My dog got the wrong size Nexgard. Can I cut the chew in half?

Updated On September 23rd, 2025

Pet's info: Dog | Rat Terrier | Male | unneutered | 6 years and 3 months old | 17 lbs

Hello, I have a 17 pound dog and bought a nexgard for him. Only thing is, it arrived as the 24.1 to 60 pound nexgard. I found out is has double mg of the medicine, 28mg vs 68mg. Can I give him half of a pill for a month? Than you

With medications in tablet form, you can certainly cut them in half and still be sure that you are giving half of the medication. Unfortunately with chewable medications (like Nexgard, Heartgard, etc.), splitting a dose in half does not ensure that half of the medication will be given. The active ingredients are mixed throughout the chews, but not necessarily in a uniform way. To answer your question, no, you shouldn't give Frosty half of a Nexgard. Instead, see if you can exchange the product for the correct size. It's likely that your vet will be able to prescribe a single dose while you sort out the exchange process. I hope that everything goes well!

    Unfortunately for any of the chewable tablets, the medication may not be evenly distributed throughout the tablet, so the companies do not recommend dividing chewable tablets. So, I would recommend giving your 15 pound dog the 10-24 pound Nexgard and get the smaller 4-10 pound size for your 7 pound dog. Good luck! I hope that was helpful and answered your question.
