Fish oil for dogs itchy skin

In this article, we will examine the best fish oil for dogs, as well as other supplements for your dog’s itchy skin and coat.

Allergies are quite common in dogs, especially if they have been on the same diet for a long time as well as not being exposed to anything new.

This means that their immune system is not stimulated and therefore can be lazy to react when something does affect them.

What are pet allergies and how do you live with them?

Allergens may also cause your pet to itch around its face or neck, where it might go red with hives, sometimes there will just appear to be patches of missing hair all over the body, and at other times you’ll notice small round scabs appearing whenever it scratches itself too much.

These  could either indicate an allergy problem or skin conditions such as eczema, however differentiating between both problems isn’t always easy, but breeds like Dalmatians, English Setters, and Labrador Retrievers are more likely to have allergies than other breeds,

Dog allergy symptoms can present themselves as:

  • Licking/scratching/chewing paws-If your dog is constantly licking his paws then he may have allergies. Dogs often lick their paws to soothe inflammation caused by allergies, or they may just be trying to help their itchy paws.
  • Red/swollen pads-If your dog’s paw pads are red and swollen, he could have allergies. Allergies lead to a buildup of fluid within the body, often causing inflammation in the paw pads or other areas of the body

  • Hair loss- If your dog is suddenly shedding large amounts of hair then he may be dealing with allergies. Hair loss can actually occur when an allergic reaction causes the body to release histamine, which in turn causes blood vessels around the skin to dilate.
  • Swollen/itchy face- If your dog’s face appears swollen and/or itchy then he may be dealing with allergies. Allergens can cause dogs to develop a runny nose or watery eyes, which leads to the swelling and itchiness that you might notice on his face.

  • Lethargy/depression -If your dog is acting sluggish and sad then he may have allergies. Allergies can cause dogs to feel tired and listless due to the inflammation that they cause throughout the body.
  • Runny nose -If your dog’s nasal passages are extremely congested then he could have allergies. The build-up of fluid caused by allergies can lead to a runny nose, which your pup may snort and sneeze through.
  • Watery eyes -If your dog’s eyes appear watery and bloodshot then he could be dealing with allergies. Allergens often cause dogs to develop eye infections or inflammation, which leads to watery eyes.

  • Vomiting/diarrhea -If your pup is frequently vomiting or experiencing diarrhea then he may have allergies. Allergens are known to cause dogs to feel nauseous, which can lead them to throw up or have diarrhea.
  • Abdominal discomfort -If your dog is crying out in pain then he could be experiencing allergic reactions. When dogs are dealing with allergies they often feel abdominal discomfort, resulting in whining and howling.
  • Skin sores -If your dog develops frequent skin sores then he might have allergies. Allergies often cause dogs to develop cold sores around their paws, which can lead to open wounds that ooze and crust over as they heal.

4 main causes of allergies

  1.  Fleas
  2. Allergies to something they inhale (known as ATOPY)
  3.  Food allergies
  4.  Allergies to something they are in contact with

1) Fleas

A flea bite causes an allergy! This usually takes the form of a lot of itching on one region of the body, particularly the rear.

When a flea bites a dog, he or she will undoubtedly be itchy.

A dog that does not have an allergy will just itch and bite the area where he has been bitten, but a dog with a “full-blown” allergy to the flea bite will be continuously itching over a larger surface area.

This part may become somewhat red and inflamed, resulting in secondary infection, so always visit your veterinarian for advice.


Your veterinarian will advise you on the best treatment for your pet’s itching and inflammation, which may include a topical, oral, or injected medication. An antibiotic or antifungal drug might be prescribed if your dog or cat has an infection.

2) Atopy (an allergen that has been inhaled)

Atopic dermatitis is an inherited disease that causes allergic reactions after repeated exposure to an “allergen.” Plant pollens, house dust mites, or mold spores are some of the allergens. Between the ages of one and three years, most dogs begin to show signs of allergy.

Dogs usually display symptoms on their skin, such as itchyness and licking. They frequently lick and scratch between their toes. They can also develop a lot of itching around their eyes and become red in complexion.


Food allergies can be treated, while airborne allergies cannot. However, most cases of atopic dermatitis may be controlled with medication. Cortisone-type medicines (steroids) are usually used for the treatment of atopic dermatitis.

They’re an excellent anti-inflammatory and anti-itch therapy that’s also effective against itching. Steroids, on the other hand, have more adverse effects (such as excessive drinking, urinating, and eating) than other therapies.

Hyposensitisation therapy and immunomodular medications are additional possibilities that your veterinarian might discuss with you.

3) Food allergies

Food allergies can affect dogs of any age and are most often induced by eating the same food for an extended period of time (i.e, NOT a “new” food).

 Symptoms of food allergies can vary, but typically result in one or more of the following: 

  • itching all over the body itching in specific areas (eg face)
  • vomiting, 
  • diarrhea 
  • passing blood or mucus regularly

When a dog is allergic to something in their food, it tends to be either a protein, such as chicken. Beef, lamb, etc. or a carbohydrate( soy or rice).

Food allergies can affect dogs of any age and are most often induced by eating the same food for an extended period of time

By an “elimination diet,” which entails completely stopping what your dog normally eats and then starting them on a new diet that includes a different protein source, (eg, swap chicken for duck), and/or carbohydrate source (substitute the soy, rice, etc), we can determine if they have food allergies.

4) Contact allergy

This is substance that your dog will come into contact with.

If your dog is allergic to grass, you’ll notice skin irritation, redness, and itching on the spot they’ve come into touch with

Typical irritants include:

plants, gardening supplies and chemicals (mulch, cedar chips, fertilizer, pesticides, etc.), fabrics, leather, rugs or carpets, Plastics, rubber, Soaps or shampoo & Household cleaners, Deodorizers, Medications for bacterial, fungal or parasitic infections, as well as insect bites and food allergies.


Depending on his requirements, an antihistamine or a steroid may be used.  A cream or ointment may be given to you to use on the afflicted regions.

If a secondary infection arises, your dog will require antibiotics. It’s also feasible that she’ll give you instructions for washing your dog with shampoo twice a week.

What can you do about it?

Allergic reactions like hotspots, dry skin, acne, and more can greatly affect our dogs and are usually a sign of food allergies or environmental factors. Sometimes dogs need additional dietary supplementation.

An inadequate diet, illness, age, certain diseases, and veterinary recommendations are all reasons why dogs may benefit from a nutritional boost.

Which supplements can help your dog with allergies?

When your pet’s immune system responds to an irritant, allergies can occur in a variety of ways.

These might be due to different pollens in the air, saliva from fleas, particular proteins or carbohydrates found in meals, or even something your dog has come into touch with such as your laundry detergent or carpet cleaner.

Anti-inflammatory drugs are often the first line of treatment for dogs that have allergies as these can help if your pet has itchy skin.

However, there are also supplement options available that may be effective too, such as fish oil.

I’m a former veterinary technician who has researched the best allergy support supplement for dogs, so you don’t have to. And now I’ve taken an in-depth look at the best fish oils on the market to help you determine if they are suitable for your dog.

Is fish oil good for dogs every day?

Adding fish oil to your dog’s diet is one of the best things you can do. Besides supporting your dog’s heart health, fish oil promotes a silky coat, reduces itchy and flaky skin, and relieves allergies and joint pain. As well as strengthening their immune system, it may also be able to help them fight cancer.

Can I give human fish oil to my dog?

Dogs can benefit from fish oil and omega-3, but it’s best to avoid giving them supplements designed for humans. It’s really unnecessary to give your pet something that’s meant for humans when there are so many omega-3 fatty acid supplements specifically for dogs on the market.

Is Omega fish oil good for dogs?

Omega-3 fatty acids have a number of potential benefits in dogs and cats with allergic skin, such as reducing inflammation and improving the skin’s general condition. When the skin is healthy, its natural barrier function against allergens (pollens, dust mites, molds) improves, minimizing the allergic reaction.

What are the benefits of fish oil for dogs?

  • Decreasing Inflammation: One of the key functions of the omega-3 fatty acid EPA is supporting the body’s natural anti-inflammatory response. Dogs and cats can suffer from numerous inflammatory conditions that can affect their health and well-being. Studies have shown supplementation of omega-3 fatty acids from fish supports dogs and cats with inflammatory conditions associated with the skin, joints, kidneys, and heart.
  • EPA promotes healthy triglyceride (fat) levels within the blood of dogs
  • Shiny Coat and better skin condition. Essential fatty acid supplementation is known to maintain general skin and coat quality in dogs and cats. Human studies have also shown that omega-3 fatty acid supplementation supports weight loss.
