The Portuguese Water Dog (PWD) is a highly energetic and intelligent breed known for its curly, hypoallergenic coat and exceptional swimming abilities. Originally bred to work alongside Portuguese fishermen—herding fish into nets, retrieving lost tackle, and swimming messages between boats—they are devoted 'Velcro dogs' who bond intensely with their families.

Training

Irish Wolfhound

MethodPositive reinforcement
Challenges
Requires consistent, patient training
Tips
  • ** They are sensitive and shut down with harsh correction. Positive reinforcement is the only viable method.

Portuguese Water Dog

MethodPositive reinforcement - sensitive to tone and can shut down with harsh correction
Repetitions to Learn5-15
Challenges
High intelligence but manipulative - will test boundariesIndependent streak - need to know WHY they're doing somethingAdolescent regression at 1-3 years - may challenge authority
Tips
  • Use high-value treats and toys - 'Because it pays well' works better than 'Because I said so'
  • Keep sessions varied and engaging - they get bored with repetition
  • Channel mouthiness into retrieving games and teaching them to carry objects

Irish Wolfhound Considerations

challengeSighthound Instincts

Despite their calm demeanor indoors, these are powerful hunters. Their prey drive is triggered by movement. A squirrel, cat, or small dog running across a field can trigger an explosive chase response that is nearly impossible to stop with verbal commands once engaged. They are generally with small running animals unless raised with them, and even then, instinct can override training.

challengeSeparation Anxiety

Wolfhounds are deeply bonding "velcro" dogs. They do not thrive in isolation and can suffer severe separation anxiety if left alone for long periods. This can manifest in destructive chewing, which, given their jaw size, can destroy drywall, furniture, and doors in minutes.

challengeAdolescent "Land Shark" Phase

Between 6 and 18 months, a Wolfhound is essentially a 100lb+ puppy with poor coordination and high energy. They can be mouthy and destructive. Their counter-surfing ability is unmatched; they can reach the back of kitchen counters without lifting their paws off the floor.

Portuguese Water Dog Considerations

dealbreakerVelcro Dog & Separation Anxiety

PWDs were bred to work on small fishing boats alongside their masters all day. They follow you into the bathroom and may develop severe separation anxiety if left alone 8+ hours. Prone to demand barking and whining if ignored.

challengeSevere Mouthiness & Nipping

As a retriever breed, they interact with the world through their mouths. PWD puppies are notoriously 'nippy' and oral—this is not aggression but can be painful and frightening for young children.

challengeThe 'Portie Greeting'

This breed is famous for dancing on hind legs and jumping up to greet faces. While charming to some, it's a significant fall risk for elderly owners or small children.

dealbreakerNon-Negotiable Grooming Costs

Professional grooming every 6-8 weeks at $100-150 is mandatory, not optional. Neglecting this leads to severe matting that damages skin and requires shave-down.

Portuguese Water Dog: Predatory sequence: Orient -> Eye -> Stalk -> Chase -> Grab-Bite. The Kill-Bite and Dissect phases are inhibited. This makes them generally safe with other dogs and often cats, though they may annoy them.

Irish Wolfhound: Irish Wolfhound puppies require consistent training and patience.

Portuguese Water Dog: PWD puppies are 'land sharks' - their retrieving instinct manifests as severe nipping and mouthing. Combined with high intelligence and energy, they require more management than a Golden Retriever (6/10) but less than a Malinois (9/10).
