How many breeds of Molosser dogs are there?

According to the International Cynology Federation (FCI), Molosser dogs are found in group 2 and divide into two additional sections: mastiff or mountain types. However, both of them together make up around 50 breeds. Below, are some of the most well-known Molossers:

1. Bulldog

This breed is originally from the United Kingdom (it’s one of their national symbols) and it was first appeared in 1500.

They get their name from being used to control bulls. Later on, people used them for bullfights. Fortunately, this practice was banned in 1835.

As for its physical appearance, the bulldog (in the picture above) has a sturdy body, large head, wrinkly face, short snout, curly tail (which is sometimes docked), and smooth fur. They can come in beige, white, striped, and reddish colors. Males weigh usually around 22 kilos.

2. Neapolitan Mastiff

This one of the most well-known Molosser because they are enormous. They are the descendants from the dogs that Romans watched fight in circuses. The Latin word “mastiff” means “solid,”, which is one of this breeds main qualities.

The Neapolitan Mastiff is not aggressive, despite its dangerous appearance and powerful size (75 cm tall and up to 90 kilos in weight).

They protective over their family and territory, which makes them great guard dogs for homes that have a good amount of property. However, they can eat a kilogram of food a day!

3. Pug

Even though this breed became famous in the United Kindom, they are originally from China. Also, they are one of the most popular dogs in the world and their small size means they can adapt to life pretty much anywhere.

Just like most Molosser dogs, the Pug suffers from Brachycephalic Airway Obstructive Syndrome because they have a short snout.

It’s also very important to clean their wrinkles on their faces to prevent them from having any fungal issues. If given too much food, pugs can easily become obese.

4. French Mastiff

This is one of the largest Molosser dogs, that belongs to the mastiff family and they were created in France to be a guard dog. It’s one of the oldest breeds in France. They have a firm and determined personality (although affectionate and patient), and they have very strong and powerful.

5. French Bulldog

This final Molosser dog on this list is the lovely little dog you see in the picture below. Even though this breed is originally from France, they became more well-known in England after the Industrial Revolution.

Despite their small stature (30 cm), the French Bulldog complies with the criteria for a Molosser: strong, compact, muscular body, wide head, and flappy lips. They also have cute pointy large ears.

In regard to their personality, they’re sociable, playful, friendly, patient and protective with their children (particularly with females). Although they’re small, they make great guard dogs because they are always alert to strange noises.
