Use a sucking mat, one you use in your own bath to stop you slipping. At the end of the day, stick it to the tiles on the wall around the bath. The drips will fall into the bath and not on the floor, making it dangerously slippery. If you have a nervous or fidgety dog in your salon, calm them down by rubbing your fingers above or between the eyes and nose of the dog. You will be amazed with the calming reaction you achieve.
Some dogs even start to fall asleep.
It won't calm all dogs down completely, but if you can have someone holding the dog and massaging its head you can get the job done with little stress to the dog or yourself. We are getting more smooth and short coated breeds into the salon nowadays. These breeds, such as Boxers, Labradors and Great Danes do not need a lot of grooming. But you could give them an extra spit and polish and send them out of your salon smelling lovely, with a beautiful glossy sheen. After a normal shampoo and condition, rub vigorously with a rubber curry comb or hound glove to loosen any dead hair and skin.
