According to Samantha Woodlands, owner and operator of Doggie Wash Boutique in San Diego, California getting wax or any sticky substance out of a dog's hair is time consuming but fairly simple. Woodlands states that not all breeds of dogs have the same texture and therefore some dog hair will respond differently than others when trying to remove wax. In general, however, the same wax removal technique is widely used in the dog grooming community.
How to Get Wax Out of Dog Hair
Hold your dog in a comfortable position on surface that will discourage slipping if he moves. An elevated surface, such as a counter top or even the seat of the couch will help reduce pressure on your back if the process turns into a lengthy one.
Soak a cotton ball with mineral or baby oil. Rub the cotton ball over the hair that has wax in it. Make sure the hair and wax is thoroughly coated with oil.
Use a wide-toothed metal grooming comb to work through the wax-coated hair. The oil will work to loosen the wax while you are combing.
Repeat this process until the hair has broken free from the wax.
Bathe your dog to wash away excess wax and oil.
