What dogs are worst for 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.

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.
