To editors like this, it doesn't matter much what kind of interpretation is assigned to point #2: the TAB character in a file could be interpreted as being mod-2 columns, mod-4 columns, or mod-8 columns.
About 8, 9, 10 weeks. After about 8, 9, 10 weeks of age, or when the puppy arrives at it's new home, the dog should be taught to go potty outside. Do not have paper or potty pads inside your home. Peeing is for outside only, or you are teaching your new pup it is okay to potty inside your home.
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.
