1
Soak the dog
Warm water. Get them properly wet, not just damp. Avoid the eyes.
2
Squeeze it on
A good line down the back. More for big dogs. The bottle does the work — no need to wrestle the cap.
3
Lather everywhere
Both hands, fingers through the coat to the skin. Don't forget under the chin and the back legs.
4
Rinse till clear
Until the water runs clean. Stand back. Let them shake. You will get wet. That's the deal.
