you're leaving your beloved pet at home for a holiday, it can turn into a bad experience. Luckily, you don't have to worry about your dogs any more because Rover can cover for you while you are on leave. Rover is the latest service to offer at­home dog boarding. It's a good alternative (替代物) to boarding your dog at a dog boarding kennel (狗舍) or your neighbour's house.

　　The way Rover works is sort of like Airbnb. Dog owners browse the "search" section of the site or app for pet sitters, which can be organized by zip code and available dates. Information of pet sitters is provided, complete with many reviews, specific services and rates. Now Rover has over 25,000 pet sitters in more than 5,000 US cities. And they're all experienced pet sitters.

　　After finding someone that meets your needs, just send messages to the pet sitter to arrange a meeting. Then, like Rover says, all that is left to do is relax! Rover's pet sitters are encouraged to send text and picture information throughout the day, and if there's a medical emergency, the site will send a vet. Besides, don't worry about a pet sitter who falls through, because someone else will soon take his or her place.
