TWO of my favorites are
1. A smoked beef knuckle bone or similar...it doesn't contain copious amounts of food, but it smells so good and meaty that they will chew on it for hours...IT IS THE "EVERLASTING GOBSTOPPER" of CHEW TOYS...
when your dog stops eating it, stick it in the freezer for later.
2. Bully Sticks are long brown sticks that the dog chews on and they also take a long time for the dog to get through. They are available at many petstores..sometimes they are called 'pizzle' sticks....[don't ask what they are]
The goal with a chew toy is LONGEVITY and RELIABILITY. THe chew toy should be an absolute ACE IN THE HOLE as compared to WOOD, RUGS or SHOES, which means it probably should be smelly and edible [that's what the DOG wants--they resort to shoes etc, when there isn't a better option nearby]
Your dog MAY chew on other things, but they aren't "ringers" for his attention like meaty chew bones and sticks.
