4 1/2 month puppy needing a walk during the middle of the day. Needs to be walked so he can evacuate and get some exercise while I'm at the office.

I need someone to check in on my guinea pigs, feed them fresh hay and vegetables, and change the water in their water bottles daily. I would like that person to pet and talk to my guinea pigs, too. I would need this person for occasional getaways of a few days to a week.
