I have two beautiful Bernese Mountain Dogs, boy & girl. I am home full-time, but need occasional coverage for when we go out of town. My dogs are very friendly, but the boy is young (14 months) and can be a handful when greeting. Once he settles he's very good. I mostly would need you to come in the middle of the day for a couple hours - your first time or two could be here in the backyard, and with leash walk on our (short) street so you can get comfortable with them Later, they're great in the car and love walking in parks, etc.
