Huh, this is an interesting topic, it's something I've been thinking about lately because I work with dogs, I work for a doggie daycare at a very large pet resort.
I'm pre-everything so what I'm wondering is if the dogs' behavior towards me will change when I do. We have a lot of dogs who were abused rescues and many of them are scared of men.
I'm pretty sure the dogs that already know and love me will still recognize me, dogs go mostly on smell for everything they perceive, and even if my body odor changes, it should be similar enough for the dogs to pick up on, and also many of the smells from home I bring in with me on my clothes and belongings will be the same.
I do think that a lot of fear from new dogs towards men stems from their lower voices though, so I'm thinking if my voice drops significantly (it's already on the lower side of things, for a female anyways), I might have issues with some newer dogs. I have to say, it would depress me a bit to have dogs cower from me where they wouldn't before, but I know enough about canine body language and warning signals that hopefully I could adjust and utilize ways of approaching them more gently so as to not cause them as little stress as possible.
On the flip side we've got a giant Alaskan Malamute who's kind of a punk in daycare who only seems to listen to men. The only time he'll listen to me even is when I yell in the lowest voice I can muster at him. It'd be awesome to have him stop humping the other dogs when I tell him to without having to wrench him off of them. XD
