My vet told us that dachshunds, red doxies especially, seem to have allergic reactions to the lepto and lyme vaccines. Lyme is very important for us to get because we live in the Holy Land of Lyme Disease here in CT. In any case, she won't give the two vaccines at the same time and she does half the vaccine in one spot and half in another. My brother's rat terrier/chi mix had an allergic reaction to one of the above (can't remember which). They were half way home and Josie started to swell up and couldn't breathe. They had to rush her back to the vet and get a Benadryl. Thankfully all turned out okay.
