Non-contaminating closures may be autoclaved repeatedly without loss of resilience.

Cute Fun Puppies Love it Immediately Good Price
Color: Teething Stick
This little top was a huge success for my active Multipoo! She started playing with it immediately. I think it will become her favorite toy! It isn't expensive. It is well made and very cute!

My puppy loves it
Color: Teething Stick
It's cute and a good size for my chihuahua puppy. It seems to be slightly tearing at the seam in the middle, but hopefully it will hold up.

LOVE this tough toy! My teething puppy is still enjoying it!
Color: Hedgehog
LOVE the hedgehog! Very tough! My dachshund has not been able to chew off any of the 'nubs', and does she try! lol The only thing is, the first thing she did was chew off the nose, but I discarded it and watched her closely to make sure she didn't chew off any more, and no, its still being chewed on.
Wish I could find more toys like this one!!

still searching for a truly indestructible dog chew toy
Color: Hedgehog
My smallish dog (15 lb Boston terrier) got this chewed up within a half an hour. I didn't notice right away that he was also eating the parts he chewed off. Didn't last a day. Otherwise, quick shipping for a cute toy.
