Allergies and intolerances can both cause discomfort for dogs, but they are distinct conditions with different underlying mechanisms and symptoms. In this blog post, we'll explore the differences between allergies and intolerances, how to identify them, and what you can do to help your dog feel better.
Allergies
Definition: An allergy is an immune system reaction to a substance (allergen) that is typically harmless to most animals. Common allergens include certain foods, pollen, flea bites, and environmental substances like dust mites.
Mechanism: When a dog is allergic to something, its immune system mistakenly identifies the allergen as a threat and mounts an exaggerated response. This can lead to inflammation and a variety of symptoms.
Symptoms: Allergic reactions can manifest as:
Skin issues: Itching, redness, hives, swelling, hot spots, and chronic ear infections.
Respiratory issues: Sneezing, coughing, and wheezing (though less common in dogs than in humans).
Digestive problems: Vomiting, diarrhea, and flatulence.
Behavioral changes: Increased scratching, licking, or chewing at specific areas.
Intolerances
Definition: An intolerance is a non-immune response to a food or substance that causes digestive upset. It occurs when a dog’s digestive system cannot properly process certain ingredients.
Mechanism: Intolerances often involve enzymatic deficiencies, such as lactose intolerance, where the dog lacks the enzyme lactase needed to digest lactose in milk.
Symptoms: Intolerance primarily affects the digestive system and includes:
Digestive issues: Diarrhea, vomiting, bloating, gas, and stomach pain.
Less common symptoms: In severe cases, it may lead to weight loss or a poor coat condition due to malnutrition from chronic digestive issues.
Spotting the Difference Between An Allergy & An Intolerance
Key Factors to Consider:
Onset of Symptoms:
Allergies: Symptoms may appear within minutes to hours after exposure to the allergen.
Intolerances: Symptoms generally take longer to appear, often several hours to a day after consuming the problematic food.
Types of Symptoms:
Allergies: Often include skin and respiratory issues in addition to digestive problems.
Intolerances: Primarily cause digestive upset without skin or respiratory symptoms.
Reaction to Small Quantities:
Allergies: Even a tiny amount of the allergen can trigger a reaction.
Intolerances: The severity of symptoms usually depends on the quantity consumed. Small amounts may cause mild or no symptoms, while larger amounts trigger a more pronounced reaction.

Identifying Food Intolerances
One bout of gastric upset is not enough to determine that your dog has a food intolerance. It’s essential to look for patterns and repeated reactions to specific foods. Symptoms of food intolerance often include digestive issues such as diarrhea, vomiting, bloating, gas, and stomach pain. However, these symptoms can also be caused by other factors, so it’s crucial to monitor your dog’s reactions over time.
The Challenge of Changing Diets
If your dog is transitioning from a nutrient-poor dry kibble to a diet with real protein and whole foods, it will take time for their gut to adjust to the healthier diet. The gut flora, which consists of the beneficial bacteria in your dog’s digestive system, needs time to adapt to new foods. During this transition period, your dog might experience temporary digestive upset, including gas, bloating, or loose stools. This doesn’t necessarily indicate a food intolerance but rather an adjustment phase as their digestive system gets used to processing more natural, nutrient-dense foods.
Can You Overcome Food Intolerances in Dogs?
Food intolerances can be a frustrating issue for dog owners, but there are strategies to manage and sometimes even overcome these challenges. While true food intolerances involve a dog's inability to digest certain ingredients properly, making it a lifelong condition, there are ways to mitigate mild-moderate intolerances and their impact.
Managing Food Intolerances
Identify the Problematic Food:
Elimination Diet: The best way to identify intolerances is through an elimination diet. Start with a novel protein and carbohydrate that your dog has never eaten before. Gradually reintroduce suspected foods one at a time to see which ones cause symptoms.
Veterinary Consultation: Work with your vet to ensure the elimination diet is balanced and to rule out other potential health issues.
Avoidance:
Dietary Changes: Once you've identified the problematic food, avoid it entirely. Read ingredient labels carefully to ensure the food isn't included.
Gradual Reintroduction:
Desensitization: In some cases, small, controlled amounts of the problematic food can be reintroduced gradually over time to see if the dog's tolerance improves. This should only be done under veterinary supervision.
Supplementation:
Digestive Enzymes: Adding digestive enzyme supplements to your dog's diet can help break down certain foods, reducing symptoms of intolerance.
Probiotics and Prebiotics: These supplements can support a healthy gut microbiome, which may improve overall digestive health and potentially reduce the severity of food intolerances.
Balanced Nutrition:
Alternative Foods: Ensure your dog receives balanced nutrition by providing alternative sources of the nutrients found in the foods they can't tolerate. This may involve working with a vet or pet nutritionist to formulate a suitable diet.
Overcoming Specific Intolerances
Lactose Intolerance:
Lactase Supplements: Lactase enzyme supplements can help dogs digest lactose, allowing them to consume dairy without symptoms. Use these under the guidance of a vet or avoid diary completely.
Grain Intolerance:
Grain-Free Diets: Switch to grain-free diets that use alternative carbohydrate sources like sweet potatoes.
Protein Intolerance:
Novel Proteins: Use novel proteins that your dog has not been exposed to before, such as kangaroo, duck, or venison.
Long-Term Management
While some food intolerances can be managed to the point where symptoms are minimal or non-existent, it’s important to note that true intolerances may not be completely "overcome." Ongoing management typically involves:
Regular Monitoring: Keep an eye on your dog’s symptoms and overall health. Adjust their diet as needed and consult with your vet regularly.
Avoidance of Triggers: Continue to avoid known triggers and be cautious with new foods or treats.
Veterinary Support: Maintain regular check-ups with your vet to ensure your dog’s nutritional needs are being met and to address any emerging issues promptly.
With careful management and support, dogs with food intolerances can lead happy, healthy lives. Always work closely with your veterinarian to develop the best plan for your dog's specific needs.

Managing Allergies in Dogs
Managing allergies in dogs involves identifying the allergens, minimizing exposure, and providing appropriate treatment to alleviate symptoms. Here's a detailed guide on how to manage allergies in your furry friend:
Identifying the Allergens
Veterinary Consultation: Start with a visit to the vet. They can perform tests such as blood tests, skin tests, or elimination diets to identify specific allergens.
Observation: Keep a diary of your dog's symptoms and potential triggers. Note when and where symptoms occur, and any changes in diet, environment, or routine.
Minimizing Exposure to Allergens
Environmental Allergies:
Regular Cleaning: Keep your home clean and dust-free. Vacuum regularly and wash your dog’s bedding frequently.
Air Purifiers: Use air purifiers to reduce airborne allergens like pollen, dust mites, and mold spores.
Grooming: Bathe your dog regularly with hypoallergenic shampoos to remove allergens from their coat. Wipe their paws and fur after they come in from outside to remove pollen and other potential irritants.
Food Allergies:
Elimination Diet: Feed your dog a novel protein and carbohydrate source they haven’t had before for at least 8-12 weeks. Gradually reintroduce other foods to see if symptoms return.
Hypoallergenic Diets: Use specially formulated hypoallergenic diets that are free from common allergens like beef, chicken, dairy, and grains.
Flea Allergies:
Flea Control: Use veterinarian-recommended flea prevention treatments. Regularly check your dog for fleas and treat any infestations promptly.
Environment Treatment: Treat your home and yard for fleas to prevent re-infestation.
Treating Allergy Symptoms
Medications:
Antihistamines: These can help reduce itching and other allergic reactions. Always use under veterinary guidance.
Topical Treatments:
Natural Shampoos: Use anti-inflammatory or anti-itch shampoos to soothe irritated skin comprised of soothing all-natural ingredients that wont irritate the skin.
Dietary Supplements:
Omega-3 Fatty Acids: These can help reduce inflammation and improve skin health. Fish oil supplements are a common source.
Probiotics: These can help support a healthy immune system and improve overall gut health, which may reduce allergic reactions.
Monitoring and Adjusting Treatment
Regular Vet Visits: Keep up with regular veterinary check-ups to monitor your dog's condition and adjust treatment as needed.
Observe and Record: Continue to observe your dog’s symptoms and response to treatments. Keep a detailed record to share with your vet.
