Not indestructible but a good try
Color: Printed, Pattern Name: Giraffe
Indestructible is a bold claim- Nice try, but the fluff and squeaker were go e within 12 hours with my aggressive chewer. 3/5 because she still loves to sling it around.

Not for Super Chewers!
Color: Printed, Pattern Name: Giraffe, Color: Printed, Pattern Name: Giraffe
Not indestructible!! Received on 4/28/26 and the arms and legs were ripped off immediately. Two days later the elastic band that made the body accordion like snapped. This morning, 5/7/26, I woke up to stuffing all over my carpet. Not a toy for super chewers.

10 minutes
Color: Brown, Pattern Name: Active Toy
Tough toy for a big dog however, cannot say indestructible! Lasted 10 minutes until squeaker and stuffing were “gutted” from the toy. The ropes were intact long after the body of toy was ripped in half.

Indestructible? Pretty much! I’m very happy with this toy.
Color: Printed, Pattern Name: Giraffe
The only thing that wasn’t indestructible was the elastic band inside must have stretched too far. Otherwise, it seems to be indestructible. Usually a toy lasts about 5 minutes. We have had it a month and I have even washed it in the washer and it still looks new.

Not “indestructible” enough for my pup
Color: Printed, Pattern Name: Giraffe
My pup loves the toy but it is far from indestructible. Only took him 72 hours to rip the ears off & destroy the springy neck part of the toy. So although he enjoyed destroying it, It’s no longer safe for him to play with. For added context, he’s a little over a year old, 50pound, golden doodle puppy. He’s been going through a destructive phase for the last 7 months so this is like toy #30 thats failed it’s “indestructible” claims. The search for a indestructible toy continues!
