Training
Bolognese
- ** Positive reinforcement ONLY. They are sensitive souls; harsh corrections will cause them to shut down or become fearful [cite: 8, 14].
Rottweiler
- Prioritize neutral socialization between weeks 8 and 16.
- Instill rapid impulse control and an immediate release ('out') command during play.
- Desensitize to mouth, ear, and paw handling during early puppyhood.
Bolognese Considerations
This is not a breed that tolerates isolation. The Bolognese was bred exclusively for companionship for centuries. They do not have a "working" mode that allows them to be independent. If left alone for more than 3-4 hours regularly, they are highly prone to severe separation anxiety, which manifests as destructive chewing, house soiling, and distress vocalization.
Unlike the gregarious Bichon Frise, the Bolognese tends to be more serious, reserved, and shy with strangers. Without early, positive socialization, this reserve can turn into fearfulness. Furthermore, owners often baby them due to their size, leading to "Small Dog Syndrome" where the dog becomes neurotic, demanding, or snappy.
Like many toy breeds, the Bolognese can be difficult to house train. Their small bladders and a tendency to be sneaky about accidents require patience and consistency. They may regress during adolescence or if the weather is poor.
Rottweiler Considerations
Not novice friendly; unsuitable for inconsistent, permissive owners or individuals intimidated by physical strength.
Categorized as restricted/dangerous dog (Listenhund) in parts of Europe and US municipalities, frequently banned by rental landlords and homeowner insurance.
Handlers must manage 45-55 kg of physical pulling power and potential same-sex dog aggression.
