Why Does My Dog Shed More After Being Brushed?

Read time: 3 minutes
Overview
It’s very common for a dog to seem to shed more after being brushed. In many cases, the brush is simply removing loose hair that was already ready to come out, so it can look worse even though it’s part of normal coat maintenance.
If the shedding seems heavier than usual, or your dog’s skin looks uncomfortable, there may be another reason too. Coat type, brushing technique, seasonal moulting and skin irritation can all make a difference.
Things To Check
1. Check whether the extra shedding only happens after brushing, or whether you’re also finding more hair on the sofa, bedding or in your car.
2. Look closely for redness, flakes, scabs, dandruff, broken skin, soreness or bald patches where the coat has been brushed.
3. Feel the coat to see whether it’s loose, knotty, greasy, dry or woolly, as coat texture can affect how much hair comes away.
4. Notice whether your dog seems itchy, is scratching more, licking the same area or rubbing against furniture.
5. Check whether the brush is pulling hard, catching on tangles or bringing out large clumps, which can happen if the coat is matted or the wrong brush is being used.
6. Think about the timing. Seasonal moulting, changes in indoor heating, recent washing or a move from winter to spring can all increase loose hair.
7. Look for changes in general health, such as reduced appetite, low energy, weight loss or a coat that seems thinner overall.
Common Causes
The most common reason is normal shedding. Brushing loosens hairs that were already in the resting phase of the coat, so you notice them all at once rather than gradually.
Seasonal moulting is another very common cause, especially in spring and autumn. Some dogs also shed more when they spend time in warm, centrally heated homes.
Brushing technique can make a big difference. A brush that’s too harsh, too fine for the coat type, or used on a tangled coat may pull out more hair than expected.
Dry skin, mild irritation or sensitivity can also increase shedding and make the coat look less settled. In some dogs, allergies or skin parasites can contribute too, usually alongside itchiness or visible skin changes.
Less commonly, coat changes can be linked to underlying health issues, especially if the shedding is sudden, widespread or paired with other symptoms.
What To Do
Brush gently and regularly rather than trying to remove everything in one go. Short, calm sessions are often better than heavy brushing that irritates the skin.
Use a brush that suits your dog’s coat type and stop if you notice pulling, discomfort or skin redness. If the coat is tangled, work through it carefully or get help rather than forcing the brush through.
Keep an eye on whether the shedding settles after a few grooming sessions or whether it keeps increasing. A simple note of when it happens, how much coat is coming out and whether the skin looks normal can help you spot a pattern.
If your dog has dry skin, a sensitive coat or lots of loose hair, a steady grooming routine and sensible washing schedule may help keep the coat more comfortable and easier to manage.
When To Contact A Vet
Speak to your vet if the shedding is sudden, very heavy, patchy, or happening alongside itching, redness, scabs, pain, a dull coat or changes in your dog’s general health. These signs can point to an underlying skin or health problem that needs proper assessment.
Products That May Help
If brushing is bringing out a lot of loose coat, a gentle grooming routine can help keep things more manageable and support regular coat care at home.
