Sometimes shelters don't check the chip as they should, plus not all microchip readers are universal. Microchips can also migrate under the skin-- I know of one dog whose chip wound up halfway down her side. They're great things, but they aren't foolproof.
Wish I was in TX to help the little guy. :/
