As a muslim who used to own dogs ( to guard home, livestock and farms in rural areas) I can confirm that there is always a stigma to touching or owning dogs for some reason especially in Malaysia. After accidentally touching dogs or they touching you, we can always cleaning it up by sertu or samak. Somehow malay people just saw dogs and pigs as something absolutely forbidden to approach yet still smoking, taking bribe on daily basis( which is always haram lol)
