My dog throws up NexGard with food. What can stop the nausea?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Female | spayed | 7 years and 1 month old

Even when given with food my dog vomits with every NexGard doss. Is there a recommended food (and how much) that would help prevent the nausea??

Poor pup! Nausea is less common with Nexgard than with some of the other oral flea meds available (such as Comfortis or Trifexis), but can still happen in some dogs. Normally, giving the pill with a meal helps to prevent this, but it doesn't sound like it's helped much for your dog. It normally doesn't matter what type of food you give it with, because the purpose of giving with a meal is to slow absorption of the medication so that it's more gradual - it's the presence of food in the stomach that helps, rather than any specific ingredients. So if this hasn't helped with your pup, you may want to try a different medication next month - the vomiting isn't dangerous and is not a sign of toxicity problems or any other serious issues, but I know it's no fun for either of you to have him vomit every month! He might do better with Bravecto, or a topical flea/tick med such as K9 Advantix.

    Most likely your pets stomach just doesn't agree with this medication altogether. I would recommend switching to something else to avoid adverse symptoms, because switching food will likely not stop the vomiting. I would recommend trying either Bravecto (oral pill that lasts 12 weeks for flea/tick prevention) or stick with a topical such as Advantix or Advantage Multi (preferred).
