Anyone ever had this happen in a older dog?

We took Gizmo at 5 pm to the vet today for her yearly. She got the distemper, rabies, bordatella (without our permission). About 7:15 pm her whole snout, chin and neck was swollen and beet red, gums were very dark. Rushed her to the vet and they gave her a shot of a steriod and benadryl. Told us to give her another benadryl at bedtime and 3 times a day for the next 5 days. For precautions. She had a reaction to the vaccines they thought maybe the distemper as she didn't have it last year (said every other year because of her age). Maybe it was made thru a differant company. We wonder about the bordatella vaccine? We don't know. Now the Dr said distemper every 3 year and they will split it up and give the steroid and benadryl.  The weird thing was, he said before giving the shot, will you be home for awhile in case she has a reaction, we said yes. We haven't had this said to us since she was a puppy. Of course we had no plans but also thougt she won't have a problem, she never has before. Well, thank god we didn't go out, we would be in a bad situation if we did. Makes me cry! Whole thing scared us to death and just so odd.

Sharing just to say never assume they won't have a reaction and stay home, you never know!!!

So sorry, I know how scary it is. Good luck to you and your furbaby.

There is evidence that a modified live virus vaccine,  like parvo and distemper,  has a duration of immunity of 7 years, and may offer protection for life, when given after 6 months of age.   I firmly believe that once the dog gets their shots at one year of age,  no more vaccines need to be given, with the exception of the rabies vax, of course.  Given your dogs ages,  I would seriously consider not vaccinating again for anything except rabies, and do that every 3 years if allowed by law.   I'm glad everything worked out for Gizmo.
