The first large (extra?) Lambchop I purchased came from Amazon, and my destructo-dog loved it.  He seems to have a preference for toys with squeekers.  It is about half his own size, so he has some difficulty getting a grip to tear things off because it is so plush. While I am a little frustrated by the squeeker moving around in the belly of the beast, the search occupies him.  Then I purchased the smaller one (twice) from the grocery store aisle - one to play with while the other is in the wash.  He knows there are squeekers in the paws, but hasn't been able to "work" them and focuses on the belly squeeker.  The top seam on one of the small ones did come apart even though it was in a laundry bag and is awaiting my repair. I have found them to be worth the expense.  Other toys have not survived his concentrated efforts to dismantle, puncture, shred, or eat them.
