Andrew was asked by a neighbor to dog-sit for her on occasion when she goes out of town. She said she is usually only gone for a night or two at a time, usually every other week. They have a great set-up for their 2 dogs at her house, so his work will be fairly easy. The dogs have a pen in her garage and there is a door that leads from the garage directly into a large outdoor pen for them. Andrew has to go over in the mornings to open the door to let the dogs out, feed them and give them fresh water. Of course he will spend some time playing with them and giving them some love, too! That is all she is expecting of him until evening when he is to go back to let them back into the garage and feed them again. She asked me to come up with a "pay" for him that I think is fair - the thing is, I have never done dog-sitting nor had someone do it for me, so I have NO IDEA what people pay or charge for this. What do you guys think - how much should a 13 year old get paid for this?
