Great question! Salmon Chips are CRUNCHY Jerky. Great for dogs with good teeth. Great for chewers. Great for teething pups, aggressive chewers. Easy to break into smaller pieces by hand.
Salmon Snax and Salmon Nuggets are SOFT Jerky.  Great for dogs who have trouble chewing, crunching. Great for aging dogs who may have poor or few teeth.  Easily to break into smaller pieces by hand.
All Salmon Jerky are really loved by dogs and cats. And they are naturally loaded with Omega 3, which is great for skin and coat.
