After the petfood recall, I replaced my dog's biscuit treats with Dogwell's Vitality dried chicken breasts, as they contain nothing except chicken. With the recent scare about Bestro's dried chicken breasts (sold at Wallmart) coming from China and causing illness, I looked more closely at mine, and found in very small print that although they are distributed in the U.S., they are also manufactured in China. So I was back to square one on what to give as treats. I found 2 that have minimal ingredients in them, and primarily meat, and my dogs both love them.
Wellness Pure Rewards (moist jerky treats): ingredients - meat, dried chickory root, cultured whey, sea salt, lecithin, garlic, and mixed tocopherols (a natural preservative). 95% high-quality real meat from the US and Canada; no grains, wheat, meat by-products, artificial colors, flavors or preservatives. I purchase mine at Only Natural Pet Store; link is on the right.
Charlee Bear treats: ingredients - ground chicken, broccoli, spinach, carrots, sweet potato, turkey livers, turkey hearts, fish meal, ground almonds, natural flavors and dried kelp. (58% chicken, 12% turkey, and also grain-free).
A 3rd option is Newman's Own Organic Dog Treats. Although it doesn't contain meat, it has good ingredients and all are certified organic. It can be purchased at Amazon.com or Only Natural Pet Store; links are on the left.
