Russian Black Terrier

At first glance, the Russian Black Terrier looks like a show dog with its thick and fluffy coat and cute face. But this breed is also known for being very smart and confident, the reason why it has been trained as a guard dog for many decades.

The Russian Black Terrier is a great breed to have around the house because it knows how to protect people and properties. These dogs grow to be very muscular, weighing up to 140 pounds, so they’re great for keeping unwanted strangers out of the house.
