How do I get my puppy to potty when I let it outside? He/she runs around outside for 20 minutes and then comes inside to go potty.
Potty training can be a lengthy process but don't give up; all dogs/puppies are potty trainable. These steps are meant to be used together - don't try to cheat by only using the steps that are the easiest. All of these tips are important for success.
