My puppy missed his Giardia Flagyl. When's the latest to give it?

Updated on September 23rd, 2025

Pet's info: Dog | Shiba Inu | Male | neutered | 3 months and 15 days old | 23 lbs

My puppy has Giardia and we're giving him Flagyl that was prescribed to him. His regular schedule is 7am and 7pm however we missed his 7am dosage today and I'm wondering when is the latest time he can take it before we should just skip this dosage.

You can give a dose now an then match the next dose for the same time 12 hours later (ie: 9am/9pm). And then tomorrow go back to the 7am/7pm schedule if that is what works best for you. Dosing should be at least 8 hours apart.

Hope this answers your question. Best wishes.
