Looking for a recommendation on a chew toy that can't be destroyed in 30 minutes. My Goldendoodle (adult and about 65lbs) loves to chew but she can destroy most rubber chew toys with no problem. The Kong I gave her for Christmas lasted about 30 minutes! I'm looking at Goughnuts chew toys -- does anyone have any feedback on this brand? Is there another brand or another type toy you'd recommend? TIA!
