Depending on where you adopt, fees can range up to $400. Purchasing a Great Dane from a breeder can cost between $600 and $3,000, depending on the breeder and the dog itself. The higher price tag usually comes with a show-quality dog, which you might not need if you're just in the market for a pet.
On average, a puppy can cost anywhere from $500 to $750, but dogs that have an AKC champion bloodline will be in the $1,000 to $2,500 price range. For example, on the official AKC Marketplace, one breeder had one up for adoption for $2,000 to $2,500.
