Double-coated Dogs:
Certain breeds like Golden Retrievers, German Shepherds, Labrador Retrievers, Siberian Huskies, Border Collies and Chow Chows have a double coat consisting of a soft undercoat close to their skin and a thick outer coat with longer hair. They shed their undercoat twice a year, in summer and winter, while the outer coat sheds less frequently. The undercoat plays a crucial role in regulating temperature, acting as insulation to keep them cool in summer by trapping cool air next to their skin and preventing excessive heat absorption.
Shaving these double-coated and often long-haired dogs might seem like the obvious solution for keeping dogs cool in summer, but it disrupts their natural cooling mechanism. It exposes their sensitive skin to harmful UV rays, increasing the risk of sunburn and heat-related illnesses. Additionally, shaving can hinder the regrowth of the undercoat, leaving the dog vulnerable to overheating and sunburn in the long term. It can also cause long-term damage by altering the growth patterns of their hair, leading to potential overcrowding of the undercoat and susceptibility to skin issues.
Single-coated Dogs:
Some dog breeds including certain Indie dogs, Poodles, Maltese, Bulldogs, etc. possess a single coat of dog fur with either short or long hair with no soft undercoat. These dogs should not be shaved down to their skin either as the fur protects them from sunburn, skin cancer, and bug bites. These dogs don’t have the added insulation of an undercoat, so they need their fur for protection.
