My dog (female) has this chewy snack thing, it's like a bone since it's hard and good to chew on and it has this brown stuff in in so I guess that's the snack inside. Anyway, she picks it up and goes somewhere and puts it somewhere and she just sits there in front of it, and when I try to pick it up she bites me and growls at me. So I leave her alone and after like a min, she leaves it and when I take it she doesn't seem to care anymore and she just looks at me. And it goes over and over again. And she's not even playing with it!

I mean if it's her property, why does she leave it alone after a while
