Large adult aggressive chewer? No. Puppy? Yes
Pattern Name: Classic Squeaky Tug
My large adult dog who is an aggressive chewer got this toy in pieces within minutes, BUT this is a great toy for a lighter touched dog. When I got my newest addition (Malinois mix puppy. Pls thoughts and prayers for me), this toy came to mind because she loves chewing and she’s only 11 weeks old! She needed an interesting toy that is sturdy and won’t hurt her teeth or gums, but is still interesting (the rope piece and the squeaker). She’s not nearly as rough of a chewer as my older guy YET. But when she gets bigger, she will more than likely destroy this. She is almost 20lbs at 11 weeks right now, so I will update if she does destroy it. Long story short: Not good for large aggressive chewers, good for aggressive chewers on the smaller side (maybe 15-30lbs)

Pattern Name: Classic Squeaky Tug
Love, LOVE, LOOOVVVEEE this toy!! Finally, an actual indestructable toy for my super chewer!! As others have said, the little rope thing came off in less than an hour, LOL. But the 'Corn cob' is great!! My baby LOVES this thing and chews on it constantly and it shows no sign of wear!! I am optmistic that it will actually last more than a month.
