Summarize this article in one sentence.
Use a stool, ottoman, or other sturdy object that your dog can step up onto without jumping. When you're starting out, it's best to just have your dog step up instead of going for a full jump. That way, it'll be become more comfortable with the concept of getting onto an object. Show your dog the treat and hold it above the stool or ottoman. Say "Jump!" and, if necessary, physically guide your dog onto the object. Give it the treat and offer lots of verbal praise as soon as all four paws are on the object. Repeat the stepping up process in 20 minute sessions until your dog is comfortable getting onto the object and consistently follows the command. Once your dog confidently steps onto the first object, switch to a slightly taller object. Keep increasing the objects' heights until your dog has to complete an actual jump to get the treat. Once you've trained your dog to jump onto objects at home, you can use the same method to teach it to jump onto benches, walls, and other obstacles you come across during walks.
Start with a low, sturdy object. Hold the treat above the object and give a jump command. Move on to taller objects gradually.
