Expert Perspectives on the Shelf Life of Dog Bones

Dr. Emily Harper (Veterinary Nutritionist, Canine Health Institute). “Dog bones, like many pet treats, do have an expiration date that is crucial for maintaining their safety and nutritional value. Over time, fats in the bones can oxidize, leading to rancidity which may cause digestive upset or even toxicity in dogs. It is essential for pet owners to check packaging dates and store bones properly to ensure freshness and avoid health risks.”

Mark Reynolds (Pet Food Safety Specialist, National Pet Products Association). “From a food safety perspective, dog bones are perishable items that degrade similarly to human food products. Exposure to moisture, heat, and air accelerates spoilage. While some bones may appear durable, their quality diminishes beyond the expiration date, increasing the likelihood of bacterial contamination or mold growth. Adhering to expiration labels is the best practice to protect pet health.”

Dr. Sandra Lee (Veterinarian and Animal Behaviorist, Paws & Wellness Clinic). “Expired dog bones can pose risks not only due to spoilage but also because their texture changes, becoming brittle or overly hard. This can increase the chance of dental fractures or choking hazards. I advise clients to discard any dog bones past their expiration date and to monitor their pets closely when introducing new chew products.”
