I have a boxer/pit mix and she loves this! I bought it 4 months ago and it’s still going strong so I know it’s quality made and perfect for dogs that like to chew and play tug of war. It has been chew resistant for my girl and she loves the little squeak. I just throw it in the washer when I wash her bed. Great value and a safe toy that’s a good size for a medium to large dog.

Favorite toy

Pattern Name: Octopus

My 80 lb American bulldog and staffy mix absolutely LIVES this little octopus. He literally destroys everything but NOT the octopus, lol. It is well made and has lasted months which is a huge deal. Great buy

Large & Well Made

Pattern Name: Octopus

Although quite large for a small dog it does provide lots of entertainment. It's soft has crinkle in the legs which does entertain my little guy.
