Why is my dog’s coat greasy and itchy? | arlo.® Atlas

Read time: 3 minutes

Overview

A greasy, itchy coat in a dog usually means something is affecting the skin or the way the coat is being cared for. Common causes include an oily coat build-up, irritation from dirt or grooming products, allergies, parasites, or a skin condition that needs proper treatment. You can often check a few simple things at home to narrow down what’s going on.

Things To Check

1. Feel whether the coat is oily all over or only in one area, such as the back, ears, neck or base of the tail.

2. Look for redness, dandruff, scabs, hair loss, broken skin or a stronger smell than usual.

3. Check whether your dog is scratching, licking, rubbing or rolling more than normal.

4. Think about any recent bath, shampoo change, grooming session or new coat spray that might have left residue behind.

5. Examine for fleas, flea dirt or signs of other biting insects, especially around the tail base and belly.

6. Consider whether the problem started after wet weather, muddy walks, swimming or more time outdoors.

7. Note any changes in diet, treats, bedding or household cleaning products that could be irritating the skin.

8. Check whether the ears, paws or belly are also itchy, as that can help show whether the issue is more widespread.

Common Causes

The most common cause is simple coat build-up from natural skin oils, especially if a dog hasn’t had regular grooming or if the coat is very dense.

Another common reason is skin irritation from dirt, dampness, old shampoo, or products that haven’t been rinsed out properly. This can leave the coat looking greasy and feeling uncomfortable.

Allergies are also a frequent cause. These may be triggered by food, pollen, grass or something in the home, and itching often comes before the coat starts to look poor.

Fleas or other parasites can cause itching even when they’re hard to spot. Skin infections, yeast overgrowth and some hormone-related problems can also make the coat greasy, though these need a proper veterinary check.

What To Do

Start with a calm check of the coat and skin, then groom out loose dirt and dead hair if your dog tolerates it. If your dog has been bathed recently, make sure any shampoo was rinsed out thoroughly.

Keep bedding clean and dry, and wash anything that may be holding onto grease, dirt or allergens. If your dog is getting muddy or damp often, drying the coat well after walks can help with day-to-day comfort.

Try to avoid changing too many things at once, because that makes it harder to tell what helps. Keep a note of when the itchiness happens, where the coat looks greasy, and whether there are any other signs like redness or odour.

If the issue is mild and your dog is otherwise well, a steady grooming routine and gentle coat care may be enough to improve things. If it keeps coming back, there’s likely an underlying cause that needs sorting out.

When To Contact A Vet

Speak to your vet if the itchiness is ongoing, the skin looks red or sore, there’s a strong smell, hair loss is spreading, or your dog seems uncomfortable. These signs can point to allergies, infection or another skin problem that needs treatment.

You should also get advice sooner if your dog is scratching hard enough to damage the skin, or if the greasy coat is linked with changes in appetite, weight, energy or general wellbeing.
