By using a lick mat, you're encouraging your dog to lick, which releases pleasure endorphins. When dogs are stressed, these endorphins can help calm them down. Lick mats, provide:
Stress relief.
Mental stimulation.
They can be great for calming/positive reinforcing activities like nail trimmings and baths
Encourage slower eating habits.
Mental stimulation for dogs on restricted exercise.
It works by spreading a thin layer of dog food like wet dog food, peanut butter, yogurt onto the mat's surface.
