Mary Randall recollects patrolling the Future War with dogs and detecting an Infiltrator in a poncho.

Dogs are well-known for their ability to detect Infiltrator units. They frequently start barking when an Infiltrator gets close to them.

Ever since Skynet developed T-800 Infiltrators with living tissue over a metallic endoskeleton, the Resistance has had a hard time identifying Infiltrator units. As a result, a significant number of Infiltrator units have been able to breach Resistance defenses and slaughter Resistance soldiers. However, the Resistance has found that trained "sniffer" dogs posted at checkpoints are effective at detecting this new threat.

Resistance members allow dogs to sniff hands and this is possibly because dogs are able to to smell the difference between a human and a Infiltrator.[1]In addition, a dog can be trained to hear the sound of an Infiltrator's servos moving, which is too low to be detected by humans.[2]

In order to counter the detection by a dog, Skynet develops the Hypersonic emitter to neutralize animals.[3] In the NOW Comics timeline, Skynet developed the Big Bad Wolf as a counter measurement to dogs.
