My pet is on thyroid meds. Why is he panting, drinking, not eating?

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.

Panting is not a common sign in dogs taking medication for hypothyroidism. However, I did a little digging through some veterinary databases and found some reports of dogs panting excessively with different brands/dyes in the levothyroxine medication. Panting can be a sign that Bobbie's levothyroxine dose is too high, or could be a sign of other conditions, such as heart disease, pain or anxiety. Regardless, I recommend taking her to the vet for further evaluation. They may want to recheck her thyroid blood tests to check her current levels and will want to examine her to check for other problems. I hope this helps and that all goes well!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I would have his thyroid rechecked soon. Schedule an appointment to have his T4 rechecked 4-6 hours after the pill is given. The dose may be too high causing hyperthyroid signs. Signs of too much thyroid hormone is increased thirst, urination, hunger, increased activity, weight loss. I wish you both the best!

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.

No, you shouldn't discontinue the medicine without consulting your vet but you must take her to your vet ASAP as there is obviously a problem, either the dosage needs to be adjusted or maybe she is developing a kidney disease, which is common with cats with hyperthyroidism.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! A T4 of 1.8 is normal and doesn’t indicate hyperthyroidism and it means the dose Tony is on a good dose. I wound investigate other causes of increased thirst: diabetes, liver disease, high calcium cancer, etc if his thyroid is regulated and his kidney values are normal. I hope this helps and I wish Tony the best!

I would recommend rechecking Reba's thyroid level about 4-6 hours after you give the pill. I would also check a urine sample at the same time to check for a urinary tract infection. Thank you for using Petco Pet Education Center, formerly Petcoach.
