My dog is sad days after shots but still eats. Is it vaccine related?

It has been 6 days since my one year old dog got her shots and she has been acting sad lately. Just lays in a blanket. She still has energy she eats and gets happy when she sees people

I am very sorry to hear that Bella isn't acting like herself. If the cause of her mood change were due to a vaccine reaction, typically you would see changes in the hours after the shots were administered. In addition, side effects and reactions from these shots do not typically last more than 12-24 hours. My suspicion is that whatever is bothering Bella has nothing to do with the vaccines. If she is still eating, drinking, peeing, and pooping, I wouldn't be too worried for the moment. Continue to monitor her for any serious changes in her health. If her energy level declines and any of the aforementioned things change in a negative fashion, I would consider speaking to your local veterinarian. Hope this helps you and Bella out!
