My dog ate Euthyrox meant for another dog. Should I worry about him?

Since it has been several hours, inducing vomiting will not help. Dogs take higher doses of thyroid medications than humans do, so it is likely that Roxy will be fine. He may develop some stomach upset. Monitor for rapid heart rate, panting and restlessness or hyperactivity. These are symptoms that should be addressed by your veterinarian or at the nearest veterinary ER. You can also contact the Pet Poison Helpline ( https://www.petpoisonhelpline.com/ ). They are staffed by toxicologists who have more detailed information. There is a fee for the call. https://www.petpoisonhelpline.com/poison/thyroid-medications/

Most Levothyroxine tablets come in 0.1-0.9mg dosages, so I am not sure why your pet is on a full 5mg dosage. If this is not a typo, then this is a pretty hefty dosage for a cat to receive if she surely got 2.5mg's. However, severe life threatening symptoms from a single overdose are less likely than with chronic overdosing. Some signs you may see are: Vomiting, diarrhea, hyperactivity to lethargy, hypertension, tachycardia, tachypnea, dyspnea, and abnormal pupillary light reflexes. It can take 1-9 hrs for absorption to occur. Then the drug should be mostly out of her system 12-24 hrs. In most cases this is not an emergency situation, but you can see the symptoms I mentioned above, which should be treated with supportive care through your vet. This is a tough one indeed, but it is likely that Kilala will be ok, since I assume that the dosage you gave has to be incorrect based on the typical dosage that dogs receive (between 0.1-0.9mg). I hope that everything works out well for your pet Kilala. Best wishes and take care!

A single dose of this size of Vetoryl will likely pose no serious risk of toxicity. Monitor for lethargy, vomiting, diarrhea or loss of appetite. See your veterinarian if any of these symptoms develop.

Overdosage of any thyroid drug may produce the signs and symptoms of thyrotoxicosis including, but not limited to: polydipsia, polyuria, polyphagia, reduced heat tolerance and hyperactivity or personality change. if she is experiencing any of those- take her to your vet, if not she should be fine.

That should not cause any damage or severe toxic effect. I would just monitor him at this stage but I would definitively recommend a veterinary check up if you notice diarrhoea, vomiting, lethargy or inappetence. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi, The levels of concern for estrogen are dosages > 1mg/kg. In this case as I can understand from your question the dog ingested 2 tablets of 2 mg estradiol which is a total of 4 mg estradiol. If we devide the 4 mg by the dog weight 25 kg we get a dose of 0.16 mg/kg ingested which is much lower level than 1 mg/kg. So if these are the right details it is not at the toxic range (of bone marrow suppression). Just keep it in cupboard or a drawer away from Loli.

While not ideal, not getting thyroid medication for 10 days should have no lasting negative effects on your dog. A quick call to your vet would be recommended for confirmation. He or she may want to see Morris and possibly submit blood work to check thyroid levels.
