Welcome! My name isXXXXX am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Talon.
It happens even to doctors and technicians. No problem.
Well, if you are confident about 1/2 of the vaccine was not admnistered, there would be no harm in just giving another 1/2 now. Even if that results in a little more or a little less than the intended dose, that is not a concern.
Certainly, I would always advise monitoring for any vaccine reactions
, but not because of what happened.
The classic complications would be vomiting, facial swelling, or hives like reaction on the skin.
If you wanted to be a bit more proactive to try and avoid issues, no reason you can't give a dose of some benadryl 1 hour beforehand.
Benadryl can be given at a dose of 1mg per pound of body weight. Keep in mind, Benadryl tablets and liquids come in different sizes. So, an approximately 25 pound dog can get a full 25mg tablet or a half of a 50mg tablet. I usually avoid the liquid Benadryl in larger dogs (you would have to give too much of it).
Benadryl probably a good idea anyway since this is not just a distemper
, and you are giving a 7 way shot.
Please let me know if there is anything I did not cover for you. I hope that information has been helpful.
