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.
Between two and four weeks old, puppies usually begin to growl, bite, wag their tails, and bark. Puppies develop very quickly during their first three months, particularly after their eyes and ears open and they are no longer completely dependent on their mother. Their coordination and strength improve, they spar with their littermates, and begin to explore the world outside the nest.
