You do not have to give your dog a handful of treats every time. Use the small treat your dog will work for. For most dogs, just a small nibble of something is enough to do the trick. Some dogs even work for their kibble, one piece at a time. Many dog trainers use tiny bits of cooked chicken, string cheese, hot dogs, or liver. Dog treats are used to attract the dogs. When you train a dog to sit, you can start by attracting your dog with a treat. Most dogs will stick their noses up to follow the dog treat, and as their nose goes up, their bottoms go down. Attracting works well on some other behaviours, including down and rollover.
