My brother was just saying he heard on a radio station that a new study was done on chihuahuas. They checked the DNA and found no actual canine DNA. Apparently, they are really rodents. ????I don't know anything more about it, just thought I'd share. If I'm wrong, oops.
Yeah, that was the same article that said alot of dogs have no dog DNA like yorkies (pigeons). LOL! It was a pretty funny article..it written like a serious science report so I'm sure alot of people have taken it seriously.
