Types of Dog Allergies and How to Treat Them
Have you heard someone tell you that their dog has allergies? Has your veterinarian suggested that allergies could be a problem for your dog? Do you suspect that your dog has allergies? If so, then youve probably realized that allergies in dogs are not quite as simple as we might wish. For starters, there are several different types of allergies that could be causing your dogs symptoms.
Allergies are a misguided reaction to foreign substances by the bodys immune system, which, of course, people and pets can suffer from. There are quite a few different types of allergies in dogs. Skin allergies, food allergies, and environmental allergens all pose challenges for dogs and their owners, and to make things more complicated, the symptoms of all these different types of allergies can overlap.
Symptoms of Allergies in Dogs
The symptoms of allergies in dogs may vary depending on the cause. A dog that goes into anaphylactic shock, for instance, will have a drop in blood pressure followed by shock, which is very different from a skin condition.
In general, however, the following symptoms could be a sign of an allergic reaction.
- Itchiness
- Hives
- Swelling of the face, ears, lips, eyelids, or earflaps
- Red, inflamed skin
- Diarrhea
- Vomiting
- Sneezing
- Itchy ears
- Chronic ear infections
- Itchy, runny eyes
- Constant licking
Some of these symptoms could also be a sign of another condition. Make an appointment with your veterinarian if you notice changes in their behavior to get an accurate diagnosis.
Types of Allergic Reactions in Dogs
Allergic Dermatitis in Dogs
Skin allergies in dogs, known as allergic dermatitis, is the most common type of allergic reaction in dogs. Skin allergies in dogs are mainly caused by one of three things: fleas, food allergies, and atopicor environmentalallergies.Flea allergy dermatitis is an allergic reaction to fleabites, and some dogs are allergic to flea saliva, which can cause their skin to become red, inflamed, or scabbed because their skin will feel extremely itchy. Its the easiest type of allergic dermatitis to treat, since you can apply flea medication for dogs to help heal their skin.
Another cause of skin allergy in dogs is from food allergies and sensitivities. Just like humans can be allergic to certain foods or ingredients, dogs can be allergic, which can cause itchy skin. Dogs with food allergies usually have itchy ears or paws, sometimes along with gastrointestinal symptoms. Dr. Klein, Chief Veterinary Officer for the AKC, says that food allergies are not as common as you might think. True food allergies result in an immune response, which can range in symptoms from hives, facial swelling, and itchiness to gastrointestinal signs like vomiting and diarrhea or a combination of both.
Environmental allergens can also affect the skin and be the cause of allergic dermatitis. Things like dust, pollen, fungus, and mold can cause these reactions, but in most cases, these allergies are seasonal. As with food allergies that affect the skin, the most commonly affected areas are the paws and ears (but also include the wrists, ankles, muzzle, underarms, groin, around the eyes, and in between the toes).
All skin allergies pose the risk of secondary infection. As your dog scratches, bites, and licks at his skin, he risks opening up his skin to yeast and bacterial infections that may require treatment.
Urticaria, or Hives, in Dogs
Also known as urticaria, hives on dogs are very itchy but are not life-threatening. Hives appear as a reaction anywhere from 6 to 24 hours after exposure to allergens. This consists of itchy, swelled skin, that usually looks like a red rash. Its easiest to spot hives on dogs that are hairless or have short coats. Dogs with longer hair can get them too, but its more likely that youd be able to fee the hives rather than see them. Your vet will prescribe an antihistamine in order to treat urticaria in dogs.
Edema of Face or Throat
Swelling of the throat or face looks severe, but its actually almost never fatal. This area of swelling, which can also include swelling of the eyelids or ear flaps, is known as angioneurotic edema. Its actually pretty easily treated, and despite how it looks, its a good sign in terms of allergic reactions.
If your dog has edema of any of these areas, the time for a fatal allergic reaction has most likely passed, and they arent in as much danger. Angioneurotic edema occurs anywhere from 30 minutes to a few hours after exposure to an allergen, and can also come with hives.A veterinarian will often give dogs with this reaction an antihistamine injection. Untreated, it may take a day or two for the swelling to subside.
Anaphylactic Shock
Perhaps the most alarming of all the types of allergic reactions in dogs is anaphylactic shock. Like people, dogs can go into anaphylactic shock if they have a severe reaction to an allergen. This happens when antibodies produced by the host react negatively to the allergen, dropping your dogs blood pressure rapidly and sending them into shock. This can be fatal if not treated, but luckily, anaphylactic reactions are rare in dogs.
This can be a response to any allergen, most commonly bee or wasp stings, or vaccine reactions. Because of this, your vet will always recommend keeping a close eye on your dog after theyve been given any new vaccine, drug, or food item, as they might be allergic.
If a dog has had a past incident and survived, the owner may carry an epipen, but sometimes the first occurrence can lead to death. Fortunately these reactions are very rare in dogs.
In some rare cases, a severe food allergy reaction resulting in anaphylaxis can occur, similar to severe peanut allergies in humans. The best way to diagnose and treat a food allergy is to work with your veterinarian to manage your dogs symptoms and discover the ingredient causing the reaction.
Diagnosing Allergies in Dogs
Flea allergy dermatitis is typically the easiest allergy to diagnose. It is usually diagnosed by identifying fleas on your dogs body and applying a product that kills fleas before they can bite to see if that solves the issues.
The first thing your veterinarian will do in allergy testing is rule out any other condition that could be causing your dogs symptoms. If your veterinarian feels that an allergy is a likely cause, they may propose allergy testing to try and determine the cause of the allergen that is causing the reaction. However, keep in mind it may not always be possible to determine the cause of an allergy with testing.
If you have ever undergone allergy testing, then you know that diagnosing allergies is often complicated. Its the same for dogs, but its worth it to understand what to stay away from when it comes to your dog.Food allergies are often diagnosed using an elimination diet. A food trial consists of feeding a dog one source of protein and carbohydrate for 12 weeks.
Treating Allergies in Dogs
The best way to treat an allergy is avoidance of the cause and allergen, which may not always be possible. They type of treatment depends on the type of allergy your dog has. For example, the best way to treat flea allergy dermatitis is to kill the fleas, whereas the best way to treat a food allergy or food intolerance is a change in diet.
Depending on the cause and severity of your dogs allergic reaction, your veterinarian will prescribe different things. For hives, they might suggest antihistamines, cortisones, medicated shampoos, whereas with food allergies they might suggest fish oil or other Omega-3 fatty acid supplements. For skin allergies, they might prescribe dog-safe anti-inflammatory wipes or shampoo on skin to provide irritation relief.
In addition to any lifestyle changes that might be necessary, your veterinarian may also prescribe an allergy relief medication for your dog that will help control the signs associated with the allergic reaction, such as itching and any secondary skin infections that might have developed as a result of the irritant.
If your dog has a severe allergic reaction, your best course of action is to get them to an emergency veterinary hospital as quickly as possible.
Dog Allergies
Am I allergic to my dog?
A dog is mans best friend that is, unless the man is allergic to his dog.
Pet allergies are common in the United States. According to the Asthma and Allergy Foundation of America, 15 to 30 percent of all Americans are affected. Although allergies to cats are about twice as common, allergic reactions to dogs tend to be more severe. This is especially the case in those with asthma.
Keep reading to learn about lifestyle changes and medications that can help treat dog allergies.
Dogs secrete proteins that end up in their dander (dead skin), saliva, and urine. An allergic reaction occurs when a sensitive persons immune system reacts abnormally to the usually harmless proteins. Different breeds produce different dander, so its possible to be more allergic to some dogs than others.
The allergen eventually finds its way into the animals fur. From there, it collects in carpets, on clothing, on walls, and between couch cushions. The pet hair itself is not an allergen, but the hair can hold dust and dander.
Pet dander can remain airborne for long periods of time as well. It can eventually find its way into your eyes or lungs.
The symptoms of a dog allergy may range from mild to severe. Symptoms may not appear for several days after exposure in people with low sensitivity.
Some clues you may be allergic to dogs include:
- swelling and itching in the membranes of the nose or around the eyes
- redness of the skin after being licked by a dog
- coughing, shortness of breath, or wheezing within 15 to 30 minutes of exposure to allergens
- rash on the face, neck, or chest
- a severe asthma attack (in someone with asthma)
Children with dog allergies will often develop eczema in addition to the above symptoms. Eczema is a painful inflammation of the skin.
People used to believe that exposing a newborn to the family dog could cause a child to develop a pet allergy. Thankfully for dog owners, the opposite appears to be true. Several studies in the past few years including one published in the
The only surefire way to get rid of a pet allergy is to remove the pet from your home. There are, however, ways to minimize your exposure to allergens and lessen your symptoms if you dont want to part with Fluffy.
Medications
Here are some medications and treatments that can help you manage allergies and asthma:
- Antihistamines are over-the-counter (OTC) medications such as Benadryl, Claritin, Allegra, and Clarinex OTC that can help relieve itching, sneezing, and runny nose.
- Nasal corticosteroids such as Flonase (now available over the counter) or Nasonex may reduce inflammation and control symptoms.
- Cromolyn sodium is an OTC nasal spray that may help reduce symptoms, especially if its used before they develop.
- Decongestants make it easier to breathe by shrinking swollen tissues in the nasal passage. These are available in oral form or as a nasal spray.
- Allergy shots (immunotherapy) expose you to the animal protein (allergen) thats causing the reaction and help your body become less sensitive, reducing symptoms. Shots are given by an allergist and are often used in more severe cases for long-term treatment.
- Leukotriene modifiers are prescription medications that may be recommended if you cant tolerate nasal antihistamines or corticosteroids. Due to
the risk of severe behavioral and mood changes , montelukast (Singulair) will only be used if there arent any suitable alternatives.
Natural remedies
Some people with dog allergies may find that a saline (salt water) rinse daily to clear nasal passages of allergens can help. A nasal lavage can control symptoms such as congestion and postnasal drip.
OTC saline sprays and nasal lavage kits are readily available. You can also make your own by mixing 1/8 teaspoon of table salt with distilled water.
Lifestyle changes
There are several things dog owners can do around the home to reduce allergens. They include:
- setting up dog-free zones (certain rooms, such as a bedroom, where the dog is not allowed)
- bathing the dog weekly using a pet-friendly shampoo (done by a non-allergic person)
- removing carpeting, upholstered furniture, horizontal blinds, curtains, and any other items that may attract dander
- using high-efficiency particulate air (HEPA) purifiers to reduce airborne allergens in the home
- keeping the dog outside (only in certain climates in a well-contained area and under humane conditions)
- looking into hypoallergenic dog breeds
- using a trial period when introducing a new pet to the family to assess family members reactions to the new dog
Many of the lifestyle changes and allergy medications listed above can help you to reduce uncomfortable symptoms if you love dogs and dont want to give up being around them.
An allergist can perform tests and tell you how severe your dog allergy is and what types of treatments can help. Talk to your doctor about your allergy and your treatment options.
