Question about Adopting dog?

Umm I don't know for sure about the first two questions,but I do know the third one. You need to ask the owner what kind of food they need and get the right kind,also don't feed him/her to much,otherwise they will get fat.And you wouldn't want that! Also you probally want a couple of toys for him/her to play with... You will want the right shampoo and brush. And that I think is pretty much it. Your Welcome! :) -Emily
