I bought the large. Its okay, but my golden can't get the last little bit out of the middle. I never froze it, will try it frozen next time even though I don't like to serve anything frozen. May last longer then
Just a note. I purchased 2 small ones somewhere else. Dimension is not 3 inches, its more like 2.70 and thats taken on the OUTSIDE, not the inside, so small would suit teacup or mini. I have two shih tzu's. Small size is okay for a treat, but not to serve a meal in.
WAY overpriced for what they are. I've stuffed large marrow bone for just a few bucks!
