    Solid dog toys HOWEVER...
    Size: 5 Pack
    Got these toys for our collie-retriever. He loves them and plays with them a lot and will even get them out in the middle of the night to play with them. Since there's no stuffing you can't throw them very far but they are good for tug-of-war and really soft. The one downside, while they techically are durable and hold up to rigorous chewing, they are not impervious as our little man finally disembowled Mr. Lion after a few months of playing with him. (Serated the lining with his teeth.) Still highly recommend.

    Nice but not durable for Dobermans
    Size: 5 Pack, Size: 5 Pack
    They are cute and I like that there is no stuffing. But they are definitely not for large Dobermans. They ripped the head off within 10 minutes of playing. Which I expected be a no toy lasts longer than 30 minutes.

    worth the price !
    Size: 5 Pack, Size: 5 Pack
    Best toys for our livestock puppies since they have been getting into our outdoor things which isn’t their faults but i figure I would get these small squeaky animals toys and they are obsessed and love playing tug a war with them! They’re super soft, the quality is amazing cause these puppies are tough chew monsters, love the squeaky sound it makes and the patting are suitable as well! Definitely recommend this especially for the price and how fast shipping was !

    Not very durable
    Size: 5 Pack
    They’re a great toy for the dog. However, if the dog is bigger, they are very easily destroyed.
