I want to address an important topic that every dog owner should be aware of – anaphylaxis from food. Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur in dogs, just like in humans.
In this article, we will explore the causes, symptoms, diagnosis, treatment, and prevention of anaphylaxis in dogs related to food allergies.
Roadmap
Diagnosing and managing allergies in dogs is a step-by-step process, and require adjustments when changes and relapses occur.
You’re in the management stage…

Key Takeaways
- Anaphylaxis can occur in dogs as a severe and potentially life-threatening allergic reaction, and it can be triggered by food allergens such as protein sources (beef, chicken, lamb, fish), grains (wheat, corn, soy), dairy products, eggs, artificial additives, and food colourings.
- Symptoms of anaphylaxis in dogs can include difficulty breathing, swelling of the face or tongue, hives or rash, vomiting or diarrhoea, weakness or collapse, increased heart rate, pale gums, and seizures. The severity and combination of symptoms may vary from dog to dog.
- Prevention through careful attention to a dog’s diet, reading food labels, avoiding feeding table scraps or human food, and being aware of potential allergens in treats and chews can greatly reduce the risk of anaphylactic reactions in dogs.
- Prompt veterinary care is essential in case of a suspected anaphylactic reaction, and treatment may include intravenous fluids, oxygen therapy, epinephrine injection, antihistamines, and corticosteroids.
Causes of Anaphylaxis in Dogs
An anaphylactic shock from food proteins has been reported but is very rare. Most acute allergic reactions in dogs are to insect stings or bites from bees, wasps, and venomous ants, or snakes. Medications and vaccines are also known to cause anaphylaxis in dogs.
If anaphylaxis in dogs would occur, it can be triggered by an allergic reaction to specific components in their food. Common allergens in dog food that can cause anaphylaxis include:
- Protein sources such as beef, chicken, lamb, and fish
- Grains like wheat, corn, and soy
- Dairy products
- Eggs
- Artificial additives and preservatives
- Food additives like food colourings
Symptoms of Anaphylaxis in Dogs
Anaphylaxis can manifest suddenly and progress rapidly, making it a life-threatening emergency. Some common symptoms of anaphylaxis in dogs include:
- Difficulty breathing or shortness of breath
- Swelling of the face, lips, or tongue
- Hives or rash
- Vomiting or diarrhoea
- Weakness or collapse
- Increased heart rate
- Pale gums
- Seizures
It’s important to note that the severity and combination of symptoms can vary from dog to dog, and not all dogs may exhibit the same signs.
Treatment of Anaphylaxis in Dogs
Anaphylaxis in dogs is a medical emergency that requires immediate and aggressive treatment. If you suspect your dog is experiencing an anaphylactic reaction, you should seek veterinary care immediately.
Treatment may include:
- Intravenous fluids to stabilize blood pressure and hydration
- Oxygen therapy to support breathing
- Epinephrine injection to reduce severe allergic reactions
- Antihistamines and corticosteroids to reduce inflammation and allergic responses
- Close monitoring of vital signs, including heart rate, blood pressure, and oxygen levels
Prevention of Anaphylaxis in Dogs
Preventing anaphylaxis in dogs related to food allergies, if it has occurred, involves identifying and avoiding the trigger food. If your dog has experienced an anaphylactic reaction, your veterinarian may recommend a specialized diet that avoids the allergen.
Additionally, carefully reading and understanding food labels, avoiding feeding table scraps or human food, and being aware of potential allergens in treats and chews can help prevent anaphylaxis in dogs.
Possible Challenges and Criticisms
As with any medical condition, there may be challenges and criticisms related to the diagnosis and treatment of anaphylaxis in dogs.
- Anaphylactic shock from food proteins is very rare though it has been reported, and is therefore potentially over-diagnosed. Food allergic to certain proteins on the other hand is common and might be mistaken for the cause of an anaphylactic episode.
- Difficulty identifying the specific food allergen that triggers the anaphylactic reaction, as there may be multiple potential allergens in a dog’s diet.
- Misinterpretation of symptoms, as some symptoms of anaphylaxis in dogs, may overlap with other medical conditions.
- Compliance with an elimination diet, as it requires strict adherence to a specific diet for an extended period, which may be challenging for some dog owners.
Personal Opinion
As a veterinarian with experience in treating anaphylaxis in dogs, I have seen firsthand the devastating effects of this severe allergic reaction. In my opinion, prevention is key, and careful attention to a dog’s diet and potential allergens can greatly reduce the risk of anaphylaxis.
I believe that education and proactive measures, such as reading food labels and avoiding feeding table scraps or human food, can play a significant role in preventing anaphylactic reactions in dogs.
Conclusion
In conclusion, anaphylaxis from food can occur in dogs and can be a life-threatening condition. It is important for dog owners to be aware of potential food allergens, recognize the symptoms of anaphylaxis, and seek immediate veterinary care if their dog shows signs of an allergic reaction.
Prevention through careful attention to diet, reading food labels, and avoiding potential allergens can greatly reduce the risk of anaphylactic reactions in dogs.
As a veterinarian, I emphasize the importance of education, proactive measures, and timely veterinary care to ensure the well-being and safety of our beloved canine companions.
