I bought this because my dogs do not want “gentle play.” They want something they can really grab, shake, and try to win. This has been a great tug toy for that. The material feels thick, the stitching has held up, and it has enough grip that I can keep control without it slipping. It is also easy to rinse off after backyard dirt and dog drool. This is the kind of toy that actually gets used instead of ending up ignored in the corner.

My Scottie loves it!
This item arrived in a sealed plastic bag to protect it during shipping. My Scottish Terrier LOVES this toy! She's the queen of tug-o-war, and the more she can fling a toy around, the better, which makes this one a winner in her mind. It's very comfy for us to hold onto while she tries her best to yank our arm off with it, since she can really get a good grip on her side. My Westie wasn't impressed, but she's not really a "toy" dog, to begin with. So far, it has withstood the might of the Scottish Terrier alligator jaws, despite her trying her best to destroy it, so hopefully she'll be able to enjoy it for awhile. Great quality, great durability, made in the USA, and for a reasonable price, it's a winner in our house!

Our dogs love it. A great, indestructible, chewing experience.
Our dogs love playing with this wagalicious tuggfinity toy. In my pic you can see that they fell asleep playing with it. They chased each other around the house with it and played tug a war with it until they exhausted themselves so I’d say this is a huge hit with our fur baby’s. At 9”x7” it’s a perfect size for our big dogs. The material it’s made from (TPR) it super tough, durable and has a bit of flexibility to it and they can sink their teeth into it and tug a war with it without it getting chew marks or falling apart. It gives them something to chew in that’s not hard but is soft enough to give them great chew satisfaction. It’s a bit heavy which is good for my big dogs too because its weight keeps them active. Non toxic as well. I’d say this is a great value and because they love it so much then I love it too.
