Behavior
Bush dogs are remarkably social and secretive canines that live in tight-knit family packs of up to a dozen individuals. Unlike many other wild dogs, they are strictly diurnal, meaning they are active during the day and retreat to burrows or hollow logs at night. They are famously vocal, communicating with a range of high-pitched whines and barks that help the pack stay coordinated while moving through the dense understory where visibility is low.
These animals are semi-aquatic and are exceptional swimmers, often seen crossing rivers or even hunting in the water. Within their social groups, they exhibit a high degree of cooperation; the entire pack helps protect and provide food for the offspring of the alpha pair. While they are naturally shy and avoid human contact, their curiosity and pack-driven boldness make them formidable hunters capable of taking down prey much larger than themselves.

Camera Tips
Because bush dogs are so low to the ground, camera placement is the most critical factor for a successful capture. You should mount your camera no higher than 8 to 12 inches off the ground. If the camera is mounted at the standard 'deer height' of 3 feet, you likely won't see anything but the very top of the dog's back, or the AI may fail to trigger entirely because the subject is too low in the frame. Angle the camera slightly upward if you are placing it on a slope to ensure you capture their distinct facial features and rounded ears.
Look for 'funnel' points near water. Bush dogs are semi-aquatic and frequently use well-worn game trails that parallel riverbanks or lead to shallow crossing points. If you find a spot where a trail narrows between a fallen log and a creek, that is your prime location. Because they travel in packs, it is essential to set your camera to 'Burst Mode' or 'Rapid Fire.' Taking a single photo will often result in a shot of the first dog's tail; a 3-5 photo burst ensures you capture the entire family group as they trot past in a line.
Video mode is highly recommended for this species because of their unique vocalizations. Hearing their high-pitched 'contact calls' provides incredible insight into their social behavior. Ensure your camera's microphone is unobstructed. In terms of lures, bush dogs are very sensitive to human scent, so minimize your visits to the camera site. While they are meat-eaters, they are rarely attracted to standard backyard baits; instead, focus on placing cameras near the burrows of their favorite prey, like pacas or agoutis.
Finally, keep your sensor sensitivity high. Bush dogs move with a steady, low-profile trot that can sometimes fail to trigger older PIR sensors. High-quality lithium batteries are a must to ensure the trigger speed remains fast enough to catch these quick-moving canids before they vanish into the brush. If you are in a particularly humid jungle environment, use desiccant packets inside your camera housing to prevent lens fogging during their peak morning activity hours.
