My 50lb pit mix had allergic reactions to both Nexgard and Advantix K9 III. Both same reaction, swollen eyes and snout with hives all over body. Was given benedryl and steroids over the course of weeks, both times. Vet wants to recommend another tick med, but I am refusing. Don’t want to do a trial and error on the dog. Anyone else have a dog that simply cannot tolerate any traditional tick/flea meds?
