Why would my 2-month puppy need both Sentinel and Heartgard?

Hi there. While there's technically no reason that these two medications can't be used together, they are both heartworm preventatives - so there's quite a bit over overlap in what they do, and both should not be needed at the same time. If your pup is currently on Interceptor and you want to add a second medication to cover fleas, I would recommend using something like Nexgard or Bravecto - these are flea/tick meds only, so you wouldn't be treating her unnecessarily for heartworms with two different meds.

Heartgard and Sentinel are both good options for heartworm prevention - just make sure to check the minimum weight requirements, since I'm not sure how much your puppy weighs. He will also need to be vaccinated against distemper, parvo, and other serious illnesses that are common in puppies, and should also be dewormed if this hasn't been done yet. You should be able to make an appointment with your local vet to have all of these things done - the vet can also prescribe an appropriate heartworm prevention for your pup at that time :)

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!

Heartguard Plus also controls roundworms and hookworms, so there is no need to give the Nemex 2 now. However you should give your puppy Nemex in about two to three weeks in order to hit the worms that hatch from the eggs the Heartguard did not catch.

I would contact your veterinarian for specific advice for Kera, but I can give you the following information. The two ingredients in Sentinel are very safe and there is a moderate dosage range. You don't mention Kiera's weight, but depending on her weight, repeating Sentinel may still be within her dosage range even if you gave the Sentinel on the 28th. I would also ask your veterinarinan about when you purchased the Sentinel since that may help you determine (with the number of tablets you have left) if you gave her one last month or not. Finally, it is generally recommended to repeat heartworm medication if you are not sure you gave it since heartworms and intestinal parasites can cause significant disease. I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

Hello and thanks you for your post on Petco Pet Education Center, formerly Petcoach this afternoon! Yes, this should be okay. Although both are oral heart worm and intestinal parasite preventatives and typically speaking, giving two heart worm preventatives together or within a short amount of time is not recommended, combining these two preventatives together accidentally one week apart should not result in a negative reaction. Sam may have some transient diarrhea or vomiting, however. I hope this helps put your mind at ease and best wishes to you and Sam!

Hi there. Your pup is old enough to start on heartworm prevention now. I would suggest using Heartgard or Sentinel - both of these are fine for a pup who is 9 weeks old and weighs 3.5 pounds, and both are very safe in general. Puppies under six months of age do not need to be tested first.
