My dog has had an anaphylactic reaction to a combined vaccine. He's about to start on filaria prevention, but do you think he'll be ok if it's tablets and not vaccines?
Does your dog has any mix from Collie breed?
Some breed can have reaction to vaccine. From my point of view in such a cases the vaccine should be separated and be given apart with one week or more days distance. For exampleinstead of a DHPPiL4 T, DHPPil4 one week and other week T vand see if the dog react again or not? If yes then dont vaccinate him anymore. Deworming also tablets are better but make sure he has no sensitivity to medicine.
