How Good is a Dogs Nose?Ī dog's sense of smell is incredibly powerful and is considered one of the most acute among animals. In fact, there are specialized sniffer dogs to sniff mercaptan to identify gas pipeline leaks. Dogs are sometimes trained to sniff mercaptan. However, natural gas is laced with mercaptan, which is a very smelly sulfur gas. Methane is odorless to humans and dogs, and as such cannot be detect. Typical gas used in the home is supply with natural gas which is mainly made up of methane. When there is a gas leak, the natural gas can displace the oxygen and reduce oxygen supply, poisoning you and your pet via hypoxia. In fact, the first carbon monoxide alert was a canary in a coal mine since birds are particularly susceptible and often show carbon monoxide symptoms first.

Small animals with less lung capacity are more sensitive to high levels of carbon monoxide than larger animals.
