All shampoos can be diluted with water in a bottle to help spread the shampoo further. Choose a good conditioning shampoo that won't dry out the fur even if used on a regular basis or buy a separate conditioner to add to the shampoo mix. Shampoo with Oatmeal or Aloe Vera help sooth irritated skin.
Never use human shampoo on a dog. It has a different PH balance and can cause skin issues. Never use washing up liquid. It will dry the coat and skin out too much and can cause skin issues.
Rinse your dog with water first to wash away dirt. When rinsing the head try to avoid getting water directly in the nose and ears. If using a shower head, wrap a cloth (i.e. tea towel, absorbent cloth) around the shower head to alleviate the pressure of water on the dogs head. The cloth on the shower head will also give you more accuracy around the nose area.
Apply shampoo from tail to head. Once shampoo is applied always rinse from head to tail. If shampoo has accidentally entered the eyes it will be the last to go in and first to be rinsed out.
When applying the shampoo from the diluted bottle or if using the shampoo neat, use a nylon body scrubber (the same we use in the shower, only please keep one just for your dog). It helps to spread the lather and remove dirt from the fur. Use your hands to shampoo your dogs head, ears and muzzle.
Once your dog has shampoo all over. Rinse from head to tail and repeat the process again. Always try and shampoo your dog twice. The first time helps to break down dirt and grease. The second time will help to clean the fur and skin. If your dog is extremely dirty then shampoo a third or fourth time if necessary or until the shampoo foam runs clean. With the final rinse, make sure all the shampoo is thoroughly washed off. Check under the base of the tail and armpits.
Once your dog is clean. Dry with an absorbent cloth or towel any excess water. Use a hairdryer on a low heat setting to partially dry the fur. For woolly or long coats, use a slicker brush to remove any knots or tangles. Use the hairdryer again on a low heat setting. Dry the remaining dampness from the fur. Use the slicker brush again and then go over with a metal comb to be sure all the knots are removed.
