Love these!!
My dog absolutely loves these toys!! I’m grateful they don’t tear up easily because he’s really harsh on toys. Love that you can add treats or a water bottle to get more engagement and enjoyment. This by far is one of my dogs favorite toys. Great value for the money and great quality.

My dogs love these toys!!
My dogs went crazy over these toys. They love them. They are so cute. They are the perfect quality chew toy for dogs who love to chew toys apart. Perfect size for smaller dogs. They love to carry their toys around all over the place with them.

No chew resistant for heavy chewers.
Not durable for a heavy chewer. I went by the reviews which said they lasted and were chew resistant. Ha! Not so with my Brittany Spaniel. She chewed this apart within hours!

indestructible!
these are so cute, squeak but my puppy who chews everything from rocks to shells was unable to tear these toys to shreds or even bite it into pieces. she actually gave up and grew bored with them which has never happened with any other toy or item she fixates on and eventually destroys.
