These dogs' short- to medium-length, dense, wiry coats don't require a ton of care, so Irish Terrier grooming isn't too time-consuming overall. Breed members shed very little, and their coats don't mat or tangle much, so they'll need brushing once or twice a week to keep their coats looking healthy and clean. Baths are recommended about every six weeks (or if the dog becomes especially dirty or stinky). And while Irish Terriers can have their coats clipped (which would need to be done every 2-3 months), many breed owners, particularly those who show their dogs, prefer to strip them either by hand or with a stripping knife. Stripping would be required about four times per year.
A firm bristle brush works best for brushing these dogs. To brush an Irish Terrier: first wet the coat with mist from a spray bottle, then brush the coat section by section, moving in the direction of hair growth; if you encounter a stubborn tangle or mat, first try separating it with your fingers, then finish working through it with the brush.
If you're following the brushing with a bath (and most dog breeds should be brushed prior to bathing): either a bathtub or an outdoor kiddie pool and a garden hose will work. Be sure to use canine shampoo, as the human kind can irritate a dog's skin and make it itchy. First wet the coat, then apply a quarter-sized amount of shampoo to the dog's back; lather well and work downward (and don't forget the legs!). Rinse thoroughly, towel-dry, then finish with another quick brush-through to make the coat look neat and clean.
Both clipping and stripping the Irish Terrier coat (discussed in more detail in the Plucking & Stripping and the Styling & Haircuts sections) can be done at home, but it's a good idea to visit a professional groomer at least once. The groomer can demonstrate how the clipping or stripping should be done, and can provide tips on how to groom an Irish Terrier in general.
