What do you feed a dog with allergies
Dog Allergies: What You Need to Know
Allergies are quite common in dogs of all breeds and backgrounds. They occur when a dogs immune system has a hyper-reaction to a foreign substance, such as pollen, flea saliva, vaccines, spider bites, bee stings, or even certain foods that normally would cause little or no reaction in most dogs.
We suspect certain dog allergies, such as atopy or allergies to pollens and plants, are primarily hereditary in basis. Most of these dogs begin to show allergic signs between 1-3 years of age, often after they have previously been exposed to the underlying cause. While most allergies cant be cured, the goal is to manage them with treatments that can help relieve or control a dogs allergic symptoms.
Signs That Your Pet Might Have Dog Allergies
The signs of allergies vary depending on the type of allergic reaction a dog is experiencing and can vary from dog to dog. Most allergic signs in are dermatologic, which can range from itching and inflammation of the skin, feet and ears, to hives and possibly swelling of the face. Some allergic dogs can have clear watery eyes and nose, as well as sneezing.
Gastrointestinal signs can also occur such as vomiting and/or diarrhea with or without blood. In rarer cases, a much more severe and different allergic reaction called an anaphylactic reaction can occur. This is an immediate type of hypersensitivity and leads to a potentially life-threatening situation where a dog can acutely collapse due to shock and a severe drop in blood pressure.
Types Of Allergies Your Dog Might Have
There are several common types of allergies in dogs, including:
- Fleas: Reaction to the protein in flea saliva, not the actual fleas. Therefore, a dog with only one flea can still have an extensive systemic allergic reaction due to their bodys reaction to just that one fleas saliva.
- Canine Atopic Dermatitis: Also known as atopy or atopic dermatitis (AD), this is a very common canine allergy. This is usually an inherited predisposition to develop allergic symptoms after exposure to relatively common substances or allergens in the air such as pollens, grasses, weeds, molds, or fungi. Common signs of atopy are itching and inflammation in a dog often seen in the underarms, groin, face and feet. Atopy is often seasonal.
- Food Allergies: Allergies to food can manifest with a chronic skin condition such as flaky, itching skin, chronic licking or biting of the paws, or chronic ear infections (often with secondary opportunistic bacterial or yeast infections). Dogs can develop allergies to a food or substance over a period of time, even if they may have had no previous issues with that food substance or protein.
- Contact Allergies: Contact allergies are found when a dog has direct contact with a caustic surface or chemical, causing severe irritation to the skin. Household cleaners, carpet cleaners, fertilizers, topical medication, and essential oils may all potentially cause a contact allergy.
- Bacterial Hypersensitivity: Bacterial hypersensitivity occurs when a dogs immune system overreacts to the normal bacterial flora on their skin. This often occurs when other health conditions are present, such as hypothyroidism, inhalant allergy, and/or flea allergy.
Diagnosis And Treatment of Your Dogs Allergies
The best method of controlling allergies is to know what the allergen is and to avoid it or control it. Your veterinarian can perform an extensive examination with history to try to help determine the most likely cause and formulate a practical treatment plan. The gold standard for diagnosing allergies in dogs is immunotherapy or allergy testing to determine the actual cause of the allergic response and to tailor an allergen-specific immunotherapy (ASIT).
There are several options for treating your dogs allergies, including:
- Flea Prevention: Flea prevention is obvious, relatively easy, and will help dogs who suffer from allergies to fleas. Flea eradication through an extensive anti-parasitic protocol may be necessary to improve the allergy sufferer.
- Antihistamines: This treatment is generally inexpensive and safe with few side effects, but different types can have variable effects and dont work on all dogs.
- Medications: Cortisone products have been commonly used in the past with good effects on allergy sufferers, but these types of medications are not without side effects, so they need to be used judiciously and only for shorter periods of time. Newer medications such as cyclosporines (Atopica), Apoquel (an immunomodulatory), and Cytopoint (an immunotherapeutic) are currently being used extensively by clinicians with good results to minimalize the severe itching response the dog gets from allergies.
- Dietary Changes/Hypoallergenic Diets: Dairy, beef, and wheat can be responsible for up to 80% of food allergies in dogs. Hypoallergenic diets utilize one novel protein (or only one new protein in a diet) as the protein source. Most pets with food allergies respond well when switched to a store-bought hypoallergenic diet, but occasionally an animal suffers from such extreme allergies that a homemade diet is the only option. In this case, the diet should be customized with the aid of a veterinarian, veterinary dermatologist, or veterinary nutritionist.
- Environmental and External Aids: Air purifiers can help reduce certain molds. Dust and pollens are best controlled by using an air cleaner with a high-efficiency particulate air (HEPA) filter. Air conditioning can also reduce circulating amounts of airborne allergens because windows are then kept closed.
- Medicated Baths and Supplements: Many medicated dog shampoos have compounds in them that are aimed at soothing the injured skin and skin barrier and calming inflammation. In addition, frequent bathing (weekly to every other week) can remove allergens from the coat, which may contribute to skin allergy flare-ups. These shampoos are often prescribed by your veterinarian, and directions for use should always be read completely and followed explicitly.
- Supplements: Omega-3 and Omega-6 essential fatty acid supplements can be considered by your veterinarian. These fatty acids are naturally anti-inflammatory and anti-oxidative agents.
- Antibiotics and Antifungal Medications: Antibiotics are frequently needed to treat secondary skin infections. Anti-fungal medications are frequently needed to treat secondary yeast infections.
Each possible allergy treatment has its advantages and drawbacks. Finding the source of your dogs allergy and discussing a specific treatment plan with your veterinarian is recommended.

- Treatment for dog allergies depends on what your dog is allergic to.
Types of Allergies in Dogs
Here are a few of the different types of allergies a dog can have.
Flea Allergies
An allergy to fleasis the most common skin disease seen in dogs. The bite of just one or two fleas per week is enough to make affected dogs itch. Flea saliva is believed to be the allergen that causes the itchiness.
Seasonal/Environmental Allergies
Also known as atopy,seasonal or environmental allergiesare caused by substances that exist in your home, backyard, and anywhere else your dog spends time.
These allergens can be inhaled, as with pollen, or absorbed through the skin when your dog touches them. Common triggers (allergens) for these allergic reactions include pollens, plant or animal fibers, dust mites, and mold spores.
Food Allergies
These are also known as adverse food reactions. Dogs can develop an allergy to a particular food at any point during their life, regardless of whether they have eaten these brands or types of foods in the past.
The most common food allergy for dogs is to a protein source in the diet, but sometimes the allergy is to grains and/or other ingredients.
Dog Allergies Signs
Dog allergies signs can include:
The type and severity of these signs depend partly on the type of allergy your dog has.
Signs of Flea Allergy Dermatitis in Dogs
The most common symptom of flea allergy dermatitis is itchy skin and irritation at the base of the tail, although other areas of the body may also be affected.
Seasonal/Environmental Allergy Signs in Dogs
Common symptoms include scratching/itchy skin, licking (especially the paws), and face rubbing. Affected dogs may also experience red skin, loss of fur, and recurrent skin and/or ear infections. You may see red skin or fur loss on your dogs paws and lower legs, face, ears, armpits, and belly.
Signs of Food Allergies in Dogs
The symptoms of food allergies are often the same as for seasonal/environmental allergies. There may also be GI signs, such as diarrhea, vomiting, or an increased number of bowel movements per day.
Is There an Allergy Test for Dogs?
Yes, but allergy testing in dogs is done for seasonal/environmental allergies only. Studies have shown thatblood testing and skin testing for food allergiesare not accurate in dogs. Studies have also shown that hair and saliva testing for seasonal or environmental allergies in dogs are not accurate.
Prior to performing allergy testing, your veterinarian should rule out other causes for your dogs allergy symptoms. Allergy testing should not be used to confirm that your pet has seasonal/environmental allergies, but to determine the specific things to which your dog is allergic.
Seasonal/environmental allergy testing can be performed in dogs by either skin testing or blood testing. Skin testing is the most accurate type of allergy test, and its generally performed by board-certified veterinary dermatologists.
Allergy testing should not be used to confirm that your pet has seasonal/environmental allergies, but to determine the specific things to which your dog is allergic.
For skin testing, mild sedation is required. The fur is clipped in a small area, and a series of very small amounts of allergens are injected into your dogs skin. The degree of the allergic reaction to each allergen determines whether your dog is allergic to it. The cost of these tests can range from $300$700.
Dog Allergy Treatment by Type
Treatment will depend on what the vet determines your dog is allergic to. Here are a few examples of how your vet might approach treating allergies.
Treatment for Flea Allergies
Treatment for flea allergy dermatitis is aimed at reducing the symptoms of itchy skin and irritation until the fleas are eliminated. To eliminate allergy symptoms in a flea-allergic dog, strict flea control is required.
There are many highly effective flea control products and medications available. Some are topical and come in the form of a liquid that you squeeze onto your dogs skin, such as Advantage, Revolution, or Vectra. Others are given orally in the form of chews, such as Simparica, NexGard, or Comfortis. Consult with your veterinarian to determine your best option.Oral preventions tend to be more effective than topical, but use cautionsome of the oral preventions have flavorings your dog might be allergic to.
In severe cases, a dogs environment must be treated for fleas as well. Vacuum thoroughly to remove eggs, larvae, and pupae, and discard the vacuum bag. You can use insecticides inside and outside your home to treat allflea life stages.
It is important to use an insecticide containing an insect growth regulator, such as methoprene or pyriproxyfen, to halt the development of flea eggs and larvae. You can hire a professional exterminator, but you should specify that the treatment is for fleas.
Treatment for Food Allergies
The treatment for food allergies in dogs is to feed a hypoallergenic diet for at least 12 weeks. This is the only way to determine if your dog has a food allergy.
Hypoallergenic diets either have limited ingredients with an uncommon protein source or are processed in a special way (hydrolyzed) to be less likely to cause allergic reactions. The concept is that a dog cannot be allergic to a food that they have not been exposed to before.
Consult your veterinarian to choose the proper diet. Over-the-counter foods are not recommended for a proper food trial. Treats, flavored medications, and human foods will also have to be eliminated during this trial period.
Other allergy treatment for dogs are aimed at reducing the symptoms while waiting to see if the diet change is helpful. Cytopoint, Apoquel, or steroids may be used to help control itching while waiting to see if a hypoallergenic food trial results in improvement of your dogs allergy symptoms.
Treatment for Seasonal/Environmental Allergies
If allergy testing has not been performed, then the treatment is symptomatic, meaning that it aims to reduce or eliminate your dogs symptoms. Treatments can include:
Oral medications, such as Apoquel, Atopica, or antihistamines
Injectable medications, such as Cytopoint
Fatty acids
Steroids
Frequent bathing and other topical therapies, such as sprays, wipes, or a mousse
Steroids should not be used long-term in the management of allergies due to the risk of significant side effects.
If an allergy test has been performed, then the ideal allergy treatment for dogs is avoidance of the allergen. This is possible in a few, select circumstances, but most dogs are allergic to a variety of substances that can be difficult to avoid completely.
Most dogs are allergic to a variety of substances that can be difficult to avoid completely.
Other treatment can include an allergy vaccine, also known as immunotherapy, which is given either by injection under the skin (allergy shots) or by mouth. The goal of immunotherapy is to make the immune system less reactive to the allergy-causing substances.
The success rate of immunotherapy is 6070%. This is the best long-term approach to allergy control, especially in younger pets that experience symptoms most of the year. Symptomatic treatment can and should be given while starting immunotherapy. It may be many months before any improvement in symptoms is seen from immunotherapy alone.
