Dogs with double coats have an undercoat and an outer coat.
The outer guard hairs serve to repel any moisture and they help get rid of any dirt whereas the softer undercoat acts more as an insulation that keeps dogs warm during the colder winter months and cooler when the weather is hot in the summertime. As such, a double coat should never be shaved because it takes away the barrier that protects dogs from the damaging UV rays of the sun.
Dogs with this type of coat tend to shed their undercoat several times each year, depending on the type of climate they live in.
Professional care of this coat type begins with the removal of the undercoat by using a Dog Rake.
If regular coat care has not been maintained by the pet’s owner severe matting can take place.
