I have a dog, and I generally agree with the notion.
But, this is about Muslims isn’t it,? I wouldn’t be surprised if there is another one about bacon. This ad is pandering to the populace in the UK who is tending towards racism and xenophobia, most against but not limited to muslims. From market research standpoint, the same populace is probably also big on alcohol consumption so from perspective of market recognition and penetration, this is quite clever.



It’s not that all Muslim’s hate dog (1. dislike is not the same as hate, and 2. of course you can’t generalize all muslims dislike dogs). But stricter practitioners of Islam don’t keep dogs for the similar reason they don’t consume pork. Something about dirty animals (haram).
Don’t take my word for it [1] [2] [3]
To quote directly from some scriptures (copy pasted from the third link) :
I doubt however many Muslims know why they shouldn’t have dogs as pets as usually they are just told by their parents or elders that they shouldn’t. It’s the same thing in all religions.
