If a bite or sting could cause an allergic reaction, which signs may appear?

• A. Collapse
• B. Vomiting and diarrhoea
• C. Rapid breathing
• D. All of the above

Answer: (D)

Allergic reactions to bites or stings can involve multiple body systems, not just the bite site. In a reaction, chemicals released in the body can cause the airway to swell and breathing to become rapid or difficult, leading to rapid or labored breathing. The reaction can also trigger shock, with weakness or collapse as blood pressure drops. The digestive system may be affected too, causing vomiting or diarrhoea. Because a bite or sting can lead to several of these signs, all of the listed signs may appear. If you notice any of these after a bite or sting, seek urgent veterinary care immediately.
