Friend's DC (18) is looking after our dog while we all go out. DDog can cope with about 3 hours max on his own, but we'll probably be gone for about 5 hours. He'll be fed and walked before we go, but friend's DC will be in the house and give him a quick walk to do his business before his bedtime. Friend's DC will be provided with the usual snacks, wifi password, access to Netflix etc etc. How much would you pay them?
