My 12yo senior yorkie mix has lost most of his teeth so he can't chew hard things. I tried dried beef esophagus strips in the past, which were great but splintered into sharp pieces and I worried it could poke his insides. These haddock skins are crunchy enough to be satisfying but crispy and thin enough that he can still break it down with most of his teeth gone. He can be picky about treats but he absolutely loves these!! I am hoping that the Omega3's in it are also helpful for his joints and kidney disease.
