vetstreet.com: 15 Worst Dog Breeds for New Pet Owners

11 of 16

No. 5: Rottweiler

Although he can be a gentle giant, the wrong Rottweiler with the wrong owner can truly be a scary dog. A Rottweiler wants someone to be the boss, and if you’re not taking the job, he will. He’s powerful and protective, and known for being extremely loyal when it comes to his people and his property. Considering he can weigh as much as 135 pounds (and most of it muscle), he can generally back up his threatening growl.
