Very cute! My dog loves it!
You cannot beat the price of this donut dog toy and it includes two of them! I opened these up and my dog wanted to play with it right away. They are smallish, probably about the size of a regular donut. It might look a little small compared to my dog but he is 125lbs. These little donuts even have squeakers in them.
Is your dog going to be able to rip these apart… yes. I never expected him to not be able to rip these up. My dog first likes to give it nib nibs and then he will eventually rip it up. You will not find a better dog toy for the price that these are selling for on Amazon.
Plus it is adorable seeing your dog walking around with a donut in his mouth!

The indestructible sharkie
High and low have I searched when quite by accident I just happened upon the indestructible sharkie. We are fast approaching the 24 hour mark and sharkie is still with us. He has thus far resisted the incredibly strong, outrageously aggressive and persistent chewing of my Bernese mountain dog. Most don’t make it 20 min, so a whole day?!? Miracle!!! Not in love with the incessant squeaking that has followed me, but then again… that’s because this is actually not simply a review but a love story between a dog and his shark toy. Where others have failed, this one has endured. My water fearing dog has an obsession with shark shaped toys so while it would be nice to see a different character, truth is… I’ll be buying more sharkies. A lot of sharkies. Yard sharkie. Work sharkie. Maybe not house sharkie… but you get the point.

Great for tough chewers
I have purchased this twice! My dog absolutely loves it! He is a pit-bull Shepard mix and an extremely tough chewer. The first toy lasted almost a year of him chewing on it daily
