Training

Borzoi

MethodPositive reinforcement
Challenges
s:** Repetition bores them. Drill-style obedience will fail. Keep sessions short (5 minutes) and varied [cite: 6].
Tips
  • ** Positive reinforcement only. Harsh methods cause them to shut down or become defensive.

Bullmastiff

MethodPositive reinforcement
Challenges
forced running or jogging on pavement until growth plates close (18–24 months).
Tips
  • ** Positive reinforcement is the only viable path. Harsh corrections often cause this breed to shut down or become defensive.

Borzoi Considerations

challengePredatory Aggression

The Borzoi possesses a predatory sequence (Eye → Stalk → Chase → Grab → Kill). They are hardwired to chase anything that moves quickly. This makes them a significant risk to cats, small dogs, rabbits, and even wildlife. A Borzoi that lives peacefully with an indoor cat may still kill that same cat if they encounter it running outdoors.

challengeSelective Deafness (Independence)

They are not biddable. They do not obey commands for the sake of pleasing you. If they see prey, their recall is virtually non-existent. They require a securely fenced area (minimum 6ft/1.8m) to run; "invisible fences" are useless against their drive.

challengeAloofness

They are often described as "cat-like." They may not greet you at the door with enthusiasm or want to cuddle constantly. They are affectionate on their own terms.

Bullmastiff Considerations

challengeSame-Sex Aggression

This is a genetically rooted trait in many Bullmastiffs. While they may coexist peacefully with dogs of the opposite sex, placing two males or two females together often results in severe conflict once they reach social maturity (18–24 months). This aggression is rarely "cured" through training; it is managed.

challengeStubborn Independence

Bred to track and hold poachers silently without human direction, the Bullmastiff is an independent problem solver. They do not have the "will to please" of a Golden Retriever. If a command does not make sense to them, they will simply ignore it. This is often misinterpreted as stupidity; it is actually a refusal to perform rote tasks without high-value motivation.

challengeThe "Velcro" Guardian

While independent in thought, they are physically clingy. They will lean their 120-pound bodies against you, sit on your feet, and follow you from room to room. This constant physical presence can be overwhelming for owners who value personal space.
