Bite as Cookie is a metaphor for reinforcement with a disc or a bite on a toy.
Handler’s often do not treat the disc or the tug toy as a cookie, and focus on the disc or tug as criteria to be hit or a behavior to be performed.
Give the Bite cue as you would a discrete, food cookie.
If toys are treated as cookies, the dog will respond to toys like she does to cookies.
Be sure to offer a cued Bite as reinforcement for set up moves and other skills your dog performs correctly.
