Glad the results were favourable :)
Of course no doubt your vet has explained that a "poo test" wouldn't reveal EPI and a few days on a different diet would not alter the condition of his coat.
Hopefully whatever has been ailing him is on the mend but in view of your previous posts, his breed and his age I'd still invest the small sum required to have the TLI test done.
Good luck with him,
regards, Teri
