Our dogs hurt their mouths chewing these bones
Color: Purple & Blue
I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….
Color: Purple & Blue
I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…

Durable but losses interest
Color: Purple & Blue
My dog is an aggressive chewer. She was interested in this toy while it was new, but soon after lost interest. Good news is although it took a beating it did not break or splinter. If soppy toys are disposable in your house, give it a try.

Great for treats
Size: Small
Great for chewers. Tough medium size toy, treat toy, busy entertainment for all dogs. Dry, moist or squeeze food can be placed in the end and sides. My dog loves.

My dogs are smiling!
Size: Small
I have 3 small dogs (ranging from about 10 lbs - 13 lbs). This dental toy was the perfect size. My dogs love it (with or without treats). It is durable, even after lots of chewing. I had bought another brand of the same type of toy and they bit off pieces in the first week. It really has made a difference in their teeth cleanliness and their breath is even fresher. Overall great value and my dogs love it!
