how much a month do you think it would be? I dont mind to pay a dog walker - I am basically willing to do anything so that I can have a happy companion.
We adopted Cowboy when he was 18 months...and there couldn't be a closer bond than Cowboy and I. As I write, he right next to me with a paw across my foot. We are always right next to each other. I think it depends on the dog, but galaxe who just got Grizzley/Izzy (a 3 1/2 year old Newf) will say that he's already bonded as well.
For the best info., try contacting the Newf Club nearest you and ask them about the Newfs in rescue in your location. Here in So. Calif., we have many Newfs who are in foster homes.
Good luck and keep us posted!
