Overview
If your dog’s coat has gone greasy, you should call the vet if it’s a new change that keeps coming back, is happening alongside itchy skin, bad smell, redness, scabs, hair loss or discomfort, or if your dog seems unwell. A greasy coat is often linked to grooming, skin or feeding factors, but it can also sit alongside skin disease that needs proper assessment.
Things To Check
1. Check whether the grease is all over the coat or just in one area, such as the back, tail, ears or skin folds.
2. Look closely for redness, dandruff, scabs, broken skin, hair loss, spots or a strong smell.
3. Think about whether anything has changed recently, such as shampoo, diet, treats, bedding, exercise, weather or grooming routine.
4. Check if your dog is scratching, licking, rubbing or seeming uncomfortable when you touch the coat or skin.
5. Feel for any areas that seem hot, sore, swollen or sticky compared with the rest of the coat.
6. Consider whether the coat has been washed too often, not often enough, or with a product that may not suit your dog.
7. Check for signs of ear trouble or body odour, as these can sometimes go along with skin and coat changes.
Common Causes
The most common reason is simple grooming buildup, especially if natural oils, dirt and loose hair have not been brushed out regularly.
Another common cause is skin irritation or allergy, which can make the skin oilier and leave the coat looking clumped or dirty.
Some dogs develop greasy skin and coat changes with yeast or bacterial skin problems, often with smell, itchiness or redness.
Less commonly, diet changes, breed-related skin tendencies or hormonal issues can play a part, especially if the coat change is ongoing or affects the whole body.
What To Do
Start by brushing your dog gently and regularly to remove loose hair and spread natural oils through the coat.
Use a dog-safe wash only when needed, and avoid over-washing, which can sometimes make skin problems worse.
Keep a note of when the grease appears, where it shows up and whether it comes with itch, smell or redness. That can help you and your vet spot patterns.
If the coat is only mildly greasy and your dog seems well, a few days of careful grooming and monitoring may be enough to see if it settles.
When To Contact A Vet
Contact your vet if the greasy coat is persistent, getting worse, or coming with itching, odour, redness, scabs, hair loss, sore skin or ear issues. You should also book a check if your dog seems flat, uncomfortable, is losing condition, or if the change started after a diet change or new grooming product and is not settling.
Products That May Help
If your dog’s coat is looking greasy, a sensible washing and grooming routine may help with day-to-day coat care and keep things easier to monitor.
