This is about doggie toys in general.
In the pack situation, dogs find their own entertainment, so a stick or a pebble can become the source of endless hours of entertainment for a young dog. The higher up in the pack that dog ranks, the more control he has over what toys he plays with, when he plays with them and when he shares them with other dogs lower down in the pack.
If a lower ranking dog tries to take his toy from him, he’ll growl, show teeth and become aggressive enough to let the interloper know who’s boss.
In the family “pack” the dog will often have a whole box-full of toys. Balls, furry things, squeaky rubber things and all sorts. If your dog believes himself to be of high enough rank in your family pack, he’ll quite happily help himself to whatever toy he wants from the box, whenever he wants it.
When he’s finished playing with it, or allowing you to share it with him, he’ll simply discard it where it falls and go off to do something else.
To really get on top of your dog in the family pack rankings, you need to change this behaviour somewhat. First up, place the box of toys out of your dog’s reach somewhere high. Then, when you want to play with a toy with your dog, you go get it. When you’re finished, take it off him and put it back in the box.
That tells him that you are the boss and you decide which toy he plays with, when he can play with it and for how long.
