My dog has hypothyroidism and is panting. Is it the medication?

I’m sorry to hear that Chloe isn’t feeling herself. Is it possible that she received a Double dose of her thyroid medication this morning? Over medication with thyroid medication can cause these symptoms. Otherwise those can all be symptoms of discomfort. If her behavior continues then I would encourage you to have her evaluated by a veterinarian soon. Sometimes abdominal pain or back pain can cause those symptoms and can be hard to identify without an examination. Best of luck and I hope she improves soon. Thank you for using Pet Coach.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Coco. Poor girl! It could be she is sick, may have injured herself, or this could be a side effect of her levothyroxine. Without seeing her in person, I can't say for certain. I'd have her seen by a vet now to be safe. Best of luck.

The only way to know if this is related is to have the thyroid level checked again. I recommend to call your veterinarian and let them know what you are seeing. They will advise on how much medication to give and when to test. The only way to know if Glanni truly has thyroid disease is to stop all medication for at least 2 weeks. Then test a thyroid panel that includes the Total T4, the Free T4 by equilibrium dialysis and the Thyroid stimulating Hormone. This will give you a complete and accurate idea of his thyroid function. I do not advise to make any changes to the medication with out first speaking with your regular veterinarian. Also keep in mind that the behavior could be coincidental and related to something else entirely. Best of luck.

I recommend to have Tommy’s thyroid level rechecked. These are not normal signs from the medication and could inidicate that the thyroid level is now too high or it could be unrelated. That’s why you need to know what his levels are while on the medication. Have the blood sample drawn 4-6 hours after he takes the medication. Best of luck and please feel free to post any additional questions.

Hi. Unfortunately, to determine the cause, she would need a full work up. Breathing problems are not typical of hypothyroidism. Panting can occur with Cushings or hypothyroidism, but not respiratory raspy/labored breathing. I would have them do chest radiographs as soon as possible.

I'm not sure if you mean that she is already on DES (low dose estrogen) when you say "HRT"[hormone replacement therapy]. If she is already on DES, adding the mediation Proin may help with her wetting herself at night.

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/
