Patton Veterinary Hospital has learned that there has been a video circulating on Facebook stating that Milk-Bone brand dog treats are unsafe and may cause cancer in dogs because they contain a preservative called BHA. We want to reassure our clients that Milk-Bones are safe for your dog and do not pose a risk. We use mini Milk-Bones as treats in our hospital and many of our doctors and staff feed them to their pets. BHA in the trace amounts used to stabilize fats in food is considered safe by the U.S. Food and Drug Administration and is found in many pet foods and treats as well as in our own foods. There are no substantiated cases of cancer or other illness being caused by BHA in dogs and cats. Treats should always be fed sparingly, but the amount of BHA used in many treats and foods should not pose a concern.
