My Dog has Dandruff: Causes of Dandruff in Dogs

There are several possible causes and symptoms of dandruff in dogs. If you see flakes on your pup or on any surface where he has been resting, be sure to look for further symptoms. Contact your vet and have your dog properly inspected to rule out any underlying medical conditions.

I was giving my dog, Zorro, a massage the other day.  His black coat is shiny and smooth, but I noticed that he had many little white flakes all over his back.  At first, I thought it was dust and wondered where he would have been to get covered in dust.  I looked a little closer, brushed back his fur a little and realized that it was coming from his skin.  My dog has dandruff.  I hadn’t seen this before so I set out to learn the causes and symptoms of dandruff in dogs.

If the only symptom is dandruff, here are some questions to help narrow down the possible sources of your pup’s dandruff:

Has the weather become dryer or has the heat in your home been turned on recently?

Weather changes to dryer conditions or the furnace in your home running can cause your dog’s skin to dry out.  This would cause flaking and itching.

Has your dog eaten anything new?

Food allergies are common and can result in itchy, dry, flaky skin. If you have changed your dog’s food, treats or if he has managed to get into the garbage, he could be having an allergic reaction

Have you changed anything in your home or yard (cleaning products, plants, garden)?

Has your dog been laying on your freshly cleaned carpet or furniture?  Has he been rolling on the lawn after a treatment?  If so, his skin may be irritated.  Even the use of new laundry detergent or fabric softeners on bedding, dog coats or your own clothes can be a skin irritant.

Is your dog’s diet rich in Omega 3 and Omega 6?

These two fatty acids benefit the dog’s skin.  If your dog food is lacking in either or both of these nutrients, he may develop a skin irritation resulting in dandruff.  The best source of Omegas is directly from foods, but your vet may recommend a supplement to add to your dog’s daily routine.

How often do your bathe and groom your dog?

If you bathe your dog frequently, you may be accidentally drying his skin.  Shampoos, soaps and hair dryers can take their toll on a dog’s skin leaving it dry and flaky.

Has something changed in his daily routine or in the home?

If your dog is upset, if his little world has been disrupted in any way, he may be stressed.  Something as simple as moving his bed, or location of his dish can cause anxiety for some doggos. If his human’s work routine has changed, a new family member has arrived (human or fur), or if someone in the house is stressed or sick, your dog may be feeling anxious. Stress is a common cause of dandruff.

Does your dog have visible skin irritation?

If your dog has fleas, a recent cut or if he has food allergies, the skin can develop a fungal or a bacterial infection.  Consult a vet if your dog’s skin appears red, crusty, has bald or thinning patches of fur, or of he has an unusual odor.  All are signs of infection. These skin infections can cause dandruff.  

Has your dog’s once smooth, shiny coat become dull and coarse?

These are a couple of the symptoms of hypothyroidism.  He may be itchy and develop sores. He may begin shedding more than usual.  There are many other symptoms of hypothyroidism, including ear infections, fatigue and aversion to cold.  It is important to have this condition diagnosed and treated by a veterinarian immediately.

Does your dog have mites?

Mites can cause many types of skin irritations including itching, hair loss and dandruff.  If you suspect mites, have your dog tested and treated.  Some species of mites can be transmitted to humans and other pets. Some species of mites result in mange, another skin disease found in animals and birds.

Is your dog’s flaky skin located mainly on the face, and torso?

These areas contain sebaceous glands.  If the dandruff that your dog is experiencing is predominantly in these areas, he may have a skin condition called Seborrhea. The skin will appear red and flaky.  Your dog will also be itchy.  This is another condition where your dog might develop an odor.  Once diagnosed, a veterinarian will be able to recommend shampoos or medication to clear it up.

There are several possible causes and symptoms of dandruff in dogs.  If you see flakes on your pup or on any surface where he has been resting, be sure to look for further symptoms.  Contact your vet and have your dog properly inspected to rule out any underlying medical conditions.  Have a list prepared for the veterinarian.  The list should include all foods and treats that he has consumed, any recent changes in the home, any contact with other animals, bathing routines, soaps, shampoos, cleansers and detergents used in the home, and anything unusual behavior that you may have noticed recently. Any insight into the cause will assist with the diagnosis.
