Bathroom requirements

by Emma K
(Manhattan )

I may be house sitting for a family with an adult jack Russell terrier. I would be living at the house during the 3 weeks I'm needed (and will be available for morning and evening walks, however I work during the days. I wanted to know approximately how often do (fully house-broken) terriers need to be let out during the day to pee? Just so I know whether to request to leave early from work or not.. I'd appreciate any advice!

Thanks!
