Can a Dog’s Diet Affect How Much They Shed?

All healthy dogs shed at times. There are many things that contribute to normal shedding, including the dog’s breed, the climate where you live, and what time of year it is. But other issues can cause shedding as well, including illness, stress, and poor nutrition.

A dog’s diet can contribute to excess shedding. High-quality dog foods made with high-quality ingredients support a dog’s whole body nutrition, including healthy skin and fur. Food made with low-quality ingredients and fillers, meanwhile, may cause your dog to lose more fur than necessary.

In the rest of this article, we’ll examine shedding: why dogs shed in the first place, what factors may cause a dog to shed more, and how the dog’s food might increase the amount of fur they lose. We’ll also take a look at some of the best dog food options to support a healthy coat.

What Causes Shedding?

All dogs shed to a certain degree; it’s part of a dog’s genetic makeup. Dogs have three different types of fur: the undercoat, which is thick and fluffy, and provides extra warmth; guard hairs, which is the stiffer, outer layer fur that protects the undercoat; and whiskers, which grow around the nose and mouth and help with the dog’s senses.

Ultimately, a dog’s different types of fur, and the sheer amount of it, work together to give them a thick coat that protects them from cold and adverse weather. Dogs have multiple hairs growing out of each hair follicle. When an individual hair gets old, it stops growing and is eventually shed from the follicle, making room for new hair to grow in. This is, essentially, what shedding is.

However, the amount that any individual dog sheds is influenced by more than just basic genetics. Dogs may shed more or less depending on what breed they are, what time of year it is, and what the overall climate is like where they live.


Certain breeds of dogs definitely shed more than others. This is because some breeds have more fur than others, or a thicker undercoat, or were traditionally bred in a climate where seasonal changes caused them to need thicker fur in winter and thinner fur in summer, or vice versa.

Dog breeds that shed heavily include:

However, this is not an all-inclusive list, and various mixed breeds may also shed heavily depending on their individual heritage.

It’s important to be aware of how much grooming and maintenance your dog will need before you adopt them. Some owners can keep shedding under control with regular brushing and bathing at home, while others may prefer to enlist the aid of a professional dog groomer.

Environmental Factors

The weather can play a huge role in your dog’s regular shedding pattern. Interestingly enough, our canine friends evolved so that their fur coats respond to both temperature and the amount of daylight they’re exposed to every day. This means that a dog will naturally have a thicker coat in the winter to keep warm; when temperatures start to warm and the hours of daylight lengthen, dogs shed a good deal of that extra fur.

It seems less intuitive to think that dogs also shed a lot again in the fall, but it’s normal. Their bodies are again responding to the changing season, and shedding their “summer coat” allows their fur to grow back thicker for colder winter temperatures.

These differences are less pronounced for dogs who live in places where the weather doesn’t change as dramatically by season. Likewise, dogs who spend most of their time indoors also generally don’t shed as much in spring and fall, because their bodies don’t have to deal with the temperature fluctuations.


Other times, excessive shedding can be caused by some sort of illness or infestation. A dog who is infested with fleas or lice may shed more due to extra scratching. Certain fungal or bacterial infections can also lead to extra shedding.

Allergies can cause shedding too. This can include food allergies, which we’ll come to in a moment, or allergies plants, things in the air, or other topical things they may come in contact with. Sometimes shedding can be a reaction to a medication the dog is taking for an unrelated concern.

More serious issues that can cause excess shedding include cancer, kidney disease, liver disease, or thyroid problems. Pregnant dogs, or dogs who are nursing puppies, may also have unusual shedding patterns.

All of these causes can be serious, so if your dog is shedding excessively, a trip to the vet should be one of your first steps. A professional can help you rule out or pinpoint medical causes of shedding, and help you figure out the next steps to take.


Sometimes, stressful situations can cause a dog to shed more. Potential stressors can include moving to a new home, changes to family makeup (new baby, death, divorce, deployment, etc.), or even anxiety over seemingly everyday situations like a visit to the veterinarian or the groomer.

If a dog is shedding because of stress, the situation may resolve itself on its own, but sometimes it may be necessary to enlist the help of your vet or a behaviorist. Behavioral therapy may alleviate the problem. In other cases, the dog may benefit from dietary supplements or even anti-anxiety medicine.


Finally, the foods your dog eats can contribute to how much they shed. Well-balanced dog food should contain all the ingredients a dog needs for a healthy life in the form of meats, vegetables, and nutritional supplements, especially omega-3 and omega-6 fatty acids.

Along with including the necessities, it’s important to make sure that the food you select does not contain any fillers. It’s common for cheaper dog brands to contain “filler” ingredients like wheat and corn, both of which can be potentially irritating to your dog’s digestive system–and which can therefore cause excess shedding.

Avoid foods that contain bone meal and animal by-products, which are legal dog food additives but add little or no nutritional value. Dog foods also absolutely do not need to contain any kind of food dyes; many common dyes are linked to allergy issues in both people and animals. Dog foods also don’t need extra sodium.

Finally, avoid dog foods that contain the preservatives Butylated hydroxyanisole (BHA), Butylated hydroxytoluene (BHT), or Propyl gallate. These preservatives are often added to dog food to stabilize the fat and oils in the food and extend shelf life, but they cause health issues and are not good for animals to actually eat.

If your pup seems to be losing more fur than you think is normal, it’s important to consider what’s normal for their breed, what’s going on in their lives, and possible health conditions.

But the food you feed your dog is important too, and feeding your dog cheap food with low-quality ingredients can definitely cause excess shedding. If you think this might be a factor, changing to a better food with no fillers and ingredients like high-quality protein and omega fatty acids may help.
