3.Rottweiler (up to $7,000)
Rottweilers were originally bred as pulling dogs. They are fearless, territorial and protective of their owners. It is important to start socialization at an early age, even though Rottweilers are generally good-natured and placid. They are great family pets, as celebrity Rottweiler owners like Will and Jada Pinkett Smith can confirm.
While Rottweilers are fairly common, champion lines found at dog shows can cost up to $7,000. They can also get expensive when it comes to trips to the vet. Unfortunately, they are prone to cancer, allergies, gastric torsion and hypothyroidism.
