According to a 2015 study published in the National Library of Medicine, common food allergies for dogs are beef, dairy products, chicken, and wheat. Our treats are free of chicken, beef, and dairy. Only one treat flavor has wheat (Beau Bites), and we plan to remove that ingredient in the future. All other flavors are wheat-free. We also have some options without egg and soy as some dogs have allergies to those ingredients as well. It should be noted that some of these studies are mixed in their findings. My own dogs have food allergies that I’ve tested through elimination diets, and I have several other friends and family members whose dogs have food allergies. It’s hard to find options for our pups sometimes and we just want to make it easier for you. Not to mention, if you have your own preferences for your dog’s diet, we hopefully have an option for you.
