1. **Mild Fever**: It's not uncommon for dogs to experience a slight fever after vaccination, which usually resolves within a day or two.
2. **Lethargy**: Some dogs may appear tired or less active than usual for a short period following vaccination, which is generally temporary.
3. **Soreness at Injection Site**: You might notice some swelling or tenderness at the site of the injection. This usually goes away on its own within a few days.
4. **Loss of Appetite**: A temporary decrease in appetite can occur after vaccination. If it persists for more than a day, consult your veterinarian.
5. **Mild Diarrhea**: Some dogs may experience mild gastrointestinal upset, including diarrhea, after receiving their vaccines.
6. **Allergic Reactions**: In rare cases, dogs can have allergic reactions to vaccines, which may manifest as hives, swelling, vomiting, or difficulty breathing. This requires immediate veterinary attention.
It's essential to monitor your dog for any unusual symptoms after vaccination and consult your veterinarian if you have any concerns. Most side effects are mild and resolve quickly, and the benefits of vaccination far outweigh the risks.
