I still have yet to find any breeders with puppies (btwn 8-12weeks) i want it as an companion, not show or anything like that. Just to have as part of my family!!!!!
It is not likely that you will find a reputable breeder with a puppy ready to go. Most have waiting lists and pups are most often sold before they are even born.
A good family companion is a healthy dog, as has been stated, purchase price is generally between $1500-$2000.00. This will get you a puppy from health tested parents (tested for vWD, DCM, Thyroid, Hips, etc.) and will include tail, ears, vaccinations up to date, worming... and other important things such as socialization, breeder support, etc.
Dobermans are riddled with health issues and it is wise to research thoroughly, build a relationship with a breeder and get on their waiting list.
Good luck with you search and welcome to DT!
