6. Chow Chow
These dogs are honestly one of the cutest dog breeds when they are just small puppies. But as they get older… well, it appears that it isn’t really in their nature to be that cute. Watch out.
This breed of dogs requires a lot of attention and physical exercise if their owners do not want them to become aggressive in the future. Originally from China, the 50-70lbs Chow Chow can also be referred to as Songshi Quan or “puffy-lion dog” – which makes it sound adorable! This breed has discernment skills against strangers and can be aggressively protective of their owners. Listed as high-risk dogs, they are considered “unacceptable”, and may require insurance due to the 238 fatalities from dog bites from 1979 to 1998.
