Best chew toy for GSD’s
Size: Medium, Style: Bone, Product Packaging: Standard Packaging, Size: Medium, Style: Bone, Product Packaging: Standard Packaging
One of my dogs has chewed through most chew toys for aggressive chewers with ease. This toy not only is still in one piece but still her favorite toy. We’ve gotten her many Kong toys and this one has definitely lasted the longest. She’s been chomping on it for about 2 years now and looks mostly whole.

Received the product very quickly. Product was well packaged and was exactly what I ordered. This product is NOT for excessive chewers. My doodle had a piece bit off in 15 minutes, and I had to trash the product😞

Perfect for light/moderate chewers
Size: Extra Small, Color: Blue, Size: Extra Small, Color: Blue
My dog wouldn’t stop biting on the toddlers plastic dinosaur toys, so I got him this because it’s similar to plastic. But not hard enough to where it could damage his gums, also not soft enough to break apart. It’s perfect and he’s very happy with it. My dog is 6 LB toy poodle for reference, I would say this is suitable for small dogs. I saw reviews saying that their dog absolutely destroyed it immediately, but then in the review pictures their dogs were baby bulldogs/german shepards! This isn’t meant for breeds like that, but if you have a smaller dog with smaller teeth then this is ideal.
