My Portuguese Water Dog received the Bumi as a gift when he was about 3 months old. He's now almost 9 months old and today we had the sad task of removing his favourite toy from him as he'd finally destroyed it. He's a real "power chewer" and this toy lasted fairly well until recently. He loved the shape as it made it easy to carry around and get a good grip on for chewing.
Unfortunately I don't have a receipt so I'm not sure I can get a replacement Bumi. Maybe I'll try the Hurley next.
