The Czechoslovakian Vlak, also known as the Czach Wolf Dog was first bred in the military as an attack dog. Their temperament, trainability, and pack mentality are equivalent to that of a German Shepard. In addition to their jobs in the military, they are also used in search and rescue, tracking, herding, agility, hunting, obedience, and drafting.
These dogs are very smart and obedient. The good news is they will rarely attack a person or animal unless they are commanded to do so.
30. Staffordshire Bull Terrier
This dog may be easily confused with a Pitbull as they share some of the same physical characteristics. Unfortunately, these dogs, like the Pitbull, and many others are bred for fighting purposes.
If you’re in the market to adopt one of these Terriers, it is not recommended that you bring them into a home with small children or other pets as their temperament is very unpredictable. This breed is also known to be very energetic, so they will need to get plenty of exercise.
31. Pharaoh Hound
Despite this dog’s particularly regal sounding name, the Pharaoh Hound is known for its aggressive tendencies. Just look at them you can tell they are slim, fast, and strong.
These dogs also have a high pretty drive, which means it’s not recommended that they be around small children or animals. If you’re looking for a guard dog, this isn’t the breed for you. They enjoy investigating new people and places. It’s important that early on they receive plenty of ongoing socialization to build their confidence.
33. Neapolitan Mastiff
You will be amazed at the size of this dog- it’s incredible. They can reach up to 200lbs. These dogs have been known to kill, and it comes as no surprise considering their size.
They were initially bred to kill which has made them popular guard dogs amongst some dog owners. With that being said, overall, they are fairly calm and incredibly loyal.
34. The Moscow Watchdog
This particular breed of dog is a cross between another well known, and aggressive, breed of dogs. The Moscow Watchdog is a cross between a Saint Bernard, Caucasian Ovcharka, and a Caucasian Shepherd. They truly are massive and beautiful to look at.
These dogs were first bred in the Soviet Union, specifically designed to be military dogs fit for protection. These dogs were bred to serve and protect their owners and because of that, they have a particularly high rate of aggression which can be dangerous to those who are not experienced dog owners.
