Bottom Line
While Bayer K9 Advantix II offers broad-spectrum pest protection, it's crucial to monitor dogs for any adverse reactions, especially during the drying period after application. Some users report a decrease in effectiveness against fleas and ticks compared to previous batches. If your dog has a history of allergies or sensitivities, it might be wise to consult a vet before use or consider switching to an alternative product that's proven effective, such as a chewable treatment.
