My dog accidentally got two doses of Vetmedin. Should I worry?

Updated on September 23rd, 2025

My 10 LB dog got two doses of vetmedin this morning. Instead of 1/2 of 2.5 tab she received 1/2 from both of us should we be concerned?

Hello and thank you very much for your question. Your dog is so very lucky to have such concerned and caring parents.

Vetmedin is administered at a dosage of 0.5 mg per kilogram of body weight. A kilogram is equal to 2.2 pounds. If I am reading your question correctly, you both gave 1.25 mg to your dog this morning. That is the total daily dose recommended for a dog your size. Even though the dosage should be divided into two doses given approximately 12 hours apart, it is absolutely fine in this situation that the entire daily dosage was given once.

So, no, you have no reason to be concerned with what happened this morning. Your dog should be absolutely fine. Please do not give any doses for the rest of the day and tomorrow morning, go back to your regular 1/2 tablet every 12 hours dosing schedule.

I hope I have given you the information you needed. Have a great day

    If he is due another dose this evening, skip it. If he is not due another dose until tomorrow then I would just monitor him during the day but it should not be a concern. Hope this helps, thank you fir using Petco Pet Education Center, formerly Petcoach !

A human accidentally swallowed dog's 5mg Vetmedin. What now?
The active ingredient of Vetmedin is Pimobendan. This is a medication that is also used in humans, therefore I suggest you call a human poison control or your doctor or a hospital to find out what to expect and whether the dosage is harmless or not. From articles I found the normal human dose is 2.5 mg, so 5mg is double and I strongly suggest your consult with a doctor. We are veterinary doctors and not qualified to assess this. Please call your nearest hospital.

My small dog ate Vetmedin. Is this heart medication safe for her?
Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Harper. The dose she ate is actually below what the recommended dose would be for a dog her weight, so there is no risk of overdose. This single, low dose should not be a problem. Just don't let her get any more. I hope this helps!

Dog losing weight: At what weight should Vetmedin 1.25mg dose be lowered?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The dose of Vetmedin is 0.25mg/kg twice daily. So for a 10 lb dog I would prescribe the 1.25mg tablet to give every 12 hours. I would go to 1/2 of a 1.25 mg twice daily around 6-7 lbs. I hope this helps!

Is it safe to give my dog Vetmedin an hour early for a few days?
Yes, this shouldn't cause any problems at all. Ideally, we want to space the dosing out to get as close to every 12 hours as possible, but being an hour or so off from time to time should be just fine :)

My dog threw up his heart meds, then got more. Is it an overdose?
HI, thanks for using Petco Pet Education Center, formerly Petcoach! I would need to know the milligrams (mg), how many tablets of each and how often he receives the medications to be 100% sure. But he likely will be fine! If he receives any of these medications twice daily just skip tonight's dose. Even if they are just once a day medications he will likely be fine. Call your Vet tomorrow to discuss it with them. I hope this helps and have a good day!

My 12lb dog takes Vetmedin. Is 1.25mg dose correct? Side effects?
That is a proper dose of Vetmedin, yes. This drug is used to improve heart function and will not cause fluid in the lungs or abdomen, however, congestive heart failure will cause fluid in the lungs or abdomen. If there is concern that he is in congestive heart failure, additional medication-- Lasix (also called furosemide) would be needed, which is a diuretic medication. Vetmedin is safe to give with gabapentin and Rimadyl. It will not cause pancreatitis. Thank you for asking Petco Pet Education Center, formerly Petcoach!

Is Vetmedin making my dog's heart bigger or causing an overdose?
Vetmedin does not increase the heart size. Since I don't know how much your dog weighs I cannot comment on the dose. If you would like to post again with her weight then we can maybe help you determine if that is an overdose. You can always talk to your vet about changing the medication - I would not change anything without speaking to them first. Is she taking any other medications for CHF like furosemide or enalapril? If so, the enalapril is most likely causing the increase in heart rate after administration. None of the medications however, will cause the hear to enlarge. The heart is enlarging due to the normal course of the disease. The medications only help to support the heart - they will not stop the progression of the disease. Hope this helps. Best wishes.
