4 Best Dog Dandruff Shampoo Brands: Treating Your Dog’s Flakey Skin

Winter is coming to an end, and I couldn’t be happier. I’m a dog that loves being outside. Plus, because I’ve spent a lot of time in the artificial heat and dry air, I’ve developed a case of dandruff. Although I’m not embarrassed by it as some people can be, it’s not pleasant. The dry, flakey skin makes me itchy and leaves a mess for my humans to have to clean up. But just like our humans, there are shampoos that we can use to help with dandruff. And who doesn’t like a nice bath every once in a while.

What is Dandruff?

As with people, dandruff is a skin condition where small flakes of skin peel off of a dog’s body and scalp. It can be uncomfortable, messy, and a sign of more serious health conditions.It’s important to know that if your dog’s dandruff isn’t easily treated or becomes worse, they should see a vet to determine the root cause and whether or not it needs treatment.

What is Secondary Dandruff?

Secondary dandruff is dandruff associated with an underlying condition. It can only be remedied when you treat the root cause. Symptoms accompanying dandruff that may indicate a separate issue include:

  • Open sores
  • Loss of appetite
  • Sudden change in bowel movements
  • Bleeding skin 

What is Secondary Dandruff

What Can Cause Dandruff?

Dry Skin – This is the most common cause of dandruff. A dry environment – which is especially a problem in the winter when the heat’s turned on – will lead to dry skin and dandruff. While you can combat this by making sure your dog has a constant supply of fresh water or using a humidifier, dry skin resulting in dandruff is sometimes inevitable.

Allergies – Allergies – from environmental factors like pollen and grass to food ingredients such as chicken, pork, beef, or wheat – can, and often will lead to dry skin that causes dandruff.

Improper Diet – If your dog is being fed substandard food, or items that doesn’t contain the proper nutrients, it can lead to poor coat and skin health, resulting in dry skin and dandruff.

Infections – Infections, both bacterial and fungal, can quickly inhabit a dog’s body, causing dried, scaly, and itchy skin, leading to dandruff. These infections can often be an indication of a more serious underlying issue.

Parasites – Fleas are the most common parasite that can lead to dry skin and dandruff. A flea’s bite can cause an irritated, dry patch of skin that your dog will have the urge to scratch, increasing the irritation and resulting in dandruff.

Mites are another common parasite. They can cause “walking dandruff,” where the movement of the mites together with the resultant flakey skin can make it seem as if the dandruff is moving.

Cushing’s Disease – Cushing’s disease is an endocrine disorder, which leads to the improper function of hormone-secreting glands. This is one of the most serious causes of dandruff. Take your dog to the vet immediately if they’re suspected of having Cushing’s disease.

Genetics – While rare, some dogs can inherit dandruff from their parents. In this instance, dandruff would be treatable, not preventable.

What to Look for in a Dandruff Shampoo

What to Look for in a Dandruff Shampoo

There’s a dog shampoo for nearly everything, with each having its unique advantages and disadvantages. Dandruff shampoos for dogs can be broken down into three categories: certified organic, natural, and chemical-based.

Chemical-based shampoos are made of artificial ingredients and are typically the cheaper option. While not necessarily a bad choice, as they contain antiseptic ingredients that effectively combat dandruff, it’s important to be aware of what ingredients are in the shampoo, as certain chemicals may dry out the skin and make the problem worse.

Certified organic shampoos contain only natural ingredients without any added chemicals. These shampoos are great for dogs that may have sensitive skin or allergies. They must undergo a certification process to ensure they’re organic, often making them more expensive.

Natural shampoos shouldn’t be confused with certified organic brands. Companies will use all-natural ingredients, but there’s no certification process to ensure they’re 100% organic. These shampoos can have extra additives while still maintaining their natural status. Again, be aware which ingredients could irritate your dog’s allergies or sensitive skin.

Ingredients such as aloe vera, honey, peppermint, and some antiseptics are the biggest factor when buying dandruff shampoo for your dog. These ingredients will help rid your pup of dandruff as well as preventing by moisturize their skin.

Avoid ingredients such as alcohol, artificial dyes and coloring, and perfume. They can dry your dog’s skin out and make dandruff worse.
