Just as you have asked your breeder many questions, be prepared to have many asked of you! You are attempting to "adopt" one of their "children", and you will find that they may ask such things as:
Have you ever owned a dog, more specifically, a Shorthair, Pointer, etc. before? If so, what happened?
Do you have children? How old are they?
Do you have the room to keep an active dog? Would you consider fencing your yard, if it is not already?
Will the dog be kept in the house? In an outdoor kennel? On a chain?
If you plan to show the dog, are you aware of the expense for entries, travel, supplies, etc.?
Are you aware of the veterinary needs of a dog, such as heartworm medication and routine checkups and shots?
