Dog humping?

Brittany
Ok so me and my husband are the dinner table playing Magic (a card game) and our dog is not fixed so he's just recently come into this bad habit of humping. Well I hear our child laughing and I turn around to see my dog violently humping her and I couldn't help but to bust out laughing. My husband scolded me because I laughed. Our child is fine, there is nothing wrong with her she's playing with toys but my husband literally scolded me for laughing at how awkward it was to see that. Does anyone else feel like I was wrong for laughing? Or would you have done the same?
