I don't know anything about your dog.
In high school my family had an exchange student. She had the perfect level of English fluency - the level of French fluency I hope I have - where everything she said was technically right, but sometimes just a little tiny bit wrong.
The best example is one morning she looked down at our dog and asked: “Is your dog a man?”
“He’d like to think so,” I said.
Our dog’s name is McGee, and he is a man. But if people think he’s a girl, or a woman, I don’t correct them.
If someone says “She's so cute” I don't correct them, they're right. My dog is pretty cute, I think. The "she" part doesn't matter so much to me. Dogs aren't boys. Dogs aren't girls. Dogs are dogs, to me.
If someone says “Why does she smell that way?” I don’t say it's because he’s a man and that’s what men smell like. I usually just say that we don’t wash him very often. The groomer said he has sensitive skin so we’re not supposed to. Try standing further away if it bothers you. Or stand upwind maybe.
It’s ok that our dog is sensitive. Our dog doesn’t care if you call him a him or a her. I'm almost positive our dog doesn't subscribe to any traditional or even non-traditional gender norms. All I really know is he’ll lick up his own pee if we don’t move him along fast enough. Licking pee is something our dog avidly subscribes to.
Wikipedia says that being soft, dependent, and emotional are feminine characteristics and my dog is all these things. If you count leg-humping as being sexually aggressive, that’s a masculine trait. But if you count leg-humping as flirtatious, then it's feminine. Our dog has a few different styles of leg-humping for different occasions.
The point is if you have a great dog, and I bet you do, I’ll want to ask “Can I pet him” or “Can I pet her” and honestly I can’t tell if your dog is a boy or a girl, so I’m going to have to guess.
And I’ll probably be wrong and you’ll probably correct me, and that’s fine, but I won’t really get it.
I don't think your dog cares. And I think your dog smells great.
