Cutting his food down that far can malnourish him......regulating food is just one facet of losing weight. And that could lead to lethargy. But I think hypothyroidism is a strong possibility, so I'm glad you've scheduled the testing.

I agree he needs a full blood panel, otherwise, if it's not thyroid, you'll have to take him back for it. Might as well have it all done now.

Let us know what they say.
