Vital Essentials Freeze Dried Dog Treats | Chicken Breast, Single Ingredient | Premium Quality | Grain Free Training Treats for Dogs, 2.1 oz Bag

If you’re in the US, most boutique dog shops will have lamb lung in bulk. You’ll have to cut it up for small pieces but it’s fairly cheap from what I remember the last time I bought it, since it’s so light weight. Costco sells beef liver, can’t remember the brand. But if you want the chicken, my picky dog loves this stuff from Vital Essentials. The brand has more than just chicken so you can try out a couple flavors to see which one your pup prefers. I’ll add, that the liver is higher in fat so be careful on how much you give of that. The chicken and lung are much leaner meats and less likely to give diarrhea if the pup can’t handle lots of fat.
