Humping
Humping is mot necessarily a sexual or dominating thing for dogs. The behavior is harmless and they engage in the act in a playful manner. Whether it be objects, animals or people although a bit uncomfortable they are just being playful.
Sniffing Butts
We are well aware that doghs have a way more heightened sense of smell, 10,000 times better than ours. Well, by sniffing some butts they are simply getting acquianted with a fellow dog friend. By sniffing that area they can tell diet, temperament and gender. It’s truly quite amazing but we are grateful that this is not a thing humans do.
