Great stimulation for active chewers!
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
"Long lasting chews" never make it past 5 minutes in mouth of my Golden Retriever, but this one will! He immediately started chewing on it and barely made a dent. Love that this product is safe, clean, and enjoyable for my boy. Highly recommend!

100% Puppy-Approved
Flavor Name: Beef, Size: Small
My little fur baby absolutely LOVES this!! ❤️ He immediately got the zoomies when I gave it to him. 🤣 It's his new favorite chew toy and keeps him occupied for long spans of time while inside or outside of his crate. Very durable, smells pleasant, and is the perfect size for my small puppy (he is currently 10 lbs and I got him the small one). Previous chew toys that I purchased were too large/heavy for him to pick up, but this one is lightweight and perfect! I highly recommend! 🙌🏾

Not destuctable
Flavor Name: Peanut Butter, Size: Medium
This is the first toy that none of my dogs have destroyed. It's still going strong and they love carrying it around and gnawing on it every day. The material is durable and the product is the perfect size. I will buy more soon.

Best Dog Bone
Flavor Name: Beef, Size: Large
This is one of the best bones I've seen and I have always lived with dogs. The shape makes it so ergonomic for the dog, both of mine hold the bone down with both paws then chew the part standing up. One of my dogs was able to enjoy this while wearing a cone after surgery, supporting her natural behavior and keeping her busy. These are great for our 11 month old puppy because he was struggling to figure out how to brace the bone without it rubbing his paws, so was bracing on furniture and getting in trouble. Now he can hold the T part easily and doesn't need to use other objects he shouldn't chew by accident. They are durable, too. I got these about 2 months ago and they are barely worn with a rotty/pit/Shepard mix male puppy. If you know dogs, you know that means this is a solid durable bone! I will for sure keep these on hand for years as they are a preferred chew in my house!
