German Shepherd German Shepherds were bred as herding dogs and began gaining popularity in the United States in the 1900s. These pups can grow from twenty-two to twenty-six inches tall at the shoulder and weigh up to ninety pounds. They are very courageous, loyal, and confident but need regular training and socialization. German Shepherds are very connected to their families and want to please their owners. Their athletic ability and willingness to protect their loved ones can be dangerous if they’re allowed to run wild. German Shepherds also don’t make friends quickly with new people; so, be cautious when meeting one for the first time. 6. Caucasian Shepherd As you probably figured out by its name, this breed started out protecting livestock and property from predators around the Kavkaz mountain range in Eastern Europe. They stand at about thirty inches tall and weigh up to one hundred seventy pounds. Caucasian Shepherds are companions and watchdogs in the present-day. These pups need a lot of training because they are highly intelligent and independent. They are also extremely protective of their owners and their territory, which isn’t shocking since they were bred to be that way. However, it’s probably not the best idea to let people come into your house if you own a Caucasian Shepherd. 5. Wolfdog Wolfdogs are the results of domesticated pooches breeding with wolves. Their behavior is often unpredictable because they have a wide variety of genetic characteristics. One example is the Czechoslovakian Wolfdog, which is very independent and dominant and was initially bred for border patrol in Czechoslovakia. They’re wary of all strangers and can be very dangerous if they’re not strictly trained. They grow up to twenty-five and a half inches tall and weigh up to fifty-seven pounds. They look very similar to regular wolves, and it’s best not to approach one that isn’t your own.
