I don't know but my dog is 6 months old and horny as hell. He is starting to hump everything. So if any of you have a short little whorish female dog that needs a good one, let me know. We don't have to meet, just the dogs.

Give your dog a large stuffed animal. Poor Boujean was neutered before we could bring him home from the animal shelter, at about 3 months of age. The first night he was home, he was compulsively humping literally anything and everything he could get his legs around. And he was whining and crying while he did it. My daughter had the stuffed dog from the book children's classic book Go Dog Go. Since she never played with it, I gave it to Boujean. And Go Dog Go he did - he humped that stuffed animal all night long and for weeks afterwards, and it has been his favorite toy ever since. The only one of his stuffed animals he has not disemboweled. I am sure it is because it was his first love.
