Why is my senior dog shedding more than usual?

Overview
If your senior dog is shedding more than usual, it can be due to normal coat changes, seasonal moulting, grooming routines, dry skin, diet changes or an underlying health issue. Some older dogs also groom less well, which can make loose hair build up quickly.
It’s worth checking the coat and skin closely first. If the shedding is sudden, patchy, linked to itching or comes with other changes such as low energy, weight loss or skin irritation, a vet check is sensible.
Things To Check
1. Look at whether the shedding is all over the body or focused in one area, such as the back, belly, tail or ears.
2. Check for skin changes like redness, dandruff, scabs, flakes, oily patches, soreness or areas that feel hot.
3. Notice whether your dog is scratching, licking, chewing or rubbing more than usual.
4. Think about any recent changes in food, treats, medication, bedding, shampoo or grooming routine.
5. Check whether the coat feels unusually dry, greasy, dull or thin compared with normal.
6. See whether there are other changes such as weight loss, more drinking, reduced appetite, stiffness or lower energy.
7. Work out whether the shedding is seasonal or whether it has continued for several weeks without easing.
Common Causes
Seasonal moulting is still one of the most common reasons, even in older dogs. Some breeds shed heavily year-round, while others seem to cast more coat at certain times of year.
Dry skin, poor grooming or a coat that is not being brushed through properly can also make loose hair more noticeable. Senior dogs may struggle a bit more with self-grooming, especially if they are stiff or less active.
Diet changes, weight changes or a less balanced routine can affect coat quality. Older dogs can also develop skin problems, allergies, parasites or hormone-related conditions that may lead to increased shedding or a poor coat.
What To Do
Start with gentle, regular brushing to remove loose coat and help you spot skin changes early. Choose a brush that suits your dog’s coat type so you’re not irritating the skin.
Keep an eye on the skin as you groom. If you notice dandruff, redness, soreness or bald patches, note where they are and whether they’re getting worse.
Stick to a steady feeding routine and make sure your dog is eating well and drinking normally. If you’ve changed food recently, think about whether the timing fits with the increased shedding.
Reduce anything that could dry the coat out, such as over-washing with harsh shampoo, and use a routine that suits older skin and coat care needs.
If the shedding is persistent, marked or out of character for your dog, book a vet check so they can look for skin disease, parasites, hormone issues or other health causes.
