A good rule of thumb is to not shave any dog that sheds, particularly double-coated breeds. Dogs with this coat type, such as the Alaskan husky, Pomeranian, Australian shepherd and Pembroke Welsh corgi, have both a downy, insulative undercoat and longer, protective outer “guard hairs” to repel moisture. These dogs will naturally shed, according to Dr. Chris Reeder, veterinary dermatologist with BluePearl Veterinary Partners, so that they have a lighter-weight coat in the summer; this means you may notice more fur on your pillows and sofa as the warm weather approaches.
“Some folks shave dogs and cats to help cut down on shedding, which is driven by the number of daylight hours,” Dr. Reeder tells The Dodo. During the summertime, longer days will mean more shedding, whereas in the winter, when the days are shorter, dogs and cats are more likely to retain their coats, Dr. Reeder explains.
However, shaving your pet because the long summer days are making your cat or dog release a little extra fur could do some serious damage to their lustrous, thick coats.
