Impurities

Q: I have got the scholarship for further studies abroad. I pray fives times a day.

1. The country I am going to, they eat pork and dog meat. This scholarship will be a life changing opportunity for me but I am worried that I need to interact with the local people on a daily basis, like professors and other classmates. Anything haraam I should avoid while interacting with them like hand shake or exchanging things?

2. I need to rent a room. They normally keep dogs as pets in their houses and fridges are also available in the rented houses in which they keep dog meat and pork. Should I use this fridge, stove and how to clean (purify) this place for living here if they kept dog meat in there?

3. I will offer prayer in that room. Explain briefly about the najasat of dogs and their saliva because dogs are everywhere in this country. They are in public places and sitting onbenches that are basically for humans to sit on.

Q: Yesterday I was having doubts while I was painting my parents house about the paint brush. Today we had half left and when I searched the internet, i found that the paint brush was made from animal hair and it's non halaal. My family members are painting with it before I told them it's najasat because I just found out a moment ago and not yet told them. I have mixed the paint with the brush. Does my house become naajis and what do we do with the remaining paint? If I touch the house with wet hands, does the najasat transfer? This is very distressing. We have thrown the brush but the paint is still left and on the wall. Now must I throw the remaining paint away?

Q: My little brother got urine on his boots at school (at the bottom and top of shoe) and then walked from school to home in the snow, getting them wet. When he came home, he walked through the living room, spreading the wetness from his shoes all over the house. I did my best to wipe all the wetness off the floor but I don't even know all the places the water from his shoes got. Do I consider my living room to be impure? How can I make it pure again? I will have to mop the living room and the rest of the house, it that ok?
