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.
Small breed dogs typically start having estrus (heat) cycles earlier, at 4-6 months of age, and large breeds typically start later, at 12 to 24 months of age. The estrus cycles vary between each individual dog, average of 7 to 10 days. Some dogs as few as 2 days, some dogs cycle as long as 21 days.*.
