Bullmastiff Considerations
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.
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.
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.
Curly Coated Retriever Considerations
If you want a dog that loves every stranger at the brewery, do not get a Curly. They are naturally wary of strangers and will patrol their territory. While not aggressive without cause, they are serious watchdogs who reserve their affection for their inner circle.
This breed does not obey commands simply because you asked. They assess the value of the request. They are known to open doors, gates, and cabinets. Their intelligence is manipulative; they will find the loophole in your rules.
A Curly may remain a "puppy" mentally for 3+ years. Owners expecting a settled adult dog by age 2 will be frustrated by the prolonged adolescence and testing of boundaries.
