**State College, PA** – Why do dogs have such a fascination with garbage? According to Associate Teaching Professor of Small Animal Science at Penn State, Nancy Dreschel, the answer lies in their powerful sense of smell and ingrained hunting instincts.
Dogs possess an extraordinary olfactory system, with 300 million scent receptors compared to humans’ mere 6 million. This highly developed sense allows them to detect even minute traces of appealing scents, making discarded food scraps, even seemingly innocuous items like used tissues, irresistible. To a dog, a trash can is a buffet overflowing with tempting smells.
Dreschel explains that this scavenging behavior is a remnant of their evolutionary past. Prehistoric dogs survived by scavenging scraps left by humans, and this innate drive to hunt and forage remains, even in pampered modern pets. The thrill of the hunt, the digging and sniffing, mimics the behavior of their ancestors tearing apart carcasses. While today’s garbage differs from prehistoric remains, the lingering food smells trigger the same instinctive response.
While this behavior might be amusing to observe, it poses potential risks. Consuming trash can lead to serious health issues, including “garbage gut” – a life-threatening condition resulting from ingestion of plastics, bones, chemicals, or spoiled food. Dreschel has treated dogs suffering injuries from sharp objects in the trash and even performed surgery to remove a corncob from a dog’s intestines.
To prevent dangerous encounters with the garbage, Dreschel recommends investing in secure, latched trash cans or storing garbage out of the dog’s reach. While it may be difficult to completely curb this ingrained behavior, taking preventative measures can significantly reduce the risks and keep your pet safe.
