Can A Muslim Have A Dog As A Pet.?

I am muslim and I have 2 German Shepherds as a pet. But you cant keep the dog inside the house so I got an insulated dog house and put it in my backyard. I also let the dogs in the warm garage that has carpet on the floor with their beds,food,and fresh water. If you are going to buy a dog and it will be an outside dog don't chain him up!!!!!!!!!!!!!! You have to give him a lot of attention.If you are going to put your dog outside then it has to have a big coat.EXAMPLE:Husky,German Shepherd,Alaskan Malamute.I play with my dog like almost the whole day
