I am looking for a sitter who has a greyhound. How do I find one on Rover?

I wish there was a breed search tool function either for a specific breed of the resident dogs or a specific breed the sitter has cared for in the past.

The most time effective way would be to contact rover support@rover.com and use Rover Match to help locate what you need. The user filters would allow you search in an area by those who offer care for large dogs, but not a specific breed such as greyhound. Then you'd have to read through all the profiles to search for one.
