Shichons are small-sized and basically non-shedding, but they have wavy, long-haired coats that can easily become matted or tangled. Shichon grooming, therefore, should be an easy but frequent task. Your Bichon-Shih Tzu mix will need brushing 4-5 times per week, monthly baths, and, depending on your preferred hairstyle, clipping or scissoring (either by you or a professional groomer) every 2-3 months.
To brush a Shichon: first wet the coat with mist from a spray bottle. You'll need both a slicker brush and a medium-toothed comb; starting with the head, use the slicker brush to work through the coat using the well-known line-brushing method. Use the comb to de-tangle stubborn mats. If you follow the brushing with a bath, use canine shampoo and conditioner (available at pet stores), then towel- or blow-dry the coat. Finish with another quick brush-through to neaten the coat.
Whether you cut the Shichon's hair yourself or have a groomer do it, these dogs need touchups every couple of months or so. Many owners learn to give their Shichons "mini-grooms," which simply consist of using clippers and/or scissors to trim the hair around the eyes (which, if too long, can obstruct and irritate the eyeballs), around the anus (to minimize that hair from getting dirty when the dog relieves itself), and on the paw pads (to give the dog better traction and decrease dirt/mud from collecting there). It's a good idea to visit a professional groomer at least once, as he or she can give you tips on how to groom a Bichon-Shih Tzu mix in general.
