Just got a puppy Elkhound, only 8 weeks old and she loves it, my 3 year old Elkhound loves it too.  Of course the older one doesn't like the squeakier in it and takes it out.  They both fight over it so I had to get another one!  Holds up to a 3 year old that destroys all other toys I get!  The small size is way too small, but is still OK.
