Health & WellnessIs it safe to switch my dog from NexGard to K9 Advantix II now?
Yes, it's you can go ahead and switch now. The two products have different active ingredients (which is the point for your switch) and even if they didn't, you wouldn't overdose Pepe with doses two weeks apart, so you're good to go! I hope it helps! Thanks for using Petco Pet Education Center, formerly Petcoach
