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.

It's good

My dog doesn't like it and he does typically like these but it is really nice quality and I like the shape and design so definitely try it because of the price

Great toy. Definitely worth it.
Pattern Name: Classic Squeaky Tug, Pattern Name: Classic Squeaky Tug
This is a great toy. I bought this for my dachshund, and it's still going strong after 2.5 years. The string part came off after a few months, but that's fine. This is always her go-to toy.

Perfect so far!
Pattern Name: Classic Squeaky Tug
My dog has a habit of tearing up toys in just a few minutes, so far, this toy has lasted a few days, the rope is already showing signs of wear.
I wish there was a way to attach a new rope when this one goes...
She is a mid-sized dog with a LOT of energy, and she's very destructive, digging, chewing on things she's not supposed to, etc.
This helps with that, she can play with it for a long time, we don't have to always 'check' to see if she is tearing something up.
She loves grabbing it by the rope and swinging it around the sides of her head, it doesn't hurt her, and she LOVES this toy. Out of ALL of the toys that we have bought her, and that she loved, THIS ONE has been top dog to her. We love watching her play with it, it also wears her out and she'll then take a nap, which is always good.
Oh yeah, the size if PERFECT for a mid-sized to a large dog, I'm not sure about any smaller dogs. She can squeak the squeaker on it fine too, but not at first, she had to 'find out' how to do it on her own.
As far as chewing it into little pieces like one person has said, I can't attest to that, and I hope that is not the case.
I will return if she does end up chewing it into pieces, because she in known far and wide for that! :)
