1. **Mild Fever**: Your dog may develop a slight fever, which is a normal response as their body builds immunity.
2. **Lethargy**: It's common for dogs to feel a bit tired or lethargic after vaccination. They might want to rest more than usual for a day or two.
3. **Soreness at Injection Site**: Your dog may have some soreness or tenderness where the vaccine was administered. You can gently check the area; if it seems swollen or painful, it should resolve within a day or two.
4. **Loss of Appetite**: Some dogs may not feel like eating immediately after vaccination. This is generally temporary, and they should regain their appetite shortly.
5. **Mild Diarrhea**: In some cases, dogs may experience mild gastrointestinal upset, including diarrhea. Monitor their hydration and ensure they are drinking enough water.
6. **Behavioral Changes**: Your dog might be a little more clingy or anxious than usual. This is typically temporary as they adjust post-vaccination.
**When to Contact Your Veterinarian**: If you observe any severe reactions, such as persistent vomiting, difficulty breathing, swelling of the face or limbs, or any other concerning symptoms, contact your veterinarian immediately. Severe reactions are rare but can occur.
Overall, most dogs will only experience mild side effects and will return to their normal selves within a couple of days. It's always a good idea to discuss any concerns with your veterinarian before and after vaccination to ensure your dog's health and well-being.
