If your dog isn’t food motivated, there are plenty of non-food rewards you can explore with your dog:
(1) Verbal praise
Don’t be afraid to use gooey baby-voices to praise your dogs. Dogs tend to find high pitches to be more intriguing and exciting than lower pitch sounds.
(2) Praise by petting
Does your dog love getting their butt scratched? This can be a way to reward their behavior–just be sure not to overuse butt-scratching outside of training sessions.
(3) Other non-food motivators
Distance as motivation (if your dog likes their space!), play as a motivator (throw a tennis ball, play tug-of-war, etc.), and anything else your dog loves!
