How much should I charge to pet sit an old Lab for about 8 days. I would go over to it's house 3 times a day to feed it, play with it, give it it's medicine, put in in it's kennel, and make sure it has fresh water. It will stay outside most of the day. Oh, I'm 11 but pretty responsible. I pet sit regularly but this time it's for my old teacher. The house is about a block away so that's not a problem. I have to take it for a walk everyday though. Should I charge them or just take whatever they pay me?
