The Portuguese Water Dog was bred to work in the sea — herding fish into nets, retrieving tackle and carrying messages between boats — and its coat is a single, dense layer of curls or waves with no undercoat to shed. That sounds low-maintenance and is not: the coat grows continuously, traps whatever the dog swims through, and mats with enthusiasm. Your tool kit is built around deep combing and regular clipping.
Combing Tools for a Coat With No Undercoat
A firm slicker brush opens the curls and lifts out debris, but the essential tool is a long-toothed stainless steel comb, because its teeth are long enough to travel the full depth of a thick Portuguese Water Dog coat and reach the skin. Brush a section, then comb it; where the comb stops, a mat is starting. The breed's classic mat zones are behind the ears, under the collar, in the armpits, along the belly, at the base of the tail and anywhere a harness or life jacket rubs during the swimming this dog lives for. A mat splitter or dematting comb lets you slice a forming mat into strips that can be teased apart with your fingers and the comb, saving coat that would otherwise have to be clipped out. Rounded-tip scissors are for careful work around the eyes — many owners keep the face trimmed so the dog can actually see — and for trimming hair between the paw pads, where it collects sand and ice.
Clippers and the Two Traditional Clips
Most Portuguese Water Dogs are kept in one of two clips: the retriever clip, a fairly even shorter length all over, or the lion clip, with the muzzle, middle body and hindquarters clipped close and the chest and tail left full. Either way, electric clippers with a range of guard combs are a core part of the home kit, used to maintain length between professional grooms, clear the sanitary areas and shorten a coat that has gotten away from you. Work on a clean, dry, thoroughly combed coat; clipping through mats forces the blade under felted hair against the skin and is the classic way this breed gets nicked. If the coat is badly matted, the kindest reset is a short clip all over and a fresh start on the combing routine, rather than hours of painful dematting.
A Working Dog's Bath and Dry Routine
Dry with a dryer on a cool or warm setting while combing through, because air-drying a thick coat leaves the roots damp for hours and the skin underneath can turn itchy and smelly. Check the ears after swimming days: this breed grows hair in the ear canal and spends its life getting its head wet, a combination that rewards a weekly look and wipe. Note any head shaking or ear odour and mention it to your veterinarian if it keeps returning.
Feet, Nails and the Active-Dog Checks
Webbed feet and a life of launching off docks mean nails and paw pads work hard. Trim nails regularly and inspect pads for cuts and cracks after rocky shore days, and keep the hair between the pads short so the dog grips rather than skates on smooth floors at home. While combing, run your hands over the whole dog: the breed's coat is thick enough to hide ticks, small lumps and burrs completely, and the comb-and-feel pass is often how owners find them early.
Keeping Up With a Coat That Never Stops
The Portuguese Water Dog's coat grows whether or not anyone keeps up with it, so the routine — comb-outs, ear checks, clip maintenance — has to survive busy weeks and holidays rather than depending on one person's free Sunday. Putting each job on a shared rota, with notes about this dog's mat zones and the clip length you keep, means a partner or family member can step in without guessing. KinsLe Care Teams supports exactly that for your Portuguese Water Dog, turning comb-outs and clip-downs into assigned duties that are ticked off with a timestamp as they happen.
