my dog is on temarilp and was on pred before and it can cause aggression but never saw it in my dog so not likely - she probably does not feel well is why she is acting out - vaccine reactions can happen up to 90 days after a vaccine and sometimes affect their immune system for life like my dee dee
Next time when doing shots only rabies as i would titer for everything else in a small dog go to a holistic vet as they do not get the full dose of rabies like most vets and the rabies vaccine says for up to a 90lb dog and it says for healthy dogs only
Also in small dogs do vaccines separately - here is some info on rabies vaccine
