Indestructible my shiny hiney!! Dog had it destroyed in 6 hours. Waste of $$$
Color: Blue Cow
I bought this blue buffalo dog stuffy toy for my medium sized dog. It says it is for "heavy chewers" and she really isn't a heavy chewer. My German shepherd was a heavy chewer. This little dog isn't. So this toy should have lasted her a couple of weeks at best.
NOPE! NOT EVEN CLOSE!!
She had it for about 6 hours before the seams were busting open and stuffing scattered all over my house. 6 FREAKING HOURS!!!
I'm very upset over this and my son threw it away before I could tell him to let me return it. So that's $6.99 down the drain.
Indestructible my ass. Waste of money and lots of lies on the page. Phooey!

Not so big bull. Tiny in size. Not
Color: Blue Cow
Cute but underwhelmed by the size.
Barely 7”x4”. Missing over 3 inches from description. Disappointment indeed.

Grump lobster toy
Color: Red Lobster
My girl blood-eagled this poor thing within minutes but she had one heck of a time doing it! If you're looking for durable, this probably isn't for you. If, however, you're looking for some quality entertainment for you and your dog, look no further. A little reconstruction and ol' Larry was ready for round two of being eviscerated. Solid toy, real cute.

Not a terrible toy
Color: Blue Cow
Not a terrible product, but for a super sure it doesn’t last very long. It’s cute, but this is meant for definitely a small two small medium dog.
