My two young dogs take Nexgard. They pee in a grassy area here in Florida. They have twice gotten tapeworms in spite of Nexgard. Why? Did the flea(s) bite before the product was effective?

Hi and thanks for you post this afternoon.
NexGard and Sentinel does not cover tapeworms. It helps prevent fleas which will help prevent the most common tapeworm in dogs. Dogs and cats get tapeworms through ingesting a flea. This happens often while itching or grooming themselves.
Tapeworms can be treated with Praziquantel which is part of Sentinel Spectrum (different from regular Sentinel) or can be given as a one time injection at your veterinarian's office.
Tapeworms can be rid of with a good flea preventative (which it looks like Rouge 1 is currently on) as well as tape worm deworming with Praziquantel if a tapeworm infection is present.
I hope this helps and best of luck to you and Rouge 1!
