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.
Lagotto Romagnolo Considerations
The Lagotto was historically a watchdog on the barges of the Romagna marshlands. This instinct remains intact. They are . They will bark at delivery trucks, neighbors, and leaves blowing across the driveway. Unlike a Golden Retriever who might welcome a burglar, a Lagotto will announce them loudly. This makes them challenging for thin-walled apartments.
This is not a "love everyone" breed like a Labrador. Lagottos are naturally reserved and can be suspicious of strangers. Without extensive, positive socialization during the critical puppy window (8-16 weeks), this reserve can curdle into fear-based reactivity. They often require a proper introduction protocol before accepting new guests into the home.
This is the only breed in the world specialized for truffle hunting. The instinct to dig is . If you do not provide a designated digging spot (like a sandbox) or engage them in nosework, they will likely "landscape" your garden or dig at your carpets.
