DO NOT BUY THIS TOY FOR A DOG
Style: Hedgehog
I purchased this toy for my Mothers 11 pound female 10 years old rescue dog. Under 1 hour the dog chewed off all the feet, the nose, and then started to pull off the fur. We took it away. Dangerous!!! The description list for Aggressive Chewers it is not!!!

Very High-Quality Hedgehog Dog Toy That’s Bigger Than Expected
Style: Hedgehog
I am SO happy with this -- it's a nice surprise to get a dog toy that is this nice quality-wise! This plush toy is well-made and much larger than I thought it would be. The stitching is solid, and the material holds up to rough chewing. My dog’s been playing with it daily and it still looks good. The squeaker’s not too loud, and the soft texture makes it perfect for tugging or tossing.

Very Soft Toy
Style: Hedgehog
This stuffed hedgehog is very soft and has a really nice squeaker in it. I can already tell that it will absolutely not hold up to an aggressive chewer, but it will be fun for a day or two for my pup. It would probably be way better as a giant toy for a tiny dog, but it was so cute that I couldn't resist for my husky mix.

One of my dog’s favorite toys.
This is one of my dog’s favorite toys. She loves figuring out how to pull the crinkly part out of the rubber tube, and she loves chewing on the spiky rubbery tube.
I have to replace this toy often because my dog also likes to pull pieces of rubber off of the tube. She doesn’t ingest the rubber; she just loves the act of pulling it all apart.
I am still giving this toy 5 stars because my dog loves this toy and it keeps her busy.

Not a durable toy.
This only lasted a few minutes before it was destroyed by our dog. Not made well for chewing.
