Ancient Pet Picture?

Is it just me or does this look like a Native American decided to immortalize his favourite dog in stone? Proof that they had pets? I think it just might be so myself.

I took this one in Moab (I think) and I almost entered it into the fair, but it did not make the final cut this year. It is less than a year old, so I can still use it next year if I want to. It is one of those petroglyphs that looks familiar, but does not seem to be of a hunting scene or of something abstract. That is one of the reasons I like it so much.
