Dog in the car

I am a Muslim, I work as a taxi driver with a capacity of 10 passengers and I serve every person .... The practice in European countries and Israel is that treating animals is more important to them than people and they consider it like their son, and what is meant by animal is a dog that is considered unclean for us except in special cases such as hunting And guarding, and the dog among foreigners is known to everyone that it lives in their homes and there is special food for dogs and they sometimes feed it from the food that they eat from, and he does not look for unfit food on the streets .... My question is: Do I have the right as a taxi driver to carry the dog inside The taxi is with his owner and I travel with them to their country, and if the dog is near me, will the impurity affect me? Do I have to clean the car when they get off it? And if the dog is spared in the car, do I have to purify it? What is the process of purification in this case?
Thank you, and may Allah reward you.
