The Portuguese water dog has a very specific and characteristic grooming that makes swimming easier. If not clipped, their wavy coat can develop knots especially when not dried properly. Water dogs have an inner and outer coat. The breed has variations of long, wavy hair (most common) and short, curly hair. Although black and black with white are the most seen, there are also cream, fawn and fawn with white.
Curly-haired ones have more problems with knots. It is recommended that these be brushed at least every two days. It is recommended to perform a grooming of the breed two to three times a year. As a working dog who loves the outdoors, the Portuguese water dog needs space and dedicated human parents who explore their adventurous side.
