why is the confirmation price higher than the Host Quote/Dats Sayed

The rate that shows on the sitter's site is the base rate for one adult dog during normal (non-holiday) times. If you have a puppy (under 1 yr old), or a second dog/other animals, or the stay includes includes a major holiday, they may have a different rate which applies to your circumstances. They may also charge a fee for extra services, like pick up/drop off or grooming. To see a breakdown of the fees, all you have to do is view the stay information that is included with your conversation with that sitter. If you have questions about the fees they are charging, ask them directly, because every sitter's rate schedule is different.
