Overview
If your dog seems to be moulting non-stop, it’s often due to normal coat changes, breed type, grooming habits, or something that’s irritating the skin. Some dogs shed heavily all year, while others seem to drop more coat at certain times or when their routine changes.
The key is to look for patterns and any signs that the shedding is more than normal coat loss. Heavy moulting on its own is often manageable, but shedding alongside itchiness, dandruff, redness or thinning patches can point to a skin or coat issue that may need attention.
Things To Check
1. Check whether the shedding is seasonal or has been going on steadily for weeks or months.
2. Look closely for redness, scabs, dandruff, broken skin, bald patches or any greasy or flaky areas.
3. Notice whether your dog is scratching, licking, rubbing or biting at the skin more than usual.
4. Check if the coat is being brushed regularly, and whether loose hair seems to be building up between grooming sessions.
5. Think about any recent changes in diet, washing routine, bedding, household cleaners or walking routes.
6. Check for fleas or flea dirt, especially around the tail base, belly and neck.
7. See whether the coat looks dull, thin or patchy compared with your dog’s usual appearance.
Common Causes
Normal seasonal moulting is the most common reason, especially in double-coated breeds or dogs with thick coats. Some dogs simply shed a lot more than others, and indoor heating can sometimes make shedding seem more constant.
Infrequent grooming can make loose coat build up and come out in larger amounts, which can feel like non-stop moulting. Brushing habits, coat type and whether the undercoat is being removed properly all make a difference.
Skin irritation is another common reason. Fleas, dry skin, allergies, reactions to washing products or general skin sensitivity can all lead to extra shedding, especially if your dog is also itchy or uncomfortable.
Less commonly, coat changes can be linked with underlying health issues such as hormone-related conditions or other skin problems. These are more likely if the shedding comes with thinning coat, bald patches, changes in skin condition or a general change in how your dog is feeling.
What To Do
Start by brushing your dog more regularly for a short period and see whether the amount of loose coat settles. Use a grooming routine that suits their coat type, and make sure you’re not brushing so hard that the skin gets irritated.
Keep an eye on the skin as well as the hair. If you notice itching, dandruff or sore areas, avoid changing lots of things at once. It’s usually better to keep a simple routine while you work out what’s going on.
Check for fleas and keep notes on when the shedding seems worst, as that can help you spot patterns linked to weather, exercise, washing or indoor conditions. If your dog is otherwise well, this kind of monitoring is often the best first step.
If the coat is dry, greasy or hard to manage, gentle washing and regular grooming may help support coat condition as part of your normal care routine.
