I will be going out of town for 11 days and need a dog sitter for 3 of my dogs. I can't figure out the cost on this. I would need someone to let my dogs out 3-4 times a day and prefer that they stay at my home, but when I click on house sitting it gives details that the dog is let out every "2-3" hours, but does this only mean at night? Will I have to pay the drop in rate for each time and for each dog, or just pay for the house sitting services?
