Caucasian Ovcharka
The Caucasian Ovcharka was traditionally bred to protect livestock, and is also known as the Caucasian Shepherd. The breed has a reputation for being assertive, strong-willed and courageous, so might make a loyal family companion. However they need to be properly socialized and trained, as they still have ferocious and unmanageable tendencies and a powerful urge to defend.
Borzoi
Borzoi dogs look a lot like large, tender, graceful poodles. These friendly white giants can are properly trained and socialized, and can shine as great family companions. However they can still be very stubborn at times, so you might have to be patient. They are also known for rough play because they probably don’t realize their own strength, so you might have to watch out when they’re around smaller kiddies.
