Quite small.
These were way smaller than I imagined based on the photos. Those were obviously ai generated photos that don’t even look like the product at times. They are pretty flimsy and I wouldn’t buy again. My dog will tear this apart in 2 min. But it’s a good size to throw around I guess or maybe for a much smaller dog that doesn’t also want to chew. 3 stars because we will get some play out of them and there’s 2. Just know what you are getting

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!

80lb Dog Goes Wild Over This Pulpo
My dog goes wild over this toy. The key difference between this and other octopus chew and rip toys is that this has a head horn, crinkle legs, and a squeaker in every limb. It makes it so much fun to play with him. After he destroys the sounds, he parades it around for his victory show.
