My pup goes crazy for these! Kea has tried chicken hearts before but this was her first time trying duck hearts and it was love at first bite. These are the perfect size to stuff into her enrichment toys and it keeps her busy for a while. I love that it's packed with nutrients as well! We've also taken a handful in our treat pouch when we take Kea hiking and they're excellent high-value snacks that keep her charged up while we're out in the mountains. Definitely love these ones!
