Not to belabor the point, because you already have some great info, but after having our first dog potty outside until she had to wear diapers, we chose potty pads for the puppies we have now. We are just more aware of the risks to dogs who are barely half the size of our first yorkie when they are in the great outdoors, and there are only two of us at home now to do potty duty. One thing that we like are the Arm and Hammer brand of disposables. My husband says they really have little or no smell. Obviously, we flush poop whenever we see it
.
Just figure out what you like. We have a few washables, and I am thinking of trying those again as well. They weren't a problem, but it is the washable/disposable diaper thing all over again.
Enjoy your sweet dog!
