Our 4 month old golden retriever loves chewing the Tizi as he is loosing and growing a lot of teeth right now.
The legs on the tizi are just right size for him to chew. I was surprised to find that about the inch from the end of the leg where he chews the most, there are punctures and cracks. The Tizi is still in tact though.
The Tux that we bought at doggie day-care is a little too big for him yet. Maybe when he is bigger, it will be more appropriate for him.
Thanks for great dog toys.
