@dcerot Seconding this! They’re called Kong Extreme for aggressive chewers. My brother got the medium sized bone for his dog when he was a pup & they still have it almost 10 years later. They can be hard to find sometimes though. Pretty sure Amazon sells some of these toys.
@blackzeppelin The only thing that has worked for us is Kong Toys (can't be one of the small ones because he will still kill those) and these super bionic urban sticks. The sticks he still manages to rip in half, but then he has to nubs from them that last forever.
@blackzeppelin After my dachshund got unwell twice from natural treats and my vet mentioned ecoli being found on them besides other bugs and bacteria they persuaded me to give them a miss and get better with kongs. Freezing is the game changer as anything with a liquid content will freeze and then it takes twice as long to get out and to eat
