Putative peanut allergy-induced urticaria in a dog.
1BK21 Basic & Diagnostic Veterinary Specialist Program for Animal Diseases and Department of Veterinary Internal Medicine, College of Veterinary Medicine, Konkuk University, Seoul, 143-701, South Korea.
Summary
A dog experienced a severe allergic reaction, including vomiting and skin rash, after eating peanuts. This case highlights peanut hypersensitivity as a cause of urticaria in dogs.
Area of Science:
- Veterinary Dermatology
- Canine Allergy Research
- Toxicology and Pharmacology
Background:
- Food hypersensitivity reactions are increasingly recognized in dogs.
- Urticaria, characterized by hives and swelling, can be triggered by various allergens.
- Peanut allergy is common in humans but rarely reported in canine cases.
Observation:
- A 9-year-old, spayed male schnauzer presented with acute gastrointestinal signs (vomiting, diarrhea) and dermatological symptoms (generalized erythema, pruritic urticaria, conjunctival hyperemia).
- The clinical presentation and histopathological findings were consistent with an allergic hypersensitivity reaction.
- Symptoms rapidly resolved following treatment with prednisolone and antihistamines.
Findings:
- This case presents the first documented instance of urticaria in a dog directly linked to peanut ingestion.
- The study confirms peanut as a potential allergen causing acute hypersensitivity in canines.
- Rapid therapeutic response to corticosteroids and antihistamines indicates a typical allergic pathway.
Implications:
- This report expands the differential diagnosis for acute urticaria and gastrointestinal distress in dogs.
- Veterinarians should consider food allergens, specifically peanuts, in cases of unexplained hypersensitivity reactions.
- Further research into canine food allergies is warranted to understand prevalence and specific triggers.

01:30Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
01:30Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...

Overview
01:30Hypersensitivities
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

01:27Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
