Mehr Animal in Harvest Moon: A Wonderful life?

Du can't do anything to get them. I don't know what anyone told Du but it seems there is no way to get any animal other than farm Tiere (like chickens and cows), a dog, cat, and a horse. If Du befriend Lumina's grandmother, Du can get one of her Katzen eventually; and at some point Takakura will bring Du a horse. Other than that there are no other animals.

For instance, the little animal sometimes near the dig site with a bandanna around its neck. Du can't keep it, I'm pretty sure. I've tried so many ways. I can keep checking though.

Edit: Okay, I found a really trustable site/person (link) and you'll see it says Du will never recieve that chihuahua (the bandanna animal). And it doesn't talk about the others. I assume they'd know if it was true. You'll just have to assume that Du can't get any other animals.
