Would it put you off a childminder if they had a dog? My exact situation is that I have one dog, a king charles cavalier spaniel. He would be kept in the kitchen behind a stair gate when the mindees are in the front room (where they spend most of the time). When we are in the kitchen I wouldn't usually (with my own kids) think to shut him out as he is very chilled and just lies in his bed, comes over for an occasional stroke but I obviously could if this is what the parents want.
I have 2 kids myself and the dog is no trouble, he's a total softie but appreciate some parents might be put off? I'm hoping not all?
