Dog likes some
Size: Extra Small, Color: Blue
Puppy will chew on this but not favorite. Over time it gets sharp pieces and dog could ingest. Not sure how safe for a small dog. Affordable but not long lasting.

Works great for my goldendoodle. It’s held up well to two dogs and lots of playing. It’s nice and large and has held up outdoors in Michigan winters
