Australian Shepherd vs Portuguese Water Dog — Breed Comparison

About the Australian Shepherd

Despite its name, the Australian Shepherd was actually developed in the western United States during the 19th century, likely from Basque shepherd dogs that passed through Australia on their way to America. These versatile herding dogs stand 18–23 inches tall and weigh 40–65 pounds, with a medium-length double coat that comes in four recognized colors — black, blue merle, red, and red merle — often with striking copper and white markings. Their coats are weather-resistant and require regular brushing to manage moderate-to-heavy shedding.

Temperament & Personality

Australian Shepherds are brilliant, energetic, and deeply devoted to their families — they thrive when given a purpose and can become anxious or destructive without one. They are excellent with children, often naturally herding and watching over younger family members. Aussies are typically friendly with other dogs but can be reserved with strangers, and their intelligence makes them exceptionally responsive to training.

Pros

One of the most intelligent and trainable breeds — excels in agility, flyball, and herding
Loyal and affectionate family companion who bonds closely with all household members
Versatile working dog adaptable to ranch life, sport, or active suburban living
Beautiful, eye-catching coat with striking color variations including heterochromia

Cons

Demands extensive daily exercise and mental engagement — easily 1–2 hours minimum
Heavy shedding, especially during seasonal coat changes
May herd children, cats, and other pets by nipping at heels
Prone to epilepsy, hip dysplasia, and the MDR1 gene mutation affecting drug sensitivity

About the Portuguese Water Dog

The Portuguese Water Dog was developed centuries ago along Portugal's coast, where it served as an indispensable fisherman's companion — herding fish into nets, retrieving lost tackle, and swimming messages between boats. These robust, medium-sized dogs stand 17 to 23 inches tall and weigh 35 to 60 pounds, with a strong, muscular build optimized for swimming. Their coat comes in two varieties — curly or wavy — in black, white, brown, or combinations thereof, and grows continuously like human hair rather than shedding seasonally.

Temperament & Personality

Portuguese Water Dogs are spirited, obedient, and deeply bonded to their families — they thrive on being included in activities and do not do well relegated to the backyard. They are playful and patient with children, typically friendly with other dogs, and possess an enthusiasm for life that is both infectious and demanding. Their intelligence and eagerness to work make them highly trainable, though they need a job or purpose to remain content.

Pros

Low-shedding, hypoallergenic-type coat suitable for many allergy sufferers
Outstanding swimming ability and love of water activities
Highly trainable, biddable, and eager to please
Robust health with a lifespan of 11 to 13 years

Cons

High exercise demands — needs vigorous daily activity including swimming when possible
Coat requires regular professional grooming every 4 to 6 weeks
Can become mouthy and destructive if under-stimulated or left alone too long
Prone to hip dysplasia, progressive retinal atrophy, and GM1 storage disease
