For those that may be unaware, which I imagine won’t be many, faux scents are bottles of liquid that you can get from a hunting store that is supposed to mimic the real thing. They have scents such as rabbit, deer, hog, various birds and fox just to name a few. The short answer to the question at hand is no especially if you have a dog that does conservation work or off leash work around potential wildlife. It is tempting to think that “if I just associate this exciting odor with my dog’s toy that should be enough to fulfill his desire to go after the real thing”. While I’m sure there’s a dog out there that could put two and two together in that context the vast majority of dogs with a high desire to SEEK out interesting things, such as wildlife, may not. This is especially true if a dog’s SEEK is focused more on wildlife instead of their target odor whether through distraction or immaturity. The ability to have a dog successfully understand and accept the replacement without any bleeding towards the real thing will decrease when the dopamine response of what they really are interested in (wildlife) is paired with an outlet that allows them to practice the unsafe portion of the Predatory Motor Pattern (chase, grab-bite, kill-bite) especially without the completion of the PMP (dissect and consume). This leaves an unintentional void within the dog which may lead to them SEEKING out the real thing. This increases if the dog has been successful in the past chasing wildlife and if the faux animal scent used is one that can be found in your area. Your dog may either stop looking for their target odor or abandon the task once a “more interesting” odor crosses their path. Now I don’t anticipate anyone here using this approach but just in case you or someone you know has a dog with this exposure history, whether it was to try and remedy the unwanted chasing or perhaps a gun or hunting dog that is now in a home that does not provide that outlet for whatever reason, counter conditioning that is going to be very tough especially if the dog has a lot of experience under their belt with this lifestyle. In some cases, it may be impossible and perhaps finding a more suitable living arrangement is in order.
