We recommend a variety of chew sizes and toughness not only for dental benefits but also for nutritional variety. This is why we don't offer a box with only light chews.
In addition, we are limited on light chew options and sourcing is our biggest challenge. A box of light chews would likely contain duplicates each month and not provide your dog with any nutritional variety.
If your dog struggles with heavier chews we recommend the mini box ($35). This includes 1 bag each of light chews, muscle meat, and organ meat.
