NERF Dog Treat Launcher Hasbro 2020 Uses the treats that are approx. 2" across, I believe they're the medium sized ones This has been used ONCE My dog ate the treats, given to her by hand, she thought I was trying to kill her when the treats flew at her from the gun All she has to hear was the clicking noise, and she'd disappear underneath my desk My dog was a rescue, and it's taken her a while to acclimate She avoids large open areas, prefers woodsy hikes in the backyard with Mama And once she found her voice, protects the house it's like FORT KNOX She still barks her head off at the burglar, who breaks into our house every night, through the garage - with a clicker!
