Irish Water Spaniel Considerations

challengeStranger Wariness & Protective Instincts

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.

challengeSeparation Anxiety

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.

challengeHigh Prey Drive

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.

dealbreaker"Spaniel Stubbornness"

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.
