My lady moved in a few weeks ago, and brought with her a nomtastic Labrador (Sen). I already had a nomrific American Bulldog puppy (Samson). Within about 3 days, all of Samson's previous toys were destroyed. Needless to say, they get along fantastic (I can't tell who loves who more, these dogs are inseparable by will and its only been a few weeks), and they LOVE playing tug.
To the Bumi! The only toys that lived through the first wake of 75lb bully pup and 65lb lab spaz destruction, were the kongs. I won't knock the kong, for a single dog to chew on. They're great for that, but for two dogs pulling on the same toys, this Bumi has been incredible. They've probably had it 2-3 weeks now, with a good 2-3 hours per day (combined play times) of just 'going at it' trying to play keep-away.
I wish I could post a picture, but we threw it in the dishwasher 2 nights ago, and the thing looks as new as when we bought it. I don't know a better way to give this product the props it deserves, without telling the story the way it went down :)
