I AGREE. I would not rule out hypothyroid and would keep him on the meds to see how he does. If it the meds work, IT DOESN'T MATTER WHAT THE NUMBERS SAY!!!!!
Well, it DOES matter what the numbers say, to a point.
I could give any healthy dog a supplement of soloxine and probably see improvement in hair growth, stamina... because that's what the drug does. But why give a dog not hypothyroid something it doesn't need?
Bauer was diagnosed hypothyroid, and ended up dying shortly after of hemangiosarcoma. His numbers weren't super low, but we saw what we thought were some 'symptoms' - lethargy, etc. I can't help but think now that the low thyroid was only a symptom of the cancer - and while the soloxine made him feel bettern on some counts, it did nothing for the ACTUAL problem. Had we really paid attention to his numbers, instead of finding something that worked for some symptoms, we might have dug a little deeper and found the real cause.
What I'm saying is that soloxine will cause certain results that will make people think it is "working". But that's NOT a real indication that the dog needs the medication in all cases. Which is why hypothyroidism is so difficult to diagnose and treat.
I'd say in Monty's case, given everything, there's a good chance he is hypothyroid, but it always helps to rule out any other possibility.
Great reply and I couldn't agree more. The numbers really do matter!
Here is what makes this a tough case.
Monty does have low thyroid levels, however not so low that they couldn't be in line with what is normal for a Greyhound. Also, his TSH is normal and his cholesterol (not listed above) was normal. A high percentage of dogs that are hypothyroid will have both an elevated TSH and cholesterol level. If I was only given this thyroid result with no history I would say not hypothyroid. The tough part is that not every dog that is hypothyroid will have an elevated TSH or cholesterol level. So although some Greyhounds may have "normal" levels compatible with Monty's numbers... what if Monty's normal levels are actually in the normal range for other dogs and now they are low because of hypothyroidism? Several of his signs COULD be compatible with hypothyroidism although as noted above maybe they are related to something else. This is where things get confusing... how do you know? Well, Monty has already seen teh dermatologist which is the most logical next step. If the derm vet says it doesn't look like hypothyroidism then I would pursue testing recommended by the derm vet (likely skin biopsy/culture). If the derm vet says a trial of soloxine is indicated... then I'd likely pursue that as a next step.
Clear as mud, right?
It's what makes "long distance" diagnosis very tough, I guess.
