I'm not sure the comparison to dogs is all that helpful anyway given that dogs have skills humans lack (and lack skills that humans have).
What I would say is this. Since the pushback against male people in women's spaces began, there have been a lot of claims from the trans activist camp that women who don't present in a stereotypically feminine way are frequently being mistaken for men and challenged in women's toilets.
In many cases it is very apparent that the people making these claims are lying. There was one particularly flagrant example in Pink News where the woman who was supposedly mistaken for a man was a very pretty, feminine looking woman who was just wearing a hoodie. They really must think readers were born yesterday if they think any of us are going to believe that that woman has ever been mistaken for a man.
So whilst I acknowledge that it is possible that some women have been mistaken for men, and that you may be one of those women, it is also important to acknowledge that this is something people lie about on the internet all the time, and we have no way of telling who is lying and who is telling the truth.
Humans, particularly women really are incredibly adept at telling what sex someone else is. Perhaps a small number of trans people genuinely do "pass", but I've clocked so many who don't. And I've seen a great many non-feminine women and never had a single second's confusion.
In addition to this, trans women are much less likely to "pass" than trans men due to the irreversible effects of testosterone on the adult body. But in order to "pass" as a man, a trans man would have to not only be bigger than the average woman, they would also need to take testosterone to alter their hair growth pattern, voice and musculature, and either have a mastectomy or bind their breasts. Those things don't happen overnight, or by accident. They are deliberate and permanent interventions performed on the female body with the express intention of making that body appear male. It's not really the kind of look that a woman can achieve just by being a bit butch/flat chested and cutting her hair short.
The other issue is that we have all spent the last decade or so being told we must not challenge a trans woman (i.e. a biological man) in a women only space. And indeed many or even most of us would be afraid to challenge a male person in women's toilets or changing rooms for fear of him reacting in a violent way. As such, people challenging someone about their right to be in women's spaces is not something that happens very often even when it is perfectly obvious that the person is male. So what you are asking us to believe is not only that a female person has been mistaken for a male person, but also that that female person was actually challenged about her right to be in a women only space. Both of those things are unlikely to happen on their own. The chance of both those two things happening in combination with each other is really very tiny indeed.
So maybe you feel that the responses to your post about being mistaken for a trans women are insufficiently respectful. But try to see it in the context of everyone here being bloody sick of hearing these stories from an increasing number of people who are clearly lying.
And as many others have pointed out, the knowledge that women's spaces are indeed being used by biological males has certainly made many women a lot more nervous about this and more inclined to second guess women who look a bit masculine. This isn't the fault of the women who just want their single sex spaces to actually be single sex. It's the fault of the male people who have been using women's single sex spaces without our consent. So if you have actually been mistaken for a trans woman and challenged about your right to use women's toilets, I'm very sorry that happened to you but please direct the blame where it properly belongs.
