I am a Nanny and had the exact opposite problem with my boss. I begged and pleaded with my boss to get the dog. I would work with her all day and even took her to OB. At night, my boss would "undo all the good I had done". (Didn't watch her, take her out on time, etc.) It is very difficult to be successful if you and your Nanny are not on the same page. If Nanny is home with the dog all day, and does not feel the dog is her responsibility, the dog should be crated, or put a run, or whatever, but should not have run of the house. Just as you would expect Nanny to follow your wishes when it comes to raising and disciplining your children, the same is true for your dog. I would set up a schedule and go over it with Nanny. Be clear in your expectations. For instance you might say "i'll feed the dog in the AM and take him for a walk. He will go in his crate before I leave for work. At noon, please bring him out and put him on his run. At 3, please bring him back in and return him to his crate until I get home", or whatever. It took 9 months to Potty train Dakota b/c we were confusing the crap out of her with our different approaches. I agree with everyone else also, but know exactly where you're coming from with the whole Nanny thing. BTW, I'm curious how much Nanny knows about dogs, and their relationships with children. For instance, I continually work with Dakota, who's now 2 1/2, to make sure she never has any food aggression. Dogs "see" children differently than adults, so while they may be fine with you near their food, they may not want the kids there. How does Nanny feel about the dog?
