P.O.S.
Color: Grey, Color: Grey
Toy is not as advertised. It is NOT for aggressive chewers. It is NOT indestructible. It is NOT for medium to large dogs. I knew the moment I opened it that it would be demolished by my 24 pound Miniature Blue Heeler. And here we are 5 minutes after giving it to him, picking up pieces of cotton off of the floor. This should be marketed as a kids stuffed animal. In no way shape or form is this a chew toy unless you have an aging toothless two pound Chihuahua. It would have taken longer for my dog to chew up the $10 dollar bill I gave for this. 💩

Great for aggressive chewers
Color: Grey
Tuff toy, my yorkie has been trying to tare squeaker out for about 3 days, he works on the fur part but so far it stands up to his chewing, I have gone thru 3 other toys this week so glad thi one works! It lasted 8 days. They need to make whole toy out of material and put fur on top of the tuff material. Once he found out wetting the fur softens it he pulled the seam apart.

Does not stand up to aggressive chewers
Color: Grey
Supposed to be for heavy chewers. My dog destroyed this toy literally in less than 15 minutes. Tore the tail which I sewed back together and then she tore off the nose and pulled out stuffing. Don't know how they tested this. She is only 6 months old and it didn't stand up to her play. Do not recommend if you have an aggressive chewer.

Won't last a day
Color: Blue, Color: Blue
My 50 lb. Pitt bull destroyed this chew toy in 15 minutes.
One week later.
I'm changing my rating from a one to a five. My girl spent up until now ripping it apart and pulling the stuffing and squeaker out. She had so much fun that I bought her another one. When I took it out of the box for her, she was so happy, she immediately tried to tear it apart.

Lasted 2 minutes
Color: Grey, Color: Grey
Gave it a 2 star bc it was cute and on time.
I have a GSD- a mildly aggressive chewer. This toy literally lasted 2 minutes and there was stuffing coming out so I had to take it away. Wish I would have read the reviews before I purchased.
