I drank this coffee over 30 years ago when I lived in The Netherlands. So glad that I can get it through Amazon. Strong, full bodied but easy on the tummy!!!

Go to Costco, and you can buy lower than this  price per oz. Currently $32 ($3 off regular $34.99)+ tax for big size = 0.83$/oz.  Besides, it is more convinient to return if you kid does not like this formula  Be careful, many times some sellers over price a product, and still make the product rank in the best sellers.

My puppy is teething so I had previously purchased the original Nylabone made out of flavored plastic. The dog loved it, not super excited about the regular bone but she did put a lot of work into destroying it. When she finally finished the original plastic bone I decided to go back to the store and grab some more. I was looking around and came across these, "natural," flavored bones and thought.... "SWEET!!! Same great bone but easier to digest!" How wrong I was. First off this is NOTHING like the plastic teething bones. They crumble easily... and by easily I mean my 3.5 month old Wheaten Terrier destroyed these in less than 30min, and she's only about 15 pounds right now. They are recommended for dogs 6 months + with pretty much a full set of permanent teeth because they can shred the bone more easily and to a finer debris. For my dog this was BS... she destroyed these into tiny little flakes that can be easily digested AND managed to get them all over her underbelly and tangled in her fur. The mess wasn't an issue.. the durability was. This is basically an expensive treat, I much rather give her bullysticks over this as a treat (and they last longer). If your dog is teething, this is def NOT the Nylabone version you want. Stick to the original plastic flavored bones or frozen towels. Both work great.
