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.

Great!
Surprisingly tough. Holds up to tug and doesn't rip right away like so many soft toys do. Has crinkle legs and squeaky head. Dog is having so much fun

Cute toy and well made
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.
