Sorry, but the last time I checked there was no credible evidence that "dogal" was ever used in Mexican or any other kind of Spanish to mean "dogie."

The supposed derivation seems to be based on nothing but a superficial resemblance between the two words and a connection with ropes. This is undoubtedly coincidental

What is required is some Spanish examples of "dogal" that plainly mean "dogie."

When I looked into this a few years ago, I came up with nothing.
