Purrley, you know what I noticed regarding feeding time for chihuahuas? That as long as we feed them "dry" dog food, they all eat the same way (grab 2 or 3 pieces, run and hide them, come back to the bowl & start again). They will not stay still long enough to eat what you feed them, but will prefer to eat on and off during the day. That doesn't seem to happen with regular dog food, just the dry type.

When I first got Tobi, I fed him regular dog food for a while, twice a day (6am & 7pm) and THAT he would eat right away, but it's not that way with the dry kind.
