Overview
Dog shedding is not normal when it suddenly increases, becomes patchy, or comes with skin irritation, bald spots, dandruff, odour, or a change in your dog's behaviour. Some shedding is part of normal coat change, but excessive shedding can have several causes, from grooming and diet to stress, parasites or skin problems.
Things To Check
1. Check whether the shedding is seasonal or has started suddenly, especially after a change in weather, routine, diet or bedding.
2. Look closely for red skin, scabs, flakes, broken hair, bald patches, sores or a greasy or greasy-feeling coat.
3. Run your hands through the coat to see if your dog seems itchy, sensitive, uncomfortable or is scratching, licking or rubbing more than usual.
4. Check for fleas, flea dirt, ticks or signs of other parasites, especially around the tail base, belly, ears and neck.
5. Notice whether the coat is thinner in one area or all over, as patchy loss can suggest a different issue from normal shedding.
6. Think about whether the grooming routine has changed, because infrequent brushing or the wrong brush for the coat type can make loose hair build up.
7. Watch for other changes such as low energy, weight loss, thirst, appetite changes or general unwellness.
Common Causes
The most common cause is normal coat change, especially in spring and autumn, or loose undercoat that is being shed more noticeably.
Another common reason is grooming factors, such as not brushing often enough, using a brush that does not suit the coat, or bathing too much or too little.
Skin irritation can also lead to extra shedding. This may happen with fleas, allergies, dry skin or mild skin infection.
Stress, changes in routine or a poor-quality diet can sometimes affect coat condition and increase hair loss.
Less commonly, hormonal or other health problems may affect the coat, especially if the shedding is ongoing, severe or linked with other symptoms.
What To Do
Start by brushing your dog regularly with a grooming tool suited to their coat type and note whether the shedding is improving or getting worse.
Keep a simple record of when it happens, how much hair you're seeing and whether there are any skin changes, itching or other symptoms.
Check your dog's flea control is up to date, and keep their bedding clean so you're not missing skin irritation or parasites.
Make sure their diet is consistent and appropriate for their life stage, and avoid sudden changes unless you've planned them carefully.
If the coat seems dry, dull or the dog dislikes grooming, use a gentle approach and avoid over-washing or harsh products.
When To Contact A Vet
Speak to your vet if the shedding is sudden, patchy or severe, or if it comes with itching, redness, sores, bad smell, pain, weight loss, lethargy or other signs that your dog isn't quite right. It's also sensible to get advice if the coat is changing over time and home grooming isn't helping.
Products That May Help
If your dog is shedding more than usual, gentle coat care and regular washing can help with routine grooming and make it easier to keep an eye on skin and coat changes.
