I think it starts working right away.  My dogs have not had any fleas using this product.  If your dog has fleas now, I'm not sure.  It shouldn't take long though and my dogs haven't had any adverse reactions from this medicine. 

@ Quinn26. A tick can still bite your dog when taking Nexgard. Nexgard kills ticks and fleas when they bite your dog. It works very well for fleas. I do not know about that particular type of tick. I have been told the Seresto collar works really well for preventing tick bites. That is the opinion of a dog owner whom lives a heavily wooded New England area

We have used Simparica in the past for our dogs, both large and small breeds. It didn't seem to work very well so we switched to Nexgard which we have been using for the past year and so far it has worked well for keeping the fleas away and no problem for our pets digestion.

Yes, I live in Southern California and that is what I do. I've never had a problem.

Hello we live in Wisconsin. I have been told ticks can only survive above 30 degrees. When snow falls and it is cold during these months I do stop using. However- fist sign of spring she’s back on it! 

Thank you for contacting Drs. Foster and Smith with your question concerning NexGard. NexGard is a prescription drug, meaning that your veterinarian would determine the appropriate amount for your dog and write the prescription for that amount. In general, for dogs over 121 pounds, the pharmaceutical company that manufactures NexGard recommends that the appropriate combination of tablets is given. For example, a dog weighing 158 pounds would receive one tablet of the 60-121 pounds (136mg) size and one tablet of the 24.1-60 pounds (68 mg) size. We recommend discussing all medications and dosages with your veterinarian, as well as following your veterinarian’s recommendations. We hope this information is helpful. Thanks again for contacting us. Best regards, Veterinary Services Drs. Foster & Smith

We have been having a terrible flea problem this year & our 1 dog, which is a 9 year old terrier mix, is very allergic to fleas. Several topicals that we have applied have failed to rid her of fleas for more than two weeks. Both our vet and also our doggie dermitologist have recommended Nexgard and have told us you can apply both & that there is no interaction. I trust that since both tell me it is safe & they are professionals in their field, it is OK, but I would check with your vet first. They had me apply one first and at the 2 week mark apply the other. Nexgard really worked & will now try it alone. I would not use both on the same day.

Hello! You can either purchase a 3 month or 6 month supply for your dog. You will need to choose the correct box according to your dog's weight. The Dose is one chewable tablet once a month, so you will get either 3 or 6 doses depending on which option you choose to purchase.
