Allergic reactions to vaccines in dogs are rare but can occur. Signs of an allergic reaction to a vaccine may include swelling at the injection site, hives, itching, facial swelling, vomiting, diarrhea, difficulty breathing, or collapse. If you notice any of these symptoms after your dog receives a vaccine, it's essential to contact your veterinarian immediately for further guidance. In severe cases, an allergic reaction can lead to anaphylaxis, a life-threatening emergency. Your veterinarian may recommend antihistamines or other medications to manage the reaction. It's crucial to follow your vet's advice and monitor your dog closely after vaccinations.
