I have had great success with Nylabones in the past. However, my 2 APBT want nothing to do with this style. I purchased 2 of these several months ago and they still look brand new in their toy bin. I think the reason they do not prefer this style is because they are not as solid as their other Nylabones.
I stumbled upon Dura Chew Plus in the Souper size for my almost 2 year old Golden/Yellow Lab mix, Murphy. I think he hears me talk about the rating of toys, and makes it his goal to be more destructible than the maker thinks possible. This bone lasted about 3 months! This "puppy" mamma couldn't have been happier! Murphy plays with the Nylabone toys for hours, and likes to share them with me whenever he thinks I look bored. I can't wait to try all of the other Nylabone options for Mr. Murphy! If you've got a beyond mega chewer, I would highly recommend giving this a shot!
