Dogs should be house-trained as puppies; 3 years old is very old to start training the dog. It is sometimes said that you can't teach an old dog new tricks. I would suggest that the dog should be kept outdoors, in a dog house. If the dog house is small (which would normally be the case) the dog will not foul it.
