What to Expect at the Vet
Allergic reactions in dogs range from mild hives and facial swelling to severe anaphylaxis with breathing difficulty and cardiovascular collapse. Common triggers include insect stings, vaccines, medications, and food. Mild reactions are treated with antihistamines and steroids, while anaphylaxis requires epinephrine, IV fluids, oxygen support, and emergency monitoring.
This is classified as a moderate emergency. Seek care within 1-2 hours.
Note: Most allergic reactions in dogs are mild (hives, facial swelling) and resolve quickly with an antihistamine injection ($200-$400). True anaphylaxis is rare but requires aggressive emergency treatment. Brachycephalic breeds (Bulldogs, Pugs) are at higher risk for airway compromise.
Your veterinarian will perform an initial examination ($50-$150) followed by diagnostic tests ($50-$300) to determine the appropriate treatment approach. Treatment costs ($50-$750) vary based on the specific intervention needed. Hospitalization and monitoring ($50-$1,200) may be required.
