Plain-English summary
A dog with Japanese cedar pollen allergies developed oral allergy syndrome after eating fresh tomato. The dog showed an immune response to both the cedar pollen and the tomato, indicating a cross-reaction between the two allergens. This means that the dog's body mistakenly recognized the tomato as a threat due to its existing allergy to cedar. If your dog has similar allergies, it's best to avoid giving them tomatoes and consult your veterinarian for alternative safe foods.

Abstract
A dog with Japanese cedar (Cryptomeria japonica, CJ) pollinosis had oral allergy syndrome (OAS) after ingesting fresh tomato. The dog showed specific IgE to both CJ and tomato allergens. As a negative control, twenty dogs without atopic dermatitis that had no exposure to tomato and no specific IgE to CJ allergen were used. They had no specific IgE to tomato allergen. Furthermore, IgE cross-reactivity was observed between CJ and tomato allergens in the dog. We found that OAS induced by tomato exists in the dog and there is a relationship between CJ and tomato allergens.
