Hello and welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Was his heart rate elevated when his vet examined him?

How elevated was the thyroid level on the bloods?
Customer: replied 2 years ago.

As far as I know his heart rate was ok although he was terrified at being at the vets I don't know what the thyroid level was in his blood at the Intitial exam the vet even said to that he didn't think there was anything wrong with his kidneys or thyroid

Thank you Rosemary,

In a situation like this, we do need to tread with care. As he doesn't appear to be hyperthyroid, I would first suggest having the vet phone the lab to confirm or recheck the results. That way we can make sure this wasn't lab error.

If the results are genuine, then we do have a few options. As long as he doesn't have a racing heart rate (which you could try taking at home by putting a hand over his heart, counting the beats for 10 seconds + then multiplying by 6. Ideally, unstressed at home it will be <180bpm) and no signs that fit, then you can monitor with a view to just rechecking the thyroid levels in 3-6 months. Of course, if he is early stage and we were to see signs start to creep in between then and now, then we'd need to consider treatment at that point.

Otherwise, I would say that if you wanted to err on the side of caution without giving medication unnecessarily, you could also consider putting him on Hill's Y/D (More Info) at this point. This is an iodine restrictive diet that is used to manage thyroid disease. It works by limiting the excess iodine that the overproductive gland would use. That means it only has enough iodine to support normal thyroid function. So, if we put Dennis on this, he would have enough iodine (and all his other nutrition needs of course) for normal function but if his thyroid is even thinking about being overproductive, then it would block that and head off any development of clinical signs. So, that would be an option as well.

I hope this information is helpful.

If you need any additional information, do not hesitate to ask!

All the best,

Dr. B.
