Turbo & Princess had their DHP 1 yr booster shot couple of days ago. Turbo started scratching his face like mad. We were still in our vet's office & Princess was receiving her shot. I told the vet tech, something is wrong...he said it's just him scratching.
We get in the car, & he's rubbing his face all over the place! I called them while still in the parking lot & described what he was doing & they said to come back in.
Well, he had an allergic reaction & was given a cortisone shot & they kept him there for a few hours, they didn't charge me. On their record, it says DHLPP, but I was told they did not get the Lepto.
It's more common for pups to get allergic reactions to their 2nd set of core vaccines (one of Mimi's pups did), but it's rare to get an allergic reaction to annual booster shots...Turbo is special.
Come next year, I'm thinking of titer testing like dwerten mentioned. I like to follow Dr Jean Dodds vaccination protocal, but unfortunately not all vets are fans.
