Busy bone
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves these!! Great busy bone! And they can hold it with her paws really well. It does kill your foot if you step on it barefoot in the middle of the night. This is a picture of the bone after 7months.

My Dog Loves this!
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves her Nubbies! My Dog chews her Nubbie every morning after she has her breakfast. She sometimes wants my husband or I to hold it for her while she chews on it. I think it is really good for her teeth and gums. These last a few months for our dog who chews it every morning. After a few months the edges get a little rough from all the chewing so I throw it out and replace with a new one. These are very reasonably priced, so I always have a fresh one ready to go. She gets very excited when we get a new one out of the package..

Very durable!
Color: Blue T-Bone, Size: 1 Count
Great product! Dogs love it and very durable. I had been buying the nylon bones in pack of 3, but my 2 dogs would chew them up in no time, and I was buying the aggressive chewer bones. Bought 2 of these, dogs loved it, so I bought another one. Have had these for about 2- 2 1/2 months and still holding up just fine. And the price is great! Would definitely recommend!
