My dog accidentally got a double carprofen dose. Is she okay?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Female | 12 years and 11 months old | 18 lbs

I give my 12 year old Dachshund 25 mg of carprofen on mornings that she has trouble with her back legs. Unbeknownst to me, somebody already gave her 25 MGs of carprofen 4 hours ago and I just gave her another dose of 25. Is there any concern here?

Hi there, and thanks for using Petco Pet Education Center, formerly Petcoach! Fortunately, in my experience, it's very uncommon for a single extra dose of carprofen to cause any significant problems. With NSAID (non-steroidal anti-inflammatory drugs) overdoses in dogs, the two things we're most concerned about are stomach ulcers and possible kidney damage. These usually occur with doses above 20 mg/kg, which for a 25 pound dog would be about 227 mg. Since Tootsie only got 50 mg total this morning (about 4.4 mg/kg), it's unlikely that you will see any serious issues related to this. To be safe, you should monitor her for the next 24 hours for any signs of a problem, such as vomiting, acting lethargic, or not eating. If you have any concerns, I would recommend taking her to an emergency clinic to be seen.

    Hello and welcome to Petco Pet Education Center, formerly Petcoach, This SHOULD be OK. Skip the next dose, give a big meal, and monitor closely. Any signs of vomiting, diarrhea, sore abdomen, or any other concerns get Bunny to a vet right away Best of luck with Bunny!

    Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. While this is not ideal, a double dose of Carprofen given one time should not cause any issues. I recommend monitoring for an GI upset such as vomiting or diarrhea, but think that these signs will be very unlikely. I hope this is helpful!
