Why am I still seeing fleas on my dog after using NexGard®?
Adult fleas – the ones that you see on an infested pet – make up only ~5% of the total flea population. The developing stages (flea eggs, larvae and pupae) make up the other 95%. These developing stages can be found anywhere an infested animal spends time. Commonly infested animals, which spread flea eggs throughout their surroundings, include untreated pets, feral cats, opossums, coyotes, etc.
You are likely seeing NEW fleas on your pet, which are jumping on your dog as it moves through infested areas. These fleas will be killed quickly by NexGard® before they can reproduce. Depending on the severity of an already existing infestation, you may continue to see new fleas jumping on your pet for three months or more (depending on environmental conditions). To prevent new infestations, continue to give NexGard® MONTHLY throughout the year.

Does NexGard® need to be used even if I have an “Indoor dog"?
Yes—fleas are opportunists. Even if your dog only goes outside to do their business, they’re at risk of infestations from fleas and ticks. Fleas can even “hitchhike" into a home on people, and then jump to infest dogs. An infested pet will spread flea eggs throughout the house, which can survive in your carpet or the crannies of your wood floors and then mature to infest other animals in your home.
