their way up to Mackinac, could you please, please help us out and sit three very sweet, loving dogs? We'd appreciate it! Thanks!
