Anaphylaxis is a severe, life-threatening allergic reaction that can occur in pets, most commonly after an insect sting, medication, or a vaccine. ⚠️ It comes on very quickly, usually within minutes to an hour.
Signs to watch for include sudden vomiting or diarrhoea, collapse, difficulty breathing, a swollen face or hives, pale gums, and extreme weakness.
🚨 Anaphylaxis is a true emergency, so if you suspect your pet is having a reaction, contact our clinic or your nearest emergency animal hospital immediately.
