These are very cute and so far my dog has not destroyed them and he’s a very aggressive chewer. They are great quality. The colors are vibrant. Rocky loves the squeaker. They're light weight and the perfect size . He enjoys playing with them. We like to take them when he’s not looking and throw them to watch him go fetch them.
