My small dog ate cow antibiotic. What are the risks to her health?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 10 lbs

My small dog (10 lbs.) chewed the end off of a partially used 10ml tube of cephapirin sodium for lactating cows. It is possible that she ingested at most half of the tube, maybe less. Could this cause any problems?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Mini getting into this. I don't think that this is going to be a problem but it is possible that Mini will develop some stomach/intestinal problems such as nausea, vomiting, diarrhea, cramping from the ingestion. If she ingested 1/2 of the tube, that's about 100-150 mg of the antibiotic which is well within the range for her normal dose if she was put on a similar antibiotic from your vet. I would monitor her and if signs develop and don't resolve, I would at least call your veterinarian and see what they advise. They may want to see her and then advise some treatment for her signs if they develop and don't resolve. Good luck with Mini.
