just loved that song by Bocephus when it first came out, and it still rings true [maybe even more so] today !
and the mexican dog song was great !
as my wife and i have have been caretakers of several of those little creatures over the years, some can be real ba$tards, but most are so loving it borders on being criminal.
it boils down to the people bringing them up correctly, and socializing them at a very early age, plus the right training regimen.
it reminds me of a dog my one cousin's girlfriend had at the time.
that doggy didn't like cousin "wonderful" [name is a story for another time], but it wasn't a chihuahua.
anyway, one time after an overnight stay, cousin "wonderful" rolled out of bed and stepped into his shoes, only to find the doggy had blessed him with "presents" in both shoes !
the relationship didn't last very long after that..........
