I think dog owners generally have a lower IQ
I'm not even saying this to try and insult them or be degrading, I genuinely think dog owners simply tend to have lower IQ's than the average person, and I'll give my points as to why.
Firstly, they seem incapable of understanding or engaging with any form of hypotheticals; they are unable to consider or imagine a reality other than simply what they know. I used to think dog owners like this were just being intentionally ignorant, but now I feel as though it's genuinely a limitation to them; they can't imagine not liking dogs, they can't imagine a life where they don't have a dog, they can't imagine why a person may not like dogs, and they also have a complete lack of curiosity to the lives of those who dislike dogs, they have a very black and white thinking.
They also quickly become defensive when someone says they do not like dogs/animals in general, and they take it almost as a personal attack and become aggressive and defensive, and nothing ever seems to be their fault, or they act like they are the 'exception', they are unable to think critically about themselves, unable to reflect on their actions, and everything they do must be right. I see this a lot on posts criticising dogs, about how they stink, how they act, etc. Almost every dog owner feels the need to comment something along the lines of "oh yeah, I totally get that, not me and my dog though!" YES, you and your dog.
Also, on posts about some violent dog attack, dog owners seem unable to engage with empathy for anything besides the dog. There are too many "baby viciously mauled by a pitbull" posts with dog owners under it spewing the same sort of comments almost instinctively, unable to sit back and engage critically with the content
"The baby must have done something to provoke the poor doggo"
"Dogs can sense when a person has 'bad vibes' and may attack on the basis of those bad vibes 🤷"
"omggggg I feel so bad for the poor puppersssss, is it going to be put down???😟"
It's the same repeated comments that lack any empathy for humans, which is honestly quite concerning and endlessly frustrating to see. They don't think, they just act.
They also display a lot of rigid thinking with no reasoning behind it "I can't imagine ANY reason why a person shouldn't like dogs" "I don't trust people who dont like dogs tbh", its all about putting themselves in the morally superior postion for the act of liking dogs, while trying to cast people who dislike dogs for ANY reason as weird, dangerous, not safe to be around etc.
I also think it's so odd the way they completely excuse their dogs' behaviour. I do think dogs being badly behaved is mostly on the owner, but if dogs need to be TRAINED not to be aggressive or display bad behaviours, then most people should not have dogs. I used to like dogs from a distance. I knew my lifestyle wouldn't suit a dog, and I knew I wouldn't be able to properly take care of one. This was the reasoning as to why I did not get a dog, and I'm endlessly glad I didn't now. Which is a big contributing factor as to why I feel as though dog owners have lower IQ's. Far too often, a person's life halts when they get a dog because they can't take care of it. The rise of 'doggy daycares' makes this evident. It's a complete lack of thinking about the future, and is so avoidable with a quick Google search. Seeing very active dogs like huskies in cramped apartments because their owner genuinely couldn't think to do a Google search of what animals are suitable to live in an apartment space is mind-boggling, but not surprising when it comes to dog owners. They cannot think beyond "awwwwww that dog looks so cute, so I'm going to get one", no thinking about their current situation or if they can even take care of a dog, just they want one, so they HAVE to get one.
(I also think there has to be some deficieny in your brain to find a majority of dog breeds 'cute', how do people find pugs who are genuinely abominations who can barely breathe or move without pain cute, I feel bad for the little guys honestly, breeding animals for 'cuteness' and not for the actual health of a dog breed is probably among some of the worst things humans just...casually do. And not to mention those humongous dogs like pitbulls who just slobber endlessly? It's genuinely disgusting.)
