1) There is a Truth (capital T) that exists. Islam is its message. The message is interpreted by imperfect humans (scholars). These scholars are products of their times, circumstances, biases, and more. There are several schools of thought within any single sect of Islam, and therefore there can be wildly different rulings on the very same topic.
2) The internet is flooded by opinions of certain
fiqhs that people search for, find on some "Islam" website, and believe. Diametrically opposite opinions will exist in some other
fiqh or school of thought, etc.
3) There is no evidence that dogs should be hated, banned, etc. Even the
wudu question pertains more to their saliva, which like the saliva of many other animals (including humans, contains a lot of microbes. It's good hygiene to wash your hands after coming into contact with any bodily fluids of any animal / human!
4) In conclusion, dogs are amazing. Many miss their owners/'human parents' even after the human passes away. Many have given their life to protect their human families.
5) Kindness to animals is CENTRAL to Islam. Give a starving dog food or a thirsty dog water, even if it's in your own shoe or hat, and you would have done something that really pleases God.
6) Read more on the long history of human-dog contact in Muslim communities, including in mosques and around places of prayer, as well as how the rabies disease caused attitudes towards dogs to change in many Muslim communities:

You are obviously not from Pakistan and not aware of it dog culture. Ever heard of Bully Kuta, the racing hounds and the Kochis
He's saying something else entirely. Just because there are local dog breeds and dog shows happen, etc., doesn't mean that the entire culture loves dogs. Stray dogs, for example, have a very bad time in Pakistan compared to a country like Turkey where they are protected by the state and treated with respect by citizens. Pakistanis typically like their fancy / pure breeds --- but strays, just because they are considered ugly, are seldom extended the same kindness.
Also, I've heard people say they 'love' dogs only to keep them chained/caged and use for breeding/business. That is not love. That's ego and money. I hope all such animal 'lovers' who only keep pets for selfish reasons and don't give them the freedom and quality of life that they deserve are questioned on the Day of Judgement.
