Stuffed with Plastic
Color: Orange & Blue
So these are super cute and they have crinkle sounds and a squeaker, but these would not be suitable for chewers. The have plastic stuffing in the legs and my dog almost choked on it...so I just have to tell you that these may be ok for smaller dogs but mine is 30 pounds and he ripped through it and started eating the plastic crinkle stuffing.

Love the look, durability and color
Great toys. My pups loved them. They are sturdy and ADORABLE! I loved that there was a pull rope on one side and that they did not fall apart on the first chew. The size is great for my big lab mix and my smaller pup. Great value. Would buy again.

Great tug-of-war toy
My golden retriever loves playing tug-of-war so this is the perfect toy for us. We’ve already played several spirited games (he has won all of them, by the way) and the toy is still intact.
Great price for two toys!

Good choice for medium size dogs
My friend’s two dogs loved these toys. They got the tug-of-war part immediately! Not real loud which is a plus. Seem pretty sturdy!!!
