The grooming needs of a Portuguese Water Dog are moderately demanding due to their dense, waterproof coat. Regular brushing, at least a few times a week, is necessary to prevent matting and to keep the coat healthy and looking its best. Professional grooming every six to eight weeks is also recommended to trim the hair and maintain the shape of the coat. Since they are frequent swimmers, care should be taken to clean and dry their ears thoroughly after water activities to prevent infections. Attention to grooming not only keeps the Portuguese Water Dog looking sharp but also supports their overall health by preventing skin issues and promoting good hygiene.
