Is it safe to combine Seresto collar and Sentinel for dog flea/tick?

Updated On September 23rd, 2025

Pet's info: Dog | Beagle | Male | neutered | 5 years and 9 months old | 40 lbs

We are giving our 40 pound beagle the sentinel spectrum, it's for heartworm, fleas and says treats and controls tapeworms, whip,round and hook worms. It is a chewable. Is it to much to also put a seresto 8 month collar on him also? Is it necessary?

It is certainly not too much to use a Seresto collar with Sentinel! In my experience, Sentinel alone is not sufficient for proper flea control, but is great for heartworm and intestinal parasite prevention. The Seresto collar will prevent ticks and fleas, which is quite important. To answer your question, yes, use both! :-)
