Not quite "indestructible"
Color: Green+Brown
These toys are so cute! But, they are NOT for aggressive chewers! 15 minutes and they were ruined. But for kinder chewers...they are adorable.

Easily Destructed
Color: Green+Orange
My dog destroyed it within a couple of days. The “rope” turned into strings which is dangerous if eaten

Great for Small to Medium Dogs
Size: Critter Zoo, Color: 5 Different Animals
I bought these for my boys to play with. One of them loves to tear the squeaker out of anything that, well, squeaks. These do more than squeak! So far, they have survived the terrorist chihuahua/piranha boy! They’re pretty awesome toys and my kids’ favorites! They’re sturdy and goofy looking! I’m writing this review a couple months after my purchase. One reason why is I want to “buy again” (just because they have their squeakers, doesn’t mean they haven’t been chewed on!). I have a large, long chihuahua (<—— terrorist/piranha boy) and a min-pin mix. These toys are the perfect size for them. There is some chew damage from the terrorist but considering he can get a squeaker or of a Lamb Chop within 5 minutes, I’d say these toys are the best I’ve run across in quality, thickness of the material, minimal stuffing and durability. Highly, strongly, encourage you to, purchase if you’re looking for good toys for small to medium dogs!
