Because most of them are here to whack off. Almost none of them own a dog, most have never been in the same room with a dog. It's all this giant cyber whack off fantasy.
And as for the "women"....the big majority of those are ALSO men, just cyber whacking from the other side of the fence, because if they cyber it as a girl, that means they aren't gay......whatever mental gymnastics are needed, I guess.
Very rare occasions, when the person IS actually what they claim they are, they bail because it all gets too real, too quick.....by too quick, I mean EVER. MOST of these shitstains who ghost out are just fake all the way around, but, there are a select few that simply wet themselves at the thought of meeting a real human face to face because most of these autistic fucks wet themselves when they have to talk to the checkout girl.
MY advice to the OP, or anyone else having this problem consistently is to take notes. Any behavior that you CONSISTENTLY notice that all these fucks seem to have in common, put that on your checklist......and, going forward, ANY of those things on your list that pops up in future conversations, cut bait and stop wasting YOUR time with these time wasting fuckers.
