A playful Labrador retriever named Tilly is being put to serious work in Ontario, where she has been specially trained to detect high-risk invasive species before they become established in conservation areas, CBC News Toronto reported. The effort is a pilot project run by Credit Valley Conservation, which hopes the dog can catch threats early.
Tilly was chosen with care. According to the report, she was selected from working-line Labrador retriever breeders, the kind known for a higher drive that suits the demanding, repetitive nature of detection work and keeps the animal focused on the task at hand.
Her training followed a careful routine. Handlers focused on a single target box, feeding her over the target odor to get her acclimatized, then encouraging her to drop her nose into the box and wait patiently for a food reward, building the precise behavior needed to flag a find in the field.
Trainer Tony Pallotta said the project breaks new ground. While the team has worked with dogs to detect bed bugs before, he explained that this is the first time they have trained a dog to detect invasive species outdoors, a first-of-its-kind initiative in Ontario.
What makes Tilly's role striking is how subtle her targets are. She is trained to find the actual eggs and larvae, which give off very little odor, and the fact that she can search large swaths of an area with such precision was described in the report as phenomenal given how faint the scent is.
Her first assignment has a specific target. The immediate focus is the red swamp crayfish, an invasive species that was introduced in Mississauga last year, and Tilly will be used to map just how far the species has spread across the area so a response can be planned.
Credit Valley Conservation says invasive species pose one of the greatest threats to forests, biodiversity and local economies, spreading rapidly and often causing irreversible damage. Tilly is expected to begin her detection work this summer, and while she may look approachable, the public is asked not to interact with her while she is on the job.
