Correctly targeted by Amazon's suggestion
I didn't know my dogs were crackheads until they tried this. They absolutely loved them. Even my 16 year old RUNS to get them. Definitely 5+ stars.

Tasty treat but better as a quick reward than a long chew
I gave these to my German Shepherd and Lab as occasional treats. They were immediately interested and finished them quickly, which usually means they’re both appealing and easy to eat. These aren’t long-lasting chews—they’re more of a quick snack. For larger dogs especially, they won’t keep them occupied for very long. Compared to tougher chew options, these are better suited for training rewards or short treat sessions. I’d rate them 4 stars. Good flavor appeal, but not designed for extended chewing. Tip: Use them as a reward treat rather than something to keep your dog busy.

Chicken and Peanut Butter - Two Great Tastes That Taste Great Together... to my Dog
My dog is a fairly selective eater, but she loves chicken jerky and peanut butter, so I thought I'd give these a try. She took to them right away, and can finish one off in about 3 minutes. They have a distinct smell of peanut butter (despite peanut butter only being 3% of the composition). Each chicken jerky-wrapped peanut butter biscuit is about 4.5" long, and they arrive packaged in a resealable bag. Made in China; my bag was printed with a 'BEST BEFORE' date over a year from the date I received them. Note that these treats have been irradiated to kill harmful bacteria and parasites.
