My dog is a 2-year old miniature dachshund who weighs about 8 lbs. Believe it or not, she is the most extreme-chewing dog I have ever owned! Perhaps she's a little unique in her jaw-stength, but she has destroyed about 85% of all the toys she's ever had, excluding classic Nylabones (which she's still chewed down to stubs).I purchased this RuffDawg - The Rock toy because reviews claimed it to be an extremely fun, durable toy that dogs love to play with. I'd agree with most of that statement - we played fetch for a very long time and my dog absolutely loved how the toy bounced all over the place. But as soon as I let her chew on it for a few minutes she had already torn a chunk off. Other reviewers have stated this as well, but the part she chewed off was on the flat "ledge" on the side. Perhaps a re-designed version of this toy would be more durable?I might keep this toy for fetch sessions only. I will not be letting her chew on it any longer, however, as the chunk she chewed off was much larger than a grain of rice (that size or smaller is okay to ingest, apparently). She went crazy the whole time were were playing fetch and I do like the toy, but I wish it was slightly more durable.On a different note - As another reviewer stated, I tried to order the "marble" pattern and instead received solid bright orange. I wish I would have received what I ordered, or got to choose the color. My dog already has several orange toys in the same type of material and I'm looking for variety for my dog to continue enjoying playtime.
