Lagotto Romagnolo vs Spanish Water Dog: two curly Mediterranean workers with different day jobs

Both breeds descend from curly coated European water dogs and share a low shedding coat, but the Lagotto found a second career hunting truffles while the Spanish Water Dog stayed closer to its herding and fishing roots, and their coats are cared for in opposite ways.

Working history

The Lagotto Romagnolo began as a marsh retriever in northeastern Italy, fetching waterfowl from the lagoons around Comacchio, and when those wetlands were drained in the 1800s the breed found new purpose hunting truffles in the hills of Romagna, a job it still does today. The Spanish Water Dog worked more broadly, herding flocks of sheep and goats along seasonal routes in Andalusia and helping fishermen on Spain's northern coast, giving it a dual herding and working water dog background rather than one specialized task.

Coat care, opposite approaches

This is the most practical difference between the two breeds. A Lagotto's tight, woolly curls are combed gently and clipped every two to three months, with careful attention to avoid fluffing the coat out of its natural ringlets. A Spanish Water Dog's coat should never be brushed at all, since brushing pulls the curls apart and causes matting; instead it is either clipped to an even length once or twice a year or allowed to grow into natural cords that are separated by hand as they form. Anyone drawn to natural corded coats should look at the Spanish Water Dog specifically.

Temperament with strangers

Spanish Water Dogs are generally more reserved and watchful with people they do not know, a trait that came directly from their herding and guarding work, and many make decent informal watchdogs as a result. Lagotti are also somewhat reserved but tend to be a bit more openly affectionate and eager to be involved once they know you, closer to a companion dog with a working nose than a true guardian breed. Both need solid early socialization to avoid excessive wariness as adults.

Exercise and mental work

Both breeds thrive on activities that use the nose, since both were selected for scent and search ability, whether finding truffles or working alongside herders and fishermen. A Lagotto particularly benefits from nosework and truffle detection style games, which many trainers now offer as a pet friendly sport. A Spanish Water Dog enjoys similar scent games alongside herding practice, agility and swimming, and both breeds need 60 to 90 minutes of daily activity with real mental engagement built in.

Health and lifespan

Lagotti often live an unusually long time for their size, typically 14 to 16 years, though the breed carries a benign form of juvenile epilepsy that usually appears very young and fades by around three months, along with hip and elbow dysplasia and a rare inherited condition called lysosomal storage disease. Spanish Water Dogs typically live 12 to 14 years and are known for hip dysplasia, hypothyroidism and progressive retinal atrophy, along with two inherited conditions with DNA tests available, congenital hypothyroidism with goiter and a nervous system disorder called neuroaxonal dystrophy.

Availability and cost

Both breeds remain relatively uncommon outside their home countries and dedicated fan communities, so buyers in most regions should expect a genuine search, some travel and a meaningful price for a well bred, health tested puppy of either dog. Truffle hunting Lagotti with proven working lines can command a particular premium among buyers specifically interested in that skill, sometimes considerably more than a companion bred puppy of the same breed.

Grooming costs favor the Spanish Water Dog slightly for owners who choose the corded route, since cords need separating by hand rather than regular professional clipping, though many pet owners of either breed still prefer a simple clip a few times a year for practicality. Feeding costs are similar given the breeds' overlapping size ranges, typically 190 to 320 g of dry food a day depending on the individual dog's size and activity level.

Anyone drawn to either breed's low shedding coat and genuine working intelligence should weigh the Lagotto's slightly more affectionate, companionable nature against the Spanish Water Dog's stronger herding and guarding instincts before choosing which working heritage fits their household better. Both dogs settle well into active family life once their scent based mental needs are consistently met. Both remain rewarding, healthy choices for owners genuinely willing to research and commit to a less common breed.

Choose the Lagotto Romagnolo if

  • Notably long average lifespan for a medium sized dog
  • Fascinating and genuinely useful truffle hunting ability
  • Slightly more openly affectionate temperament
  • Distinctive ring shaped curls kept trim with regular clipping

Choose the Spanish Water Dog if

  • Low maintenance coat option through natural corded growth
  • Strong, versatile herding and working instincts
  • More naturally watchful, useful as an informal alert dog
  • Slightly larger, sturdier build
Can both Lagotto Romagnolos and Spanish Water Dogs be brushed the same way?

No, and this is an important difference. A Lagotto's coat should be combed gently and regularly to maintain its tight curls, while a Spanish Water Dog's coat should never be brushed at all, since brushing pulls apart its natural curls and causes matting. Spanish Water Dog coats are instead clipped short or allowed to form cords that are separated by hand as they develop.

Which breed lives longer, Lagotto Romagnolo or Spanish Water Dog?

Lagotti often have the edge here, with a typical lifespan of 14 to 16 years compared with 12 to 14 for the Spanish Water Dog. Both are generally healthy breeds for their size, and actual lifespan for any individual dog depends heavily on genetics, weight management and overall care rather than breed averages alone.

Are Lagotto Romagnolos or Spanish Water Dogs better for a first time owner with allergies in the household?

Both breeds shed very little and are popular choices for people managing mild dog allergies, since loose hair stays trapped in the curls rather than falling around the house. Neither is completely allergen free, so spending time with adult dogs of either breed before committing is the most reliable way to judge an individual reaction.
