Need tick protection for dog on Sentinel Spectrum. What's safe?

You can use a Preventic collar, a Seresto collar, or a topical medication such as Frontline or K9 Advantix along with Comfortis for tick coverage. Or, if you prefer to stick with oral medications, you can switch from Comfortis to Nexgard or Bravecto - both of these cover both fleas and ticks, and are also very effective.

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.

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!

You have a few options. If you want an all in one product, try Trifexis. Otherwise you will two separate products. You might try Simparica (fleas/ticks) and Interceptor (heartworm/intestinal worms). I also recommend to have Sparky's stool checked for worms in case that was a round worm. For that parasite, pets are often given bolus dewormings since people can get that worm. That will clear up the infection faster.

Great question! Nexgard kills the deer tick as well as fleas and American dog tick/rocky mountain tick, and lone star tick. It is an oral pill as well, so I would us that for your dogs. Because Nexgard doesn't protect again heartworms, you will have to give your dogs Heartgard as well, which is available by prescription only from the vet. Advantix is a spot on treatment that treats the same things as Nexgard, but you would also have to use Heartgard as well for the heartworms. These two medications (Nexgard and Advantix) are for dogs only. As for the cats, Simparica prevents five types of ticks, so this may work for your cats :-)

Thank you for submitting your question regarding Cujo. It is fine to give both medications. The Sentinel and Nexgard work in different ways for controlling fleas. The benefit of giving both is the boarder spectrum of protection as each product covers a variety of parasites. I hope this information helps!

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!
