[Gracie2006]

Here's the deal. I don't have skin kids, so maybe I don't understand sibling rivalry. Can someone please explain something to me. I have two Yorkies, Gracie is the older, Holly is the puppy. I can have 3 of the same toy or chew, give them each one (both identical), and 100% of the time Holly will steal the one that Gracie has. She won't just steal Gracie's, she will hoard all of them into a nice little stack all of her own. Is this just rude puppy behavior that she will out grow? Poor Gracie is getting really miffed at her little sister (no acting out but I can tell she is frustrated).
