My dog Lisen loves to eat, anywhere - anytime! She is always up for having a little snack or treat, even on our walks. And when I do not give her one, well then she tries to find something edible outside. But if she does find something to eat, she at least usually asks for my permission before she eats it. And she asks me by looking up at me with her big brown eyes and licking her mouth. However there have been a few occasions when Lisen has just gone for it and grabbed whatever she has found without asking. But those are rare occasions, and I usually manage to grab whatever she has found out of her mouth before she swallows it. Hehe.
In any case, Lisen sure seem to think quite a lot about eating during a day. At least that is the impression I get from her. :p
