A bedbug sniffing dog can cost anywhere from $500 to $5,000. The price depends on the training and experience of the dog, as well as the specific needs of the customer. Generally, a bedbug sniffing dog is used to inspect hotels, apartments, and other public places for the presence of bedbugs. The dog is trained to alert its handler when it smells bedbugs, and the handler then uses a vacuum to remove the bugs.
