Why dogs shed (and what is normal)
Shedding is the normal replacement of old or damaged hair. Almost every dog sheds to some degree, though the amount varies a lot. Breeds with a thick double coat, such as many shepherds, retrievers, and northern breeds, tend to shed heavily. Dogs with continuously growing hair, such as poodles and some terriers, usually leave less hair around the house, but their coats can mat if they are not brushed.
Because shedding is a normal process, the realistic goal is to manage it rather than stop it. Regular grooming, a suitable diet, and a bit of housekeeping make the biggest difference.
What triggers a dog to start shedding?
Several things influence how much and when a dog sheds:
- Season and daylight. Many dogs lose more hair as the seasons change.
- Coat type and breed. Double-coated dogs generally shed more than single-coated dogs.
- Hormonal and life changes. Pregnancy, nursing, and a puppy losing its first coat can all bring noticeable shedding.
- Indoor living. Dogs kept in climate-controlled homes may shed more evenly through the year.
- Skin problems, parasites, allergies, or illness. These can cause hair loss that looks like heavy shedding but is not normal (see below).
- Stress. Some dogs lose more hair around stressful events, such as a vet visit.
What months are the worst for dog shedding?
There is no single answer, because it depends on the dog, the climate, and whether the dog lives mostly indoors. Many owners notice the heaviest shedding in spring and in autumn, as dogs change between lighter and heavier coats. If your dog is a heavy shedder, it is reasonable to plan for extra brushing during those transition periods. Watching your own dog’s pattern for a year or two will tell you more than any general calendar.
Do dogs ever quit shedding?
Generally no. Dogs replace hair throughout life, so some shedding is expected at any age. Low-shedding breeds shed less, but “non-shedding” is better thought of as “sheds very little.” If a dog’s shedding suddenly stops, or if hair is being lost in patches rather than evenly, mention it to your vet.
Brushing: the foundation of shedding control
Brushing removes loose hair before it lands on your furniture and helps spread natural skin oils through the coat. A few general guidelines:
- Short, smooth coats: a rubber curry brush or grooming mitt works well.
- Medium to long coats: a pin brush or slicker brush, followed by a comb to check for tangles.
- Thick double coats: an undercoat rake or deshedding tool, used gently, can remove loose undercoat. Go slowly and avoid pressing hard on the skin.
- Curly or wavy coats: a slicker brush and a comb, working down to the skin so mats do not form.
How often depends on the coat. Heavy shedders often benefit from brushing several times a week during peak shedding, while short-coated dogs may need less. Keep sessions calm and short, with treats if your dog is nervous. If you find mats, sore spots, or skin that looks red or flaky, stop and have it checked rather than brushing through it.
What do groomers do to deshed a dog?
A professional deshedding service usually combines several steps:
- A thorough bath, often with a conditioner or a shedding-focused shampoo.
- Forced-air drying, which blows loose undercoat out of the coat.
- Brushing and raking with deshedding tools to remove the loosened hair.
- Trimming problem areas such as sanitary areas, if needed.
This can remove a large amount of loose hair in one visit, but it does not stop the coat from growing and shedding again. Ask the groomer what they use and how often they suggest returning. If your dog has skin problems, tell the groomer beforehand.
Bathing and drying to loosen dead coat
A bath can help release loose hair, especially if followed by a thorough brush-out. Use a shampoo made for dogs and rinse completely. Brush before the bath to remove tangles, since water can tighten mats. Dry the coat well, including the undercoat. For product cautions, see our guide to dog shampoos to avoid.
Bathing too often can dry out some dogs’ skin, so ask your vet or groomer how often is appropriate for your dog’s coat and skin.
Diet, hydration, and coat health
A complete and balanced diet supports healthy skin and coat (see dog food for a long life). Fresh water should always be available; our guide on how to hydrate a dog has tips for dogs that drink too little. If your dog’s coat looks dull, dry, or thin, do not assume a supplement is the fix. Poor coat quality can reflect an underlying health problem, and supplements are not appropriate for every dog. Talk with your vet before adding supplements or changing diets, especially if your dog also has weight changes (see dog weight loss and hair loss).
Should you shave a shedding dog?
Shaving a double-coated dog is often discouraged by groomers and vets. The coat helps with insulation and protection from the sun, and shaved hair may grow back unevenly. It also does not stop shedding. A trim for a medical reason or a matted coat is a different matter, and your groomer or vet can advise.
Managing hair at home
- Vacuum often with a cleaner designed to pick up pet hair.
- Wash dog bedding regularly.
- Use washable throws on favorite furniture.
- Brush outside when weather permits.
- Keep a lint roller near the door.

When shedding is a health problem
See your vet if you notice:
- Bald patches, thinning areas, or uneven hair loss
- Red, inflamed, scabby, or flaky skin
- Intense scratching, licking, or chewing
- A dull, brittle coat along with other changes in energy, appetite, or weight
- Hair loss together with weight loss
- Sudden, dramatic increase in shedding
Parasites, allergies, skin infections, hormonal conditions, and other illnesses can all affect the coat. A vet can examine your dog and decide what testing or treatment is needed. If hair loss is paired with weight changes, read about what connects dog weight loss and hair loss.
Quick takeaways
- Shedding is normal, and the aim is to manage it.
- Brush with tools suited to your dog’s coat.
- Professional deshedding helps, but it is temporary.
- Avoid shaving double-coated dogs unless advised.
- Bald patches, irritated skin, or other symptoms deserve a vet visit.
