These are my husky's favorite toy. She will occassionally take the squeaker out of one, but she has ones that are more than a year old and still in great shape.
I bought this toy because of the great reviews and I thought it was cute. When it came I was disappointed because it wasn't cute at all. I just gave it to my boys and my Yorkie (who has never chewed up a toy in 5 years) got the squeaker out and almost choked on it within 5 minutes. Thank goodness he didn't!! Very, very bad reviews at my house.
These things last forever and both my dogs adore them! The little one digs and digs at his until he "kills" the squeaker. It keeps him busy and relieves us of the job of throwing his little balls for a while. The bigger dog prefers Dotz to all his other toys.
