What happens in other countries isn't relevant to your choices. Culturally I was raised to eat meat but I don't. Similarly you could choose to do things differently. Hiding behind 'it's normal' doesn't address the fact that pigs and dogs are of a similar intelligence.
I could, but because I see things differently to you, I don't.
Anyway vegetarianism is just as cultural in the uk as eating meat.
I'm not hiding behind its normal merely pointing out some meats are more normal in some cultures than others, and people do eat dog, just not in the uk.
I don't think pigs and dogs do have a similar intelligence. A dog has been used to do various jobs because of its usefulness and intelligence.
I've not seen any guide pigs, or police pigs lately

Horses are different, you have the mounted police.
Horses and dogs perform work, pigs don't.
That's because they are not comparable, and babe was just a movie.
Dogs, cats, horses are working animals.
Pigs arn't.
In the uk we don't tend to eat " working" animals.
A cats job was to be a good ratter around the barns, less a working animal and they tended to get shot if too numerous.
In the uk we tend to respect animals that " work" in as much we don't tend to put them on a menu.
Pigs don't , therefore we eat them.
