Overview
If your dog has a dull coat and dandruff-like flakes, the first things to check are skin irritation, grooming routine, diet, and whether there may be parasites or another skin problem. It could be something fairly simple, but there are several possible causes, so it’s best to look closely rather than assume it’s just dry skin.
Things To Check
1. Part the coat in a few places and look for flakes, redness, scabs, broken hair or sore spots.
2. Check whether the skin looks greasy, very dry, or has a strong smell, as this can help narrow down what’s going on.
3. Use a fine-tooth comb if you have one and look for moving insects, white specks, or debris in the coat.
4. Pay attention to where the flaking is worst, such as the back, neck, rump, ears or belly.
5. Think about any recent changes in food, treats, grooming products, washing routine or bedding.
6. Check whether your dog is scratching, licking, rubbing or shaking more than usual.
7. Look at other pets in the home as well, since some parasites and skin issues can affect more than one animal.
Common Causes
Dry skin and coat care issues are common, especially if your dog has been bathed too often, not brushed enough, or has had a change in environment or weather.
Parasites such as lice or fleas can also cause flaking, coat damage and irritation. With lice, you may sometimes notice small moving insects or tiny pale eggs attached to the hair.
Skin allergies, mild infections, poor nutrition, and some underlying health problems can also lead to a dull coat and dandruff-like flakes.
What To Do
Keep an eye on where the flaking starts, how quickly it changes, and whether your dog is uncomfortable. Gentle grooming can help remove loose flakes and let you spot skin changes early.
Make sure bedding is clean, brush regularly if your dog tolerates it, and note any changes in food, washing products or exposure to other animals.
If you do spot parasites, avoid guessing at the cause and get proper advice on the safest next step for your dog and any other pets in the household.
When To Contact A Vet
Contact your vet if the skin is red, sore, smelly, crusty or becoming more patchy, or if your dog seems itchy, uncomfortable, or is losing hair. It’s also sensible to get advice if the problem is spreading, other pets are affected, or you’re unsure whether parasites are involved.
