Clean
A full bath every four to eight weeks for most dogs, with a gentle wash formulated for dog skin, rinsed thoroughly and dried to the skin. In between, wipes for paws, legs and faces, and a damp cloth for the occasional dirty patch. The aim is a clean dog, not a frequently washed one.
Protect
The parts of a dog that meet the world hardest are its paws and nose. In cold, salted or very dry conditions, a thin layer of balm on clean pads in the evening keeps them supple, and a grain of the same on a rough nose does the same. In summer, shade and, if needed, pet-safe sun protection for pale noses.
Maintain
Brushing, several times a week for long coats and once or twice for short ones, does more for skin and coat than any product. A light detangling mist makes it easier on long coats. Drying after wet walks prevents the damp-skin problems that account for many vet visits. And a weekly look over the skin, in good light, catches most things early.
What to leave out
Fragrance, essential oils, human products and anything applied because the bottle looked nice. Fewer products, used well, beat a shelf full of them.
When routine is not enough
Persistent itching, red or broken skin, hair loss, a strong smell or sudden changes are not routine matters. A vet should see those first. Routine care then supports whatever they recommend.
