What OTC flea treatment is safe for my diabetic dog on Sentinel?

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! Yes, there is no harm in using a a topical flea treatment along with sentinel. Advantage II, K9 Avdantix, or Frontline Plus or Gold for example would all be okay. I hope this helps!

Hello, sentinel has an IGR which essentially prevents immature fleas from becoming adult fleas. It does not kill adult fleas. You can still use an adulticide such as advantix spot on to kill the adult fleas. Hope this helps and best of luck.

You're correct that Sentinel is considered a "passive" flea control product - it doesn't kill adult fleas, just keeps their eggs from being able to hatch. Capstar would be quite effective at killing any fleas that he currently has on him. It shouldn't be necessary to wash bedding, etc. since the Sentinel will ensure that the fleas are not able to reproduce. In my experience, some dogs do fine with Sentinel as their only flea control method if they are in an environment where they are rarely exposed to fleas. But if you're seeing fleas from time to time, or if your dog has flea allergies or other skin sensitivities, then I would recommend using an adulticide like Nexgard or Bravecto along with his Sentinel.

Since it's been at least two weeks since Oreo last received a flea treatment it's fine to apply Frontline or Advantage to him now. Of the two, I recommend Advantage. The best flea treatments are the ones like Frontline or Advantage, I never recommend OTC ones because they are poor quality and do not work well. I hope this helps!

Hi and thanks for your post! Yes this is okay. Sentinel does not kill adult fleas, just the eggs. Sentinel also does not prevent ticks as you mentioned in your question. Advantix does, however. I hope this helps!

Hi there! Yes, Advantix would be a very reasonable choice to use along with Sentinel Spectrum. You could also use Nexgard or Bravecto for tick coverage, if you prefer an oral medication instead of topical.
