Regarding the Nylabones, for my little one everyone recommended the "Gumabone" variety - nothing to choke on! He likes it, but doesn't love it all the time.
Buddy just ripped up a stuffed octopus today in about 30 seconds. The only toys he loves to death and hasn't destroyed (seem really tough!) are:
1. Big Mean Kitty by
http://www.FatCatInc.com - they have TONS of great toys - you can even buy your little one "chicken lips" - they are very tough toys - the Big Mean Kitty I have for Buddy is made of very tough canvas. He LOVES it.
2. The "Petstages" puppy toys are good - though I did have one soft one rip. They have one that has lots of knotted pieces of canvas at the ends and buddy loves chewing on the strings - I guess they're like shoelaces.
His favorite toy by far is his little "Bad Cuz" - here is a cool site that did tests of dog toys for durability for Boston Terriers - I don't think a Yorkie could cause as much damage!
