Popular as both a show dog and a family dog, the Bernese Mountain Dog costs approximately $800.

This large breed has a very short life span of 7 to 10 years due to a number of health concerns, including elbow and hip dysplasia and aseptic meningitis, bringing potential healthcare expenses for common issues to around $6,500. The cost to groom this 70-pound to 120-pound dog is around $75.
