Looking for some insight into why my dog does this: We got an adult dog from the pound a couple of years ago and she does a really bizarre thing. Whenever we will call her over to play or rub ears, she will dance around for a while and go searching for one of her chew toys. Once she finds one, she will come over to us, but she will rarely come over to us without holding something in her mouth. She doesn't want to play tug with it and rarely "presents" it to us as a present (she does do that occasionally) but usually just requires something in her mouth when we call her over. Any ideas on what's up?
