We got this for our grand-dog, a tiny Havanese! It's a great size for her. It was challenging to find things she could carry around with her tiny mouth when she was a puppy and we liked the added bonus of her pulling them out of the skull. Another activity in her day.... It was the perfect seasonal item to add to the toy box. It's her favorite thing to carry around. The squeakers are still going strong. It got a little crusty after she played with them for a while, but they washed great! Still holding up! Would recommend.

My little dog's favorite toy

Color: Skull With Spiders

These spiders are small and not for big dogs. But my little one loves them so much and it is hard to find good durable toys small enough for her. I love these spiders so much I wish I could buy just the spiders. the ones they sell alone are too big for her. If some one from the company could help a sister out on how to buy the spiders without the skull I would be for ever grateful.

Small, below-average hide and seek-toy

Color: Skull With Spiders

This toy is not as large nor as well-made as the 6 other hide and seek-toys our dog has. The small size of the skull makes the dog disinterested in it. For the size, the price should be half what it is.
