AmStaf/Lab loves this product. I am still concerned about him ingesting the sharp little pieces he gnaws off, but he seems OK after three months of using these. Tried the Nylabone natural/wild products but they are not usable as a "chew" and disappear within minutes, nay seconds! -So here I am back to the "strong chew" wishbone product which makes my dog happy and keeps him busy not eating my shoes. (Be warned though, these are worse than Legos if accidentally stepped on!)

Perfect for small dog that likes to chew

Size: Small, Color: Textured Ring

Just got this today (small size for my 15 lb dog) and she loves it. Perfect size for her small mouth and teeth. Keeps her busy and even tires her out and rests a while, Between this type of dog toys and ones that squeak she is having a great time

Great purchase!

Color: Red, Color: Red

I have 3 very different dogs, a Doberman, a rat terrier, and a German short hair - Great Pyrenees mix. They all LOVE these durable chew toys. I will definitely be purchasing more when the time comes. I wouldn’t need more due to durability but my rat terrier is an expert toy hider! 😅
