Using a sink to wash your dog is perfect for small breeds and puppies. A sink puts your dog at your waist level instead of bending over to reach into a tub. Your kitchen sink may also have a handheld shower faucet to make getting your dog wet and rinsing shampoo a much simpler task than using a cup or bowl for rinsing. Sinks can come with challenges, however, so always be careful when you place your dog in a sink for a bath. Don't ever leave him unattended that high up with the ability to jump out of the sink and down to the floor.
When it comes to bathing in general your dog may be excited, or you may not be excited. He may also be a bit nervous to be up so high, especially if this is something he's not used to doing. Ease his mind by giving him treats and prepare before bath time starts so you can address any challenges which may arise. Utilize the ease of the sink and make that time quick and easy for your pup.
