Chico has lost some weight,he weighed about 16lb's in 2008,today he was about 14lb's.
Rocky(I still miss him
) lost weight rapidly,although he ate like a fiend and was constantly drinking,Chico does neither.
So what I'll do,I'll wait a bit and if the vet wants to do the Free T4 and the regular T4,I'll have it done.
When he had all the test when they were both sick,my regular vet saw no problem with his T4 number.
