When discussing dog coats, the terms hair and fur are often used interchangeably. However, there are distinct differences between the two, especially when it comes to texture, growth cycle, and grooming needs. If you’re a dog groomer, pet owner, or breeder, understanding these differences can help you care for a dog’s coat more effectively.
In this blog, we’ll break down the science behind dog hair and fur, explore which breeds have what type of coat, discuss the biological functions of a dog’s coat, and explain why it matters for grooming and maintenance.
The Science Behind Dog Hair vs. Fur
The primary distinction between dog hair and fur lies in the structure and growth cycle:
Hair grows continuously and has a longer growth cycle (anagen phase), meaning it sheds less frequently but requires regular grooming to prevent matting.
Fur has a shorter growth cycle (telogen phase), meaning it grows to a predetermined length and sheds more frequently, often in seasonal cycles.
Both hair and fur are made of keratin, the same protein that forms human hair and nails. However, their texture, length, and density vary based on the breed.
The Biological Functions of a Dog’s Coat
A dog’s coat is not just about appearance—it plays a crucial role in protecting and supporting the dog's health. Here are some key biological functions of a dog’s coat:
1. Barrier Protection
Hair and fur provide a physical, chemical, and antimicrobial barrier against the environment. The thicker the coat, the greater the level of protection from harmful substances and microorganisms that could penetrate the skin.
2. Camouflage
While camouflage is less important in domestic dogs, wild canines and other prey animals rely on coat colour to blend into their surroundings and avoid predators.
3. Communication
Coat colour and patterns can be used for communication. In some animals, coat markings can signal sex (sexual dimorphism) or dominance. For example, male lions with higher testosterone levels have darker, thicker manes.
4. Dispersal of Sebum
Sebaceous glands in the skin produce sebum, a natural oil that gets deposited onto the hairs within the follicle. Sebum helps to keep the coat waterproof and nourished, preventing excessive dryness.
5. Dispersal of Pheromones
Pheromones, secreted from specialised sweat and sebaceous glands, attach to hair shafts and help with communication between dogs. These chemical signals can influence behaviour, such as marking territory or signaling reproductive status.
6. Protection from UV Rays
The coat serves as a barrier against harmful UV rays, preventing sunburn and reducing the risk of skin damage. Dogs with thinner or lighter-coloured coats are more susceptible to sun exposure.
7. Sensory Function (Vibrissae – Whiskers)
Dogs have specialised hairs called vibrissae, also known as whiskers or sinus hairs. These thick, long hairs, found around the muzzle, eyes, and cheeks, are highly sensitive and provide dogs with essential sensory information about their surroundings.
8. Thermoregulation
Dogs rely on their coat for temperature regulation, with distinct seasonal changes:
Summer Coat:
Facilitates cooling by allowing heat to escape.
Usually has shorter, thicker hairs and fewer secondary hairs.
Allows heat to radiate from the body and escape between the hairs.
Winter Coat:
Facilitates heat conservation by trapping warm air close to the body.
Usually has longer and finer hairs with more secondary hairs.
The extra insulation keeps the dog warm in cold weather.
This natural adaptation helps dogs adjust to seasonal temperature changes.
Dog Breeds with Hair
Dogs with hair tend to have single-layered or lightly double-layered coats. Their hair grows continuously, making grooming a crucial part of their care. These breeds typically require regular brushing and trims to prevent matting and overgrowth.
Examples of Breeds with Hair:
Poodles – Known for their curly, dense hair that requires regular grooming to prevent matting.
Shih Tzus – Their long, flowing hair grows continuously and needs frequent trims.
Yorkshire Terriers – Have silky, fine hair similar to human hair, requiring daily brushing.
Maltese – Possess long, straight, silky hair that doesn’t shed much but needs regular maintenance.
Portuguese Water Dogs – Feature wavy or curly hair that requires scissoring or clipping to keep it manageable.
Grooming Needs for Hair Coats
Since hair grows continuously, these breeds benefit from professional grooming every 4-8 weeks. Regular brushing is essential to prevent tangles and mats, and coat conditioning helps maintain texture and shine.
Dog Breeds with Fur
Dogs with fur typically have a double coat consisting of:
A soft, dense undercoat that provides insulation.
A coarse, protective topcoat that repels dirt and water.
These breeds tend to shed seasonally, often experiencing heavier shedding in spring and autumn as they adjust to temperature changes.
Examples of Breeds with Fur:
Labrador Retrievers – Have a dense double coat that sheds seasonally.
German Shepherds – Feature a thick undercoat that sheds heavily, requiring regular deshedding.
Siberian Huskies – Possess a water-resistant coat that helps them thrive in cold climates.
Golden Retrievers – Have a wavy outer coat and a thick undercoat that requires frequent brushing.
Alaskan Malamutes – Have one of the thickest double coats, built for extreme cold.
Grooming Needs for Fur Coats
Breeds with fur require frequent brushing, especially during shedding seasons. Deshedding tools and undercoat rakes are essential for managing their coat, and occasional baths help remove excess loose fur.
Why It Matters: Hair vs. Fur in Grooming & Care
1. Shedding Differences
Hair-coated dogs shed minimally but require frequent grooming.
Fur-coated dogs shed seasonally, making deshedding tools crucial.
2. Allergies
Hair-coated breeds are often preferred by allergy sufferers since they shed less dander.
Fur-coated breeds shed more dander, which can trigger allergies.
3. Climate Considerations
Dogs with double coats (fur) are naturally insulated, making them well-suited for colder climates.
Single-coated dogs (hair) may need extra protection in winter, such as coats or sweaters.
4. Grooming Frequency
Dogs with hair require trims every 4-8 weeks.
Dogs with fur need frequent brushing, especially in shedding seasons, but rarely need full-body trims.
Final Thoughts
Understanding the difference between dog hair and fur is essential for providing the best care for your pet. Whether you have a Poodle with a curly coat that requires trims or a Labrador Retriever that sheds seasonally, knowing how to maintain their coat ensures their comfort and health.
