8. Great Dane ($2,000)
Scooby Doo and Marmaduke were both Great Danes and are generally larger dogs. These puppies run a cost of around $2,000 and require a lot of space for when they grow up. They are easy going dogs, but are dubbed the Heartbreak Breed because they get a lot of diseases throughout their lives.
