Perfect size for our pup's mouth, great squeaker, stuffed well, decent fabric. The only downside is having to "surgically fix" them from time to time, only because she plays with them so much. She's not a heavy chewer, so beware if your pup is. It's also great to have multiple so she can play with a backup while 'mom' fixes the others.
positive
