yep, the kong toys are about the toughest. Just got my lab a new toy sat night(not kong) It was destroyed by Sunday morning. My Lab is now 2 years old now, but I have to say, she has been very good about not chewing me out of house and home. My last lab chewed everything from patio furniture, swingsets,truck brake lines, ac. thermostat lines,to tractor seats,hydraulic hoses, light switches and everything in between. That was all before she was 2. Another good chew toy that is cheap too, is an empty gatorade or water bottle. Water bottle makes a nice crunchy sound when they chew it. Glad this dog loves chew toys, dont know if I could afford another one like last one.
