Irish Water Spaniels shed very little, if at all, but they still must be brushed two to three times per week. Brushing removes dirt, prevents tangles and mats from forming and keeps the hair healthy. The natural oil in the dog's coat attracts dirt and debris, and regular brushing removes this dirt and distributes the oil throughout the hair to keep coat clean and healthy. The long, floppy, pendant ears of the Irish Water Spaniel do not allow for air to circulate properly through the ear, and when the dog swims, water can get trapped in the ear, making them prone to painful ear infections. After the dog has been in the water, and once or twice every week, clean the air with a cotton ball and a veterinarian-recommended cleanser. Brushing the teeth on a weekly basis will prevent tartar buildup, promote gum health and keep bad breath at bay. Trim nails once per month, if the dog does not naturally wear down the nails outdoors. If the toes click on hard floors, the nails are too long.
