How Do You Know If Your Dog Has Food Allergies

How Can You Tell If Your Dog Has Skin Allergies

How To Find Out If Your Dog Has Food Allergies | Hair Testing

Your pet may become itchier than normal and may bite, lick, chew, rub or nibble at their: As the disease progresses they may develop skin infections which may make the skin smell, feel greasy or you may notice a rash. Some animals will be worse in the summer if they are allergic to a particular grass or pollen and may suffer with hay fever .

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

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.

Other treatment can include an allergy vaccine, also known as immunotherapy, which is given either by injection under the skin 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 60-70%. 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.

Rule Out Other Health Issues

Your veterinarian will take a full history on your pet and do a general exam.

Next, they will likely run tests to rule out conditions with similar symptoms like mange, ringworm, yeast infections, bacterial infections, flea infestations, and environmental allergies.

Ruling out those conditions comes first because true food allergies are relatively uncommon.

If there is no other apparent cause for your dogs symptoms, your veterinarian may begin to suspect that food allergies are behind your dogs itchy skin or ear infections.

Even if your vet finds a reason for your dogs skin problems, they may still suspect that an adverse food reaction is at least partially responsible since, for example, yeast infections can develop as a result of food allergies.

Once a diagnosis of food allergies seems to be a reasonable possibility, your vet will recommend a food trial.

Itchy Skin Red Underbelly And Dull Coat

Together, these signs can indicate an allergy. Your dog itches constantly without relief, possibly causing hair loss in the affected patches.

What It Looks Like: Skin underneath the hair is red or pink, dry, and inflamed. No relief with baths, conditioners, or over-the-counter allergy medications. Excessive, near-constant scratching.

What It Means: Environmental allergies or food allergies.

But First! Rule Out

Shampoo residue on your dogs skin is a leading cause of contact dermatitis, and often resolves by switching to a milder shampoo and rinsing thoroughly. Try this trick: Shampoo your dog, and rinse him until you think you are done. Then, rinse two more times to be safe!

Shampoos containing artificial colors , sodium laurates, phthalates, mineral oil, and fragrances can all cause irritation. Try switching to a species-appropriate, all natural rinse for your dog, such as ones that contain apple cider vinegar or coconut oils.

In Dogs With A Dog Food Allergy How Long After Eating Do Symptoms Appear

How do you know if your Dog has Allergies?

Symptoms caused by a food allergy in dogs can appear in as little as a few minutes or as long as 24 hours. Hives, in particular, can emerge around 6 to 24 hours after your dog eats something theyre allergic to.

Also known as urticaria, hives are itchy red bumps. Theyre easier to see on dogs with short-haired coats. If your pooch has long hair, you might need to feel their skin to spot them.

Diagnosis Of Dog Food Allergies

Many dog food allergies are genetic, but the genetic reaction can manifest very early in puppyhood or after years of sensitization to that food. The early weeks of puppyhood can also trigger food allergies. A dogs immune system at that age is adapting to, and interpreting its environment. We dont yet fully understand what can happen at that point that predisposes some dogs to allergies.

First, have your veterinarian rule out other medical conditions. At that point, your veterinarian would place your dog on an elimination trial, the most accurate way to determine food allergies. An elimination trial means that your dog will go off of all the diets and treats they have been eating previously, and begin with a new diet suggested by your veterinarian.

Your dog would be on this hypoallergenic elimination diet until they have improved, approximately 8-12 weeks. You would then do a diet challenge by reintroducing one food that your dog had been eating before. If there is a reaction within 7 days , it confirms food allergy. If there is no reaction, you may need to look for another explanation for the improvementseason change, elimination of parasites, resolution of infection.

This can be a lengthy process, but there is no other test that will reliably identify food allergy. Skin testing, blood tests, saliva tests and hair tests all are wildly overstated but do not prove or disprove allergy to certain foods.

Dog Food Allergy Treatment

Dog food allergy treatment boils down to one underlying principle: identify foods your dog is allergic to and avoid feeding him those. “That’s why the elimination diet and trial period is so essential,” says Shmalberg, “as it’s the only way to identify which foods, and food proteins, a dog can tolerate and which he can’t.” Now, if it’s a food intolerance rather than an allergy , a food trial is still helpful, but a simple change of diet can be just as effective. “A diet with a different composition from the one currently being fed is often enough to improve symptoms,” Shmalberg explains.

Unless formulated well, with the advice of a veterinary nutritionist, many homemade diets are deficient in certain critical nutrients.

Aside from that, there are a few other tactics that come up in dealing with food allergies and intolerances. Here’s a brief overview, plus considerations, pros, and cons for each.

Antihistamines and Other Medications

Homemade Dog Food Diets

Homemade diets are sometimes used for elimination diet food trials, and for dogs with food intolerances or allergies. It’s easy to see why they’re effectivethe owner has total control over the ingredients. But there’s an issue with homemade dog food diets. “Unless formulated well, with the advice of a veterinary nutritionist, many are deficient in certain critical nutrients,” says Shmalberg, “and those deficiencies could cause issues in the long run.” The preparation is labor-intensive for the owner, too.

    Most Common Causes Of Food Allergy In Dogs

  • Beef. Proteins are common food allergens. Feeding your dog a single food for years increases their potential to develop an intolerance or allergy to one or more ingredients. Beef is one of the most common ingredients in a lot of pet foods, which may be the reason its the most common food allergen. I feed our three dogs a raw diet and we rotate meats every week. I do this partly to ensure we decrease the risk of developing a food allergy.
  • Dairy. Some dogs have problems digesting lactose. This is an intolerance, rather than an actual allergy. Lactose intolerance leads to gas, diarrhea, or vomiting. Whats tricky is that a true dairy allergy can lead to these symptoms too, so its hard to know if a dog is suffering from an allergy or an intolerance. One important distinction: a dairy allergy may manifest as skin itchiness or related symptoms, whereas lactose intolerance is always about digestion.
  • Wheat. There are many misconceptions regarding carbohydrate-containing foods for dogs, especially grains. Its much more common for dogs to have allergies to meat than grains, for instance. However, some dogs do have an allergic reaction to wheat. Check with your vet or pet nutritionist about grains, as every animal should be treated as an individual.
  • Eggs. An egg allergy means that your dogs immune system overreacts to the proteins present in the egg yolk. Fortunately, its relatively easy to avoid eggs. Just be sure to double-check food labels.

    4 Signs Your Pup May Have Allergies

    In addition to novel foods, i.e. choosing new protein and carbohydrate sources for your dog in an elimination diet, you can also feed them a hydrolyzed diet. A hydrolyzed diet is one made with intact proteins that have been broken down into such small molecules that your dogs immune system cannot recognize them as allergens. Starch or rice also make great sources of carbohydrates for your dogs diet because they rarely cause allergic reactions. Prescription foods and those approved by your veterinarian are preferable to those available over-the-counter.

    Allergy Symptoms In Dogs

    If your dog is experiencing symptoms like itchy ears and skin or stomach issues, theres a good chance your dog may have a food allergy.

    Allergies in dogs are usually genetic. When this issue is triggered, its because the dog came into contact with whatever it is he or she is allergic to. Environment can affect your dogs allergies but a genetic predisposition is almost always the root cause.

    According to pets webmd, 10% of all allergy cases in dogs are food allergies. Studies are still being conducted to determine just what causes some dogs to express the trait of food allergies.

    It’s Crucial To Act Fast

    Noticing if your animal has discomfort, itching, redness and irritation in certain areas can make all the difference between a fast treatment and one that’s more long and painful. Dogs often scratch constantly and strongly, increasing the chances of wounds becoming infected and thus aggravating the whole situation. So, if after a few days you notice that this situation persists, consult the veterinarian.

    Common Food Allergens For Dogs

    ð?¶ How To KNOW If Your DOG Has ALLERGIES â?ï¸? (Types, Breeds and Causes)

    In general, the protein sources in many dog foods are some of the most well-known offenders. Beef products can be especially triggering for dog food allergy sufferers. While this may seem counterintuitive since dogs are primarily carnivores, if the quality of meat isnt up to par its likely to cause upset.

    Many pet owners also mistakenly assume that their dogs have iron stomachs and can put down almost anything. In truth, most dogs are lactose intolerant and the dairy products found in many common dog food brands can seriously disrupt their systems. Be careful if you are in need of a puppy milk replacer for nursing newborn pups.

    In addition to beef and milk products, some other notable food allergens include:

    • Chicken
    • Wheat
    • Soy

    Just like humans, dogs can also have a severe gluten intolerance. Wheaten Terriers and Irish Setters are notorious for developing celiac in their lifetimes. This results in internal intestinal inflammation that can prevent the digestive system from properly absorbing nutrients. Outwardly this might result in poor coat conditions, rapid weight loss or persistent diarrhea. To remedy this, dogs must be strictly fed grain-free dog food. Feed and treats must be entirely devoid of wheat-derived products like rye, oats, barley.

    Lastly, allergies in dogs can be traced back to food, environment, or both.

    • Not a substitute for professional veterinary help.

    When I was a practicing veterinary technician, I encountered many clients with questions about their pets potential allergies. Theyd be surprised to find out that dogs can develop allergies to certain ingredients even in premium foods. Increasingly, its easy to find pet foods made with high-quality ingredients and limited fillers. Yet our dogs can still be allergic or intolerant to a number of these ingredients.

    First off, its important to know theres a big difference between a food intolerance and a true food allergy for dogs. A dog food intolerance is when a dog has difficulty digesting a certain ingredient, like dairy, whereas a food allergy triggers an immune response.

    Jean Hofve, DVM explains in Whole Dog Journal that for most dogs, skin and gastrointestinal problems are not usually the result of a food allergy, but rather due to environmental allergies like pollen or grass. However, some dogs are truly food-allergic.

    Read on to find out what that means, and how youll know if your dogs food is causing an allergic reaction.
