Pet's info: Dog | Labrador Retriever | Male | neutered | 2 years and 1 month old | 110 lbs
My 110 lb 2 year old lab has fleas. I used Nexgard and he threw it up in the first hour of taking it so i threw it out. Then i put the pet armor topical on him but that only kills fleas. Can i use the seresto collar three days after the topical? I do not want to poison him accidentally with all of the medicine please help thanks
