The worlds fastest dog breed is a Greyhound. It is the only dog breed that can race in public. They are really expensive and need to stay healthy.
The most vicious dog is a Pit bull. It is also illegal in England.
The worlds smartest dog breed is a Labrador. It can learn really fast.
Yes,it’s all true. German Shepards are also good hunting dogs because they have them in the police force and Rottweilers do the same because I have one and it’s a guard dog.
