I accidentally gave my puppy too much amoxicillin. Is he okay?

Updated on September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | unneutered | 2 months and 13 days old | 12 lbs

How easy is it to overdose amoxicillin? My vet told me to give my puppy 1.5 mL morning and evening, but unfortunately the syringe was difficult to read and I accidentally gave him 2.5 mL. Should I be worried?

Hello. Amoxicillin is a very safe medication with a large range of appropriate doses. I would not worry at all about this one time overdose. Just continue with the 1.5 ml at the next scheduled time. Thanks for using Petco Pet Education Center, formerly Petcoach.

    Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It should not cause any problems to Max. Some dogs develop mild diarrhea after overdosing this antibiotics but there should not be any more serious side effects. Please, monitor Max at home and continue antibiotics as prescribed. There is no need to skip the next dose.

My 12lb dog took 500mg amoxicillin. Is this an overdose? Will he be okay?
Hopefully Chappo will only experience GI effects for this overdose. However, in some cases Amoxicillin overdose can cause neurological side effects, elevated liver enzymes and even cardiac issues. Do not give Chappo any more amoxicillin until you are able to get him in to your veterinarian.

My cat ate amoxicillin by mistake. Will he overdose or be okay?
I would not be overly concerned, although the recommended dose is 5-10mg/lb (and an 8lb cat would have consumed approx 15mg/lb) it does have a wide safety margin and overdose symptoms are very rare. I would expect some mild gastrointestinal upset and a probiotic would be helpful to reduce the impact on the natural gut balance

Accidentally gave my dog a double dose of Nisamox. Is she okay?
Since Amoxicillin (the ingredient of Nisamox) has a very wide safety margin, you do not have to worry, Just keep on medicating her as prescribed, ie the next dose of 1/2 tablet tomorrow morning. No need to worry.

My 50lb dog ate human amoxicillin. Will he be okay or get sick?
Most likely this amount of amoxicillin is not going to cause Theodore any harm. However any medication can cause GI irritation like vomiting and diarrhea. IF you notice any diarrhea I would recommend trying a bland diet for 12-24 hours of boiled chicken and white rice. If this does not help than Theodore should go see a vet for medications to resolve the GI upset. Hope that helps . thanks for using pet coach

My dog accidentally got a double dose of doxycycline. Is he okay?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The maximum dose of doxycycline is 10mg/kg twice daily (or 20mg/kg/day). If you gave Chylo around 33-35mg that is 20mg/kg and he should be fine. Do not give him any more for 24 hours. Doxycycline is very hard on the stomach so he may have vomiting. I hope this helps and have a great day!

My dog accidentally took too much antibiotic. Will she be okay?
That's ok, this happens. Lina should be fine; at most, you may see some stomach upset but this won't cause any serious problems. Just be sure to give it to her once a day from now on. I hope this helps!

Is human amoxicillin safe for my dog, or does it need dog amoxicillin?
Thanks for using Petco Pet Education Center, formerly Petcoach! Yes, human amoxicillin is the same that is used in dogs. Make sure to check with your veterinarian to make sure that she would benefit from this. Good luck and have a great day!
