Training
Irish Water Spaniel
- ** Positive reinforcement is mandatory. They are sensitive dogs that shut down under harsh correction.
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.
Irish Water Spaniel Considerations
Unlike the "everyone is a friend" Golden Retriever, the IWS is naturally aloof and watchful. Without extensive early socialization, this reserve can escalate into fear-based aggression or sharp territoriality. They are known to be discerning and will not automatically welcome guests into your home.
This is a "Velcro" breed in the truest sense. They bond intensely with their family and often panic when left alone. Destructive behaviors (chewing through drywall, destroying crates) and excessive vocalization are common failure modes for owners who work long hours away from home.
As a bird dog with a "soft mouth" for retrieval, they still possess a significant prey drive. They are generally unsafe around small non-canine pets (cats, rabbits, hamsters) unless raised with them under strict supervision, and even then, the instinct to chase is powerful.
While intelligent, they are not blindly obedient. They often ask "What's in it for me?" and can be manipulative or "creative" in their interpretation of commands. They require a handler who is firm, fair, and consistent, but never harsh.
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.
