If you know what vaccination it was, it would be great if you post for all of us. I know that there have been many dogs allergic to lepto and would be very curious to know if that was in there...
I am glad you caught it early and she is all better now. Give her kisses from our fur-babies
BTW-I always have my vet give my fur-babies only 1/2 of the vaccination and have luckilly never had any reactions (cross my fingers)...I will always do it that way. They all weigh under 5 lbs.
