Cute and fun!
Color: Blue, Color: Blue
This was exactly as described! The head has a squeaky and the legs crinkle. I have a small dog who does not destroy her toys so I think this will last a long time. So far—she loves it!!

My dog loves it. It's really crunky. nicely made.

My Yorkie’s new favorite toy
Color: Orange
This octopus toy was an instant hit with my Yorkie! The size is perfect for a small dog, and he loves carrying it around the house and tossing it in the air. I really appreciate that it has no stuffing, which means less mess if he gets a little too enthusiastic with his playtime.
The material feels durable, and the toy has held up well to daily play. It’s soft enough for cuddling but sturdy enough for tugging and chewing. The squeakers keep him entertained and engaged, and he always gets excited when I bring it out.
Overall, this is a fun, well-made toy that keeps my Yorkie happy and occupied. I would definitely buy it again.

Octopus dog toy
Color: Blue
My chihuahua loved it but didn’t last very long. Not very durable and was very small. He was able to get the plastic material out fairly quickly.
