Dog Food Intolerance Symptoms

August 22, 2024

Pet owners often mix up dog food allergies with intolerances, but they are actually two different issues your pet can face.

Allergies involve the immune system overreacting to a specific ingredient in food, whereas food intolerance is a digestive issue where a dog’s system struggles to process certain foods or brands.

Common dog food intolerance symptoms include vomiting, diarrhoea, excessive gas, skin irritations, and behavioural changes.

Therefore, to take better care of your pets, it is important to check if your dogs have any sensitivities so you can adjust their diet and lifestyle.

Understanding Dog Food Intolerance

Dog food intolerance occurs when a dog's digestive system cannot properly process certain ingredients in their food.

This can lead to a range of symptoms, including gastrointestinal issues, skin problems, and even behavioural changes.

Unlike dog food allergies, which trigger an immune response, food intolerance is a purely digestive issue.

This means that while your dog might not experience an allergic reaction, they can still suffer from significant discomfort due to their body's inability to break down certain foods.

The underlying cause of intolerance is often linked to specific proteins (like beef or chicken), carbohydrates, or additives in dog food.

For example, some dogs may struggle to digest beef, dairy, wheat, or soy, while others might react poorly to preservatives or artificial additives.

Common Symptoms of Dog Food Intolerance

Recognising the symptoms can be tricky since they often develop gradually and can mimic other conditions like allergies.

Here are some common symptoms that might indicate your dog is experiencing food intolerance.

1. Gastrointestinal Issues

One of the most noticeable signs of food intolerance in dogs is gastrointestinal distress. This can include vomiting, diarrhoea, excessive gas (flatulence), and bloating.

For example, if your dog frequently has an upset stomach after meals or you notice loose stools more often than not, these could be signs that something in their diet is not agreeing with them.

These symptoms may not always be severe, but they are worth paying attention to.

They might seem small, but if not addressed quickly, they can cause your dog discomfort and lead to bigger problems later.

2. Skin Problems

Skin issues are another common symptom of food intolerance in dogs.

Dogs with food intolerance may develop itchy, red, or inflamed skin. You might also notice rashes, hives, or persistent scratching.

These reactions can result from their body struggling to process certain ingredients in their diet.

Dogs with food intolerance often suffer from chronic skin conditions that do not respond well to typical treatments.

These skin problems can lead to discomfort, irritation, and even secondary infections if not addressed.

3. Behavioral Changes

Food intolerance can also lead to changes in your dog’s behaviour. Dogs in discomfort may become more irritable, lethargic, or withdrawn.

They may also show less interest in food or become picky eaters.

Dogs can not verbally tell us when something is wrong, so changes in behaviour are often the first clue that they are not feeling well.

4. Frequent Ear Infections

If your dog often scratches its ears or shakes its head, or if you find persistent foul odour coming from its ears, it might be more than just a simple infection.

Food intolerance can cause inflammation that leads to recurring ear problems.

While ear infections can be treated with medications, they may continue to recur if the root cause—in this case, food intolerance—is not addressed.

Causes of Dog Food Intolerance

Understanding what causes dog food intolerance can help you avoid potential triggers and manage symptoms more effectively.

The most common culprits behind food intolerance include proteins, dairy products, grains, and additives or preservatives.

Proteins

Proteins such as beef, chicken, and lamb are frequent triggers of food intolerance, as some dogs may struggle to digest these proteins.

This inability to ingest meat proteins can lead to gastrointestinal distress and other symptoms.

It is worth noting that while chicken is a common protein in many dog foods, some dogs might develop an intolerance to it over time.

Dairy Products

Dairy is another common trigger.

Many dogs are lactose intolerant, which means their digestive systems cannot break down lactose (the sugar found in milk and other dairy products).

This can lead to symptoms like diarrhoea, gas, and stomach pain.

Grains and Carbohydrates

Wheat, soy, and corn are often used as fillers in commercial dog foods.

While not all dogs have issues with these ingredients, some may develop an intolerance, leading to digestive problems or skin reactions.

Additives and Preservatives

Artificial additives, preservatives, and colourings in dog food can also trigger intolerance. These substances can be hard for a dog’s digestive system to process and lead to other symptoms down the line.

Choosing foods with natural ingredients and minimal additives can help reduce the risk of food intolerance.

Diagnosis of Food Intolerance in Dogs

Accurately diagnosing food intolerance requires a combination of careful observation, dietary adjustments, and professional guidance.

With the right approach, you can identify the bad ingredient that is upsetting your canine and take steps to eliminate it from your dog’s diet.

Here are a few ways to diagnose dog food intolerance.

Elimination Diet

An elimination diet is one of the most effective ways to identify food intolerance.

This involves removing potential trigger ingredients from your dog’s diet and then gradually reintroducing them one by one.

By monitoring your dog’s reactions to each ingredient, you can pinpoint the cause of their symptoms.

Food Diary

Keeping a detailed food diary can be invaluable when diagnosing food intolerance. Record everything your dog eats and any symptoms it experiences.

This can help you and your vet identify patterns and determine which foods are causing issues.

At-Home Sensitivity Tests

You can also try at-home sensitivity tests to determine what is bothering your dog.

These tests typically involve taking a sample (such as saliva or hair) from your dog and sending it to a lab for analysis.

The results can help you tailor your dog’s diet and lifestyle to suit their needs better.

Veterinary Consultation

Working closely with a veterinarian is crucial during this process. A vet can provide guidance on how to conduct an elimination diet safely and effectively.

They will check your dogs for any other health issues that might be causing problems.

Blood tests can help rule out other factors, and while allergy tests are not always necessary, they might be helpful.

Dog Food Intolerance Treatment and Management

Once you have identified the food causing your dog’s intolerance, the next step is to manage and treat the condition.

Here are ways to help your dog feel better and prevent future issues.

1. Remove the Offending Food

The first step is to eliminate the bad food entirely from their diet. This means no treats, table scraps, or other food items containing the offending ingredient.

2. Alternative Diets

Consider switching your dog to a hypoallergenic or limited-ingredient diet. These diets are specifically formulated to reduce the risk of food intolerance by using simple, easily digestible ingredients.

3. Dietary Supplements

In some cases, dietary supplements that support digestion can be beneficial. Probiotics, digestive enzymes, and other supplements can help your dog’s digestive system process food more effectively.

4. Regular Vet Check-Ups

Regular check-ups with your veterinarian will help ensure that your dog’s condition is under control and that their diet meets their nutritional needs. Your vet can also make adjustments to your dog’s diet as needed.

Preventing Dog Food Intolerance

Prevention is always better than cure, and this certainly applies to food intolerance in dogs.

While you can not always prevent food intolerance, there are steps you can take to reduce the risk.

1. Introduce New Foods Gradually

When adding new foods to your dog’s diet, do so gradually. This will allow you to monitor for adverse reactions and ensure that your dog’s digestive system has time to adjust to new formulas or mixes.

2. Feed a High-Quality Diet

Choose a high-quality, balanced diet that contains minimal additives and artificial ingredients. Limit treats and table scraps, as these often contain ingredients that might upset your dog's stomach.

3. Schedule Regular Health Check-Ups

Schedule regular check-ups with your veterinarian to monitor your dog’s overall health. Early detection of any issues can make them easier to manage and prevent more severe problems from developing.

4. Ensure Access to Fresh Water

Always make sure your dog has plenty of fresh water to drink. Proper hydration supports digestion and overall health, helping to prevent food intolerance.

5. Keep an Eye on Your Dog’s Behavior

Regularly observe your dog’s behaviour and overall health, especially after meals.

Changes in energy levels, mood, or physical symptoms can signal a food intolerance.

Staying alert to these signs allows you to address potential issues early and keep your dog healthy and happy.

When to Seek Veterinary Help for Dog Food Intolerance Symptoms

While many cases of food intolerance can be managed at home, there are times when veterinary intervention is necessary.

Here is when you should seek professional help.

If your dog's symptoms are severe or persistent.
If your dog is losing weight or experiencing vomiting or diarrhoea that does not improve.
If your dog has severe skin reactions.
If your dog frequently suffers from ear infections despite treatment
If you notice blood in your dog’s stool or vomit.
If you have tried different diets and nothing seems to work.
If your dog seems to be lethargic or in distress.

Most importantly, when in doubt, consult your vet. They can diagnose food intolerances, recommend suitable diets, and provide expert care for your dog.

Living with a Dog with Food Intolerance

Managing a dog with food intolerance takes patience and consistency.

By following your vet’s recommendations—be it providing a suitable diet and incorporating the right supplements—you can significantly improve your dog’s quality of life.

Finding the proper diet might take some time, so do not get discouraged if you need to try different options.

With patience and persistence, you can help your dog feel better and live a longer, happier life.
