If you go up to pet your dog and suddenly realise that their coat feels rougher than usual, and there are noticeable dry flakes, along with more fur on your clothes than what seems fair, then the coat has gone dull. If your dog went from "glossy magazine cover model" to "recently rescued from a dust storm". Then no, you are not just imagining it. Your dog’s coat has gone dull.

If you are wondering, “Why does my dog have a dull coat?” then the explanation is pretty simple. Ranging from poor grooming to allergies, insufficient diet or a recently developed skin condition, whatever the reason may be, the good news is that it can be fixed.

Why Does My Dog Have a Dull Coat?

A dog’s coat does not become dull and dry suddenly. A dull, dry and brittle coat can be a cause of some underlying issues, like:

✧ Diet gaps

A healthy, shiny coat starts with the right diet. Just like us, dogs also need an adequate amount of protein, healthy fats, vitamins and minerals to maintain a healthy coat, and if their diet is not balanced, it shows on their coat.

One of the most common causes of dull fur is the lack of omega-3 fatty acids. Lack of zinc and protein in their diet and even fruits and vegetables can alter their coat health. 
Before giving your dog an omega-3 supplement, it is important to speak to your vet first and get your dog checked out.

✧ Dehydration. 

Another very common reason why your dog’s coat is becoming dull and flaky is dehydration. When the presence of water is less in the body, the proper flow of nutrients and minerals throughout the body also becomes low, as it is water that helps carry them to the different parts of the body, in turn causing hair thinning and dry skin. It is very important to provide your dog with plenty of water at all times, particularly during the summer season.

✧ Bathing Your Dog Too Often 

Over-bathing your dog using an inappropriate shampoo is another cause of dullness and flakiness of the dog’s coat. This is because over-bathing will take away all the natural oils of the dog’s hair. The frequency with which a bath needs to be taken depends on the coat type, age, and breed of your dog.

Clearly, if your dog gets dirty in the rain, you will have to bathe him, but try not to bathe him too often.

✧ Irregular or Insufficient Grooming

Sometimes, the answer to the question "Why does my dog have a dull coat?" can be pretty simple, and it is that your dog's coat has to be brushed on a regular basis to remove dead hair and dirt from it.

Regular brushing will not only help you remove dead hair, dirt, and dander but will also ensure that the dog's natural oils are spread across the coat.

There are different brushes for different types of coats, so, in case you own a dog with medium or long hair, you need to get yourself a slicker brush for the shiny coat.

✧ Allergies and parasites

Allergies not only affect the skin but also your dog’s fur. The cause of allergies can be anything, like food or the environment, or even a flea bite can cause inflammation, in turn making a dog’s skin irritated, greasy and hair thinning. So if you have noticed your dog scratching too much, licking its paws, chewing the skin, or if red spots are forming, your doh might have allergies.

Parasites are another reason for dogs having a dull coat, as they damage tye skin and the fur.

✧ Other Underlying Health Issues

If none of the above seem to be the direct problems, then a change in your dog’s coat can be because of an underlying health issue. These can be thyroid issues, hormonal imbalances, or Cushing’s disease, which can also be the reason behind why your dog has a dull coat, especially if the change happened suddenly.

Signs of an Unhealthy Dog Coat

Before you draw a conclusion on what the cause is, there are certain signs that you should look out for:

• Fur that looks flat, brittle, or glued together instead of soft
• Excessive shedding beyond the normal seasonal blow-out
• Flaky, dry skin underneath the coat
• A coat that feels rough rather than silky
• Bald patches or thinning in specific spots
• A dull colour and having no visible shine

How to Make Dog Coat Shiny Again

Wondering how to make dog coat shiny without spending your whole paycheque at the pet store seems like an impossible and rather difficult of a task.

✧ Groom Your Dog Regularly

A consistent dog coat care routine can make a noticeable difference. Brushing helps remove dead hair, dirt, and tangles while spreading your dog's natural oils throughout their coat. Don't wait until your dog is heavily matted before reaching for the brush. A few gentle sessions each week are usually much easier for both of you.

✧ Get the Right Brushing Tools

• Using the right brushes according to a dog’s coat, breed and length of hair.
• Use a slicker brush for dogs having medium-long and curly hair and a double coat.
• Use a  rubber curry or soft bristle brush for short-haired breeds.
• Use an undercoated rake for dogs who shed heavily.

✧ Give a Balanced Diet

Dogs require a balanced diet full of healthy fats and essential nutrients like omega-3 and zinc to have a glossy, shiny and smooth coat.

• Omega-3 helps support healthy skin and coat, along with increasing sebum production.
• Protein and zinc work together to build stronger hair follicles and help keep the coat shiny. 

✧ Keep Them Hydrated

Hydration is just as important in dogs. Water helps carry essential nutrients and minerals to every cell of the body (as it is the primary fluid present in blood), promoting both the skin and overall health of a dog. It is one of the simplest dog coat health tips to follow.

✧ Do Not Over-Bathe Them

Over-bathing dogs can cause excessive hair thinning and the coat to be dry. It is especially bad when harsh shampoos are used, as these strip away the natural oils supporting skin and hair health. Washing your dog every 4-6 weeks is optimal, however it can vary depending on the breed.

Dog Dry Coat Home Remedy

If you are feeling unprepared to completely change your dog’s routine, a couple of these home remedies can come in handy:

• Use coconut oil to carefully moisturise and nourish the dry skin, giving a slight shine to their coat (do not apply excessively; your dog is not a salad).
• Try an oatmeal bath; it is an effective home remedy for a dog with a dry coat and flakiness, as oatmeal helps soothe irritated skin. 
• Use a humidifier in winter, which can keep the dog’s skin and hair healthy indoors.
• Fish oil included in the food ration is a very popular remedy for dog dry coat which once again proves the quality of omega-3 for dogs.
• You can also try bathing your dog with baking soda, as it helps get rid of dead skin cells, and help stop excessive shedding.
  

Final Thoughts

Sometimes the answer to why does my dog have a dull coat isn’t grooming them or giving them an oatmeal bath. It could also be an underlying health issue. So if your dog developed a dull coat suddenly or there is hair loss in patches and your dog has scabby or irritated skin, it is better to get your pet checked by an expert rather than solve this problem yourself. The cause could be something serious such as thyroid problems or parasites.
