52. Beauceron
This dog is not for the faint of heart. Beaucerons are robust and muscular dogs with a strong presence. Reaching as high as 27 inches at the shoulder, these dogs can do quite a bit of harm. The American Kennel Club has described these dogs as “well-chiseled”, with dark brown eyes that “project an expression breed fanciers describe as frank and confident.”
It is important to stay dominant with these dogs as they can very easily dominate a weaker owner. It is good to note, however, that once these dogs are disciplined, they are excellent with the smaller and defenseless.
50. Estrela Mountain Dog
This is one old dog breed and is believed to be the oldest one of the LDG breed. With high energy and fierce tendency to protect, this dog is perfect for large areas and landscapes such as farmlands or just large properties in general.
This dog is wildly protective of its owner and extremely docile with the ones it loves, but strangers, beware, this dog will stop at nothing to protect its family and its land.
51. Hovawart
This is no easy breed and not is exactly ideal for the new dog owners. These dogs lean towards the stubborn side and need quite a lot of attention. For owners who do spend their efforts on teaching this kind of dog the appropriate behavior, the reward is having an incredibly loyal pet.
It's important to remember that these dogs love a job. Without it, they can get aggressive. They are amazingly creative worker dogs with high levels of energy. Hovawarts are wonderful for search and rescue organizations, therapeutic activities, obedience trials, agility trials, flyball and also make great service dogs.
53. The Finnish Spitz
This little fox-like bushy dog is pretty fierce for its size. Sharp and alert ears make this dog highly observant. Finkies or Fins as they are nicknamed can be an excellent combination of a loving friend and a watchful guard.
What makes these dogs extra fierce is their bark. This is no quiet breed and in Finland, owners actually hold barking contests. The winner gets crowned "King Barker". So if you're looking for more than one way to scare off unwanted visitors, a Fin might do the trick.
54. Griffon Nivernais
Originally bred to hunt wolves and wild boars in the fourteenth century, these dogs have a ferocious past. Now, a little calmer, a Griffon Nivernais still carries a predatory instinct. This French breed is a little larger than most French hounds and stands between 21- 23 inches.
It may not look like the most agile and speedy type of dog, as this dog bred more for endurance than speed.
