Has anyone ever had their puppy have a reaction to a vaccination? My puppy had a DHPP vaccination and a dewormer pill at around 4:00 pm today. It has been 5 hours and my puppy is very hyperactive and aggressive tonight. We have tried running him around outside several times. He can't seem to settle down. I have heard of dogs being lethargic after vaccinations, but not hyperactive. Any help is much appreciated.....h*lp. He appears to be breathing fine and isn't swelling at all, but he just can't seem to settle down.
