🚨 Allergic reactions in pets can happen fast 🚨
Facial swelling, hives, puffiness around the eyes or muzzle, vomiting, or sudden changes after a vaccine can be signs of an allergic reaction.
In this video, Dr. Lera shows what a vaccine reaction can look like and explains why timing matters.
If your pet ever has swelling, trouble breathing, weakness, vomiting, or seems off after a vaccine, call your veterinarian right away.
