However, it is not uncommon for a young puppy to hump. Puppies begin to learn to walk between the ages of 2 and 3 weeks old. Even at this newborn age, some will begin humping as well. When new owners bring home an 8 week old, that puppy may already have a habit of doing this. As the pup grows, at an early age- usually by 4 or 5 months old for toy breeds - the dog will enter into puberty. At this time the sperm is viable and humping urges can be much stronger.
Eight weeks old is when training should start. These days reputable breeders are starting their puppy imprinting at 3 weeks until the dog goes to their new homes. Obedience training can be started immediately. You do not have to wait until the dog is mature in order to train them.
