Received broken unit
Size: Dog Rope Toy - M, Size: Dog Rope Toy - M
One of the two main strands of the toy are totally ripped apart and frayed before ever being used. Will fall apart very quickly, returning.

Very good squeaker sound and well made
Style: Hedgehog dog toys
My spaniels are so accustomed to this very specific squeak, that they come running no matter how far they’ve run. Unfortunately it’s bulky to carry in my pockets so I wish I trained them (trained? That’s a stretch!) with a different, much smaller, squeaker but so far they’ve held up really well and Max now uses it as a small little head rest. Very cute.

Perfect for heavy chewers
Style: Hedgehog dog toys
These toys are so impressive! We purchased them as a gift for someone with a very aggressive chewer that LOVES stuffed animals but then makes a huge mess with all of the fluff. It’s a small to medium size dog. These toys were a great size for him and one little hedgehog lasted a whole entire week before it got its first hole chewed into it. This is outstanding quality as many other plush toys that are supposed to be durable last about 5-10 minutes for him. The fact that the hedgehog squeaks keeps his attention and then when the hedgehog is chewed up he has a cute sensory ball to play with instead of making a stuffing mess. Absolutely great product.

Highly recommended!!!
Style: Hedgehog dog toys, Style: Hedgehog dog toys
Best plush ever!!! My boys absolutely love it; they normally destroy plushies within 5 minutes but they’ve both been carrying theirs around all day. The lack of stuffing means I won’t have an explosion to clean up, and the squeaker is huge (it’s the main bulk of the body) so I don’t have to worry about them accidentally swallowing it. Great size, well made, great texture/materials.

Sturdy and cleans teeth!
Style: Hedgehog dog toys
My chihuahua and I play catch with this hedgehog chewy and it's perfect! It's very slightly large for him but he likes carrying it, can do so well, and it cleans his teeth! Plus the large squeaky insight gets him pretty excited. I appreciate the slightly lower tone. Also, the items arrived NOT soaked in fragrance like so many pet products. Very grateful. 5 stars!
