If a child plays roughly with a young dog, the dog sometimes will respond by playing rough with the child. For these reasons, small children should always be supervised when around a Borzoi. Yes, if they are raised around these animals. Borzoi are puppies for a long time so the destructive tendencies of puppyhood are there for a long time in a very large puppy. Training and temperament of the individual Borzoi and its bloodline are factors.
Boredom can be the cause for some destructive behavior.
In fact, most Borzoi grow to love their crate and regard it as their special home, even with the door left open. Crates are humane and take advantage of the dog's natural den instincts.
