One of the big problems with having a dog is that when you travel, you need a place to keep it that will be responsible but not too expensive. Dog Vacay is working to solve this problem, by connecting dog owners with dog watchers, and lowering the average cost of the stay. This is the same model that Airbnb uses, in that Dog Vacay utilizes overflow space that could otherwise be making people money.
