My girl loves these! It doesn't take her long to demolish them and she is a 20lb dog. If she was a large dog I would be more concerned she might swallow them whole. I find if I give them to her while still mostly frozen so she is forced to munch on them so they last a bit longer. Kind of seems like they floss her teeth as she chews at the webbed part of the feet.
