When at home, we recommend putting the dog out to potty at least three times a day: in the morning, after dinner, and before bedtime. If you have a fenced-in yard with a wooden fence, we also recommend installing a dog door into your back door.
Note that when you are out working out in public with your service dog, we recommend having the dog potty against a tree right before you go into a building. Even though we recommend working only two hours at a time, it's easy for a dog to confuse a mall that has trees (for instance) with the outdoors--and we always want to set you up for success. This procedure helps a lot.
