TIP #1: IT'S NOT HELPFUL
The term dominance is a label, not a solution. What’s more, it sets up a conflict. If I believe my dog to be dominant it follows that I must make him submit to me. This often results in an ongoing battle of will that is unpleasant for both of us.
TIP #2: VARIETY IS THE SPICE OF LIFE
Dogs have distinct preferences when it comes to toys, so it's worth doing a bit of sleuthing to figure out what hooks a particular dog. Some are never happier than when they get to dissect a stuffed toy; others can spend hours entertaining themselves with a rope toy. Get an assortment and switch them out each day so the dog doesn't have time to get bored. Of course, you want to make sure you use safe toys so your dog does not ingest parts and pieces of his toys.
