Should my dog take both Sentinel Spectrum and Nexgard for parasites?

Updated On September 23rd, 2025

Pet's info: Dog | American Staffordshire Terrier | Male | unneutered | 2 months and 23 days old | 20 lbs

We just had his initial appointment with the vet for his shots and a general health check up he is completely healthy but they wanted to give him some preventative medications for fleas and ticks and also for heartworms tapeworms and hookworms. He gave me sentinel spectrum for all the worms and he gave me nexgard for the fleas and ticks but they both say they treat for fleas. Should I be giving him both of these medications or is it as unnecessary as I think? I don’t want to give him so many.

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!
