For example, if the house sitting rate is $30 - if you have 2 dogs, is that still $30/night or is it $60/night?
The rate shown in the search results is for one pet. The site will charge that rate per dog, unless the sitter has an Additional Dog Rate for their house sitting service. If they do have an additional dog rate, then the rate that shows on their profile will be applied to the first dog and then the second dog will be charged the additional dog rate. You can find out if a sitter has a different rate for additional dogs by clicking on the Additional Rates & Services button on their profile under their rates.
