Nanny Needed For My Children

I am a realtor so my schedule can vary but is mostly afternoon to evening. I am looking for somebody who can reliably be available Fridays and Thursdays 10 a.m. until around 7 p.m. The care would be for my infant baby boy. Any caregiver must be comfortable and experienced around large dogs as I have a German shepherd, unless they wish to host the care at their own residence. In that case, I would like to visit the residence in person to ensure it is smoke free and a safe environment.
