No, a lot of dogs I've met have appeared pretty intelligent to me. I can read them and know what they want. They make it obvious in their body language. I think my sister's dog is highly intelligent because she knows my niece and nephew are just kids, and treats them as such, even when they're rough with her, it's really adorable. I don't like kids, but that's another subject. I think it's adorable that her dog acts so motherly, and takes care of other people too e.g. she will jump up onto the top of the sofa and put her paw on your shoulder. It really does feel like she's taking care of people. I love her.
My nan's dog goes to me now whenever she wants something, because she knows I know exactly what she wants. My nan says things like, "I never know what she wants, I wish she could tell me" and always mistakes any attention as the dog being hungry, and I can tell if the dog is hungry, and specifically what food she wants, by whether her face lights up at certain words. I think that's intelligence.
As for wanting my own space, yes, I am in this little room most of the time because I can't stand being around my family and other people all the time. When I mention space and how I don't understand why aspies love it so much, I mean specifically regarding partners and close friends. Of all the aspie men I've dated, the ones who have a need for a ton of space, no, I just don't relate to them at all. It's really hurt in the past, and well, I can't date guys like that anymore.
