My wife and I are sitting watching television and a travel Texas commercial comes on. After it was over my wife said "Texas" and my dog who was sitting between us started to growl.
I said "Texas" and she barked and went into her chase mode looking around and growling. I said you don't like "Texas" and she barked again.
Come to figure that she really does like Texas but doesn't like "cats". She was hearing "cats" while we were saying Texas. I guess the "x" and the "s" sounded like the "catssss" that we tell her when it's time to chase a neighbor's cat out of our garden.
