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.
I do not recommend puppy parents to use this system unless the puppy is an apartment dog and will continue to use a potty station. It is recommended that when you first get your puppy at 8 weeks or older, you immediately begin the type of potty training that will be routine, i.e. outside. All dogs prefer to go outside.
