5. Old English Sheepdog
Old English Sheepdogs are intelligent and loyal herding dogs that are great for families with children. They are most well-known for their role in the film “The Shaggy Dog,” however. These fluffy companions require regular grooming and can be purchased from breeders for close to $1,250 each. Because they are prone to a number of health issues, including deafness, cataracts, gastric torsion, otitis externa, and others, the average annual cost of this breed’s veterinary care is over $7,000, making them one of the most expensive dog breeds.
