Saint Bernard
The Saint Bernard breed is quite infamous thanks to the movie Beethoven. These dogs are very adorable and can be trained, albeit harder due to their very playful nature. They can be trained to behave well around small children. While they look lovable, the main problem with these dogs is their enormous built and size. They have the tendency to unwillingly hurt small children by knocking them over. The thing is, the playful nature and the size of a Saint Bernard make them difficult dogs for families with very small kids.
