When my pups are 4-5 weeks, I put a litter box in their pen.
They naturally look for an area to potty away from their bed and food.
You can continue this at your home in an
ex-pen or in everyroom.
If you are having problems with potty training, I have a good friend with 2 pugs, and she
has a way with training.She has the time, patience, and knowledge of animals, kind of a dog potty whisperer.
training, call for fee.
