Plastic stuffing in it
Color: blue
I was concerned when I started finding little pieces of plastic wrap around my house. Where did it come from, I wondered? When my puppy is shark “no stuffing” toy to me, I found the source! The fin he ripped off that crinkled was full of little plastic pieces of plastic wrap. And it was all over the houses.

GREAT PUPPY TOYS!!
Color: green
It’s great for a puppy. My dog Is 2 1/2 years old and still plays with them. They have withstood 2+ years of a puppy chewing on it and playing tug of war constantly. I recommend this toy for puppies and older dogs. Very good quality!

Not very durable
Color: green
These toys are fun for my dog to play with but the alligator one, the rope started to come unraveled. I was able to pull it off and throw it away and the toy is still okay. Not as durable as I would like.
