Relax. It is only day 4. She is a baby and needs your utmost compassion and patience. Put bluntly, you need to buck up a little bit. Raising a puppy is hard work. You have a long road ahead so start educating yourself and that way you can better manage your dog.
-keep the dog on a food and water schedule. that will help you predict when she will need to go
-always take her out right after she wakes up, 10mins after she eats, right when she stops playing, right when you take her out of the crate
-watch for behaviors such as circling, running to the door, whining excessively, sniffing the ground, looking at you for long periods of time, disappearing to a different room or corner - all of these behaviors can be used by dogs to indicate that they need to go. Listen to her cues and respond quickly
-She must always be taken out on lead when you take her outside to potty. When she goes to potty, you must ONLY wait for her to urinate or defecate. Do not play with her, do not let her run around, do not engage her in any way except to walk her around in circles until she goes. When she goes, immediately praise her and treat her. Make it a big party. If she eats snow, keep walking and moving. Don't give in and have patience. I have waited outside in the cold and rain for 30 mins in the past waiting a puppy out, but once they get the idea, they will learn quickly.
-accidents will happen. That's just the fact so get prepared with good cleaning supplies. Get a good enzymatic cleaner like Nature's Miracle or Simple Solution. Blot the area well so all of the liquid comes up. Then spray the cleaner in and wait for it to work. You must clean the area well, otherwise the urine or fecal smell can give the pup mixed signals.
-figure out what her limit is and take her out before she reaches it. If she has an accident if left for 4 hours, take her out every 3 for example.
You must be patient, fair, and consistent. If she whines in the crate, that is fine. Toss a toy or treat in there each time she goes in. Make it a fun time. Do not reward her for whining by letting her out. Feed her meals in there. Throw treats in there to get her used to the area. Soon she will associate the area with positive thoughts and might get better about remaining in there.
