William Cramer 3 My dogs are not interested in these at all. Can you imagine a dog not interested in a treat?!These are like hard rubber. I tried to break one in half to hopefully give the dogs more smell and taste but it would not break no matter how many times I bent it back and forth. I gave longevity 5 stars because I don't even see a dog tearing these up, that is if they were interested in it. These are advertised as tarter removing treats so I thought that they would be consumable. In the trash they will go...
