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.
Usually they will have the first cycle around 6 months of age. In my experience as a dog owner, dogs' periods come twice a year and last from a week to a month. During this time, they are extremely horny and beckon for other dogs to hump them, which other dogs often do regardless of gender.
