Why isn t my puppy peeing?

Put her in a small enclosure covered in the potty mats. Once you determine where she is most likely to go, start removing mats she hasn't gone on. Slowly work your way down to only using one mat.

Your responsibility to take her to a vet within 48 hours of getting her for a wellness exam, along with a fresh (less than two hours old) fecal specimen, perhaps also consider a fresh urine specimen as well.

Once medically cleared, get rid of the "little pee mat thingy" and provide walk/elimination times outside, leashed, every 1-2 hours around the clock until she is trained. Allowing her to eliminate indoors will only enforce that it's okay to soil indoors. Clean all soiled areas, thoroughly using an enzyme product specifically made for that purpose.

Constant supervision, when she is indoors, immediate correction when caught in the act, secure containment in an easily cleanable area, only when you can't supervise. Training will require a lot of patience, consistency, diligence on your part, it won't happen in a matter of days, perhaps not even weeks, it may take months, depending on the individual dog and whether it's done properly.

Once trained, you must continue to enforce what was taught on the as needed basis for the life of the dog.

Not the dogs job to let you know when it needs to go, nor will letting her outside teach her anything.

Puppies take a lot of training, attention, and most importantly.... PATIENCE. They will let you know when they have to go: pacing, sniffing the ground, etc.

When you do let them outside, stay with them until they actually go and then praise them. That's how you properly potty train a puppy.

Training is a long process that won't be accomplished overnight.

do not let her see you

How can anything be ''like'' 20 minutes? Is it 20 minutes or not? whats ''like'' 20 minutes?

You have run out of patience after such a short length of time? Did you get a puppy because you thought it would be like a cute little toy? Training a dog to be house trained, and to learn to walk on a lead, and be clean in the house, and come when called etc etc is a long process that takes time and patience. Sounds like you have neither.
