That could be a vaccine reaction. You did not say however which type of medication you gave him for the fever and so I cannot advise if there are side effects to that or not. Please repost with the name of the medication and the active ingredient if needed. I also recommend to call his veterinarian and tell him what’s going on. The doctor needs to know that for any future vaccinations and may recommend some definitely pet safe treatments to give him. I hope this helps and please feel free to post any additional questions!
