I have been buying these for my labradors for as long as I can remember! At least 12 years (since my oldest lab passed away at 13 years old a bit over a year ago). Labs love eating and healthy weight active dog biscuits was the way to treat them without over indulging! I discovered these at my vet's office years ago and figured if she was selling these along with other much higher end and pricey dog foods and treats it had to be good for my dogs, not to mention they were the treat of choice that the vet techs offered my dogs after their appointments. They loved these treats so much that they always walked into the vet's office and immediately (gracefully I might add) placed their front paws on the counter pleading for an Iams Healthy Weight biscuit!!! PLEASE, PLEASE, PLEASE bring these back in production!! My local pet stores (Pet Club, Petco) always sold out of the big boxes of these biscuits!!! Now I have to take the time to research other treats that are as low calorie , healthy, and satisfying to my K9 kids.
