This was a huge hit when I first got it for my one-year-old German Shepherd. She really likes squeaky toys. It was her favorite thing for a week or two and then she slowly lost interest. I've taken it out of her toy basket for a while to see if she'll get interested again when I bring it back. I think it helps to rotate the toys. We did have a really fun time with it at the beginning so hopefully we'll get some more use out of it..
