Personally I'm not a fan of paper training. To me, it seems like you're training them to potty INside the house instead of outside. I would take your puppy out every one to two hours and immediately after waking up, playing and eating. Then when she goes potty outside, give tons of "good potty" or "good girl" praises and treats! She is still a baby, so it will take time and patience. Puppyhood is both annoying and a blessing.
I need more advice. I left the back door open for our puppy so she can go out, and she went to the back door but she still pooped in the hall way....what am I doing wrong? I cant be watching her 24/7. HELP !!
You really do have to watch puppies 24/7. LoL! They are a lot of work. You can't just leave the door open. She won't know what that means until she learns that outside is where she goes potty. You just have to keep taking her outside and wait for her to do her business. Bring her to a particular spot every time. And when she does it, give her lots of praise and a treat. Use a special treat that she LOVES, and ONLY use that treat for doing potty outside.
Some other ideas:
You can hang a bell by the door that she can reach. Every time you take her outside to potty, ring the bell. Eventually she will learn to ring the bell when she has to go out, and you should be able to hear it.
You can also tie her leash to your belt, so she has to follow you around all day. Then she can't sneak away when you're not paying attention. If she's near you, you will be able to see that she's about to go potty. Watch for sniffing, circling, squatting, whimpering. Then quickly take her outside.
If she tends to potty in the same spot in the house, it may be that she can smell where she went last time. Use an enzymatic cleanser, like Nature's Miracle, to get rid of the smell.
Do you have a crate for her? Crate training can be great for some dogs. They learn that is their safe spot, like their own little personal bedroom. And crates are helpful when you can't keep an eye on her. It should only be big enough for her to stand up, turn around and lay down. Not too small that she's uncomfortable. But not too big, or she may potty in one corner and lay down in another. And don't leave her in the crate for too long, or she will associate it as a negative place.
I know it's frustrating, but don't give up! Some dogs take longer than other to figure it out, but someday she'll get it. Dogs like schedules. Feed her at the same time every day. Potty immediately after waking up, after eating, after playing, after walking, before bed. Consistency is the key.
