Products ~ I use Nature's Miracle here for anything animal or human related for that fact. I am not sure if there are better or cheaper products out there as it's like Dawn Dish Soap / Tide / Charmin Blue ~ a house staple we are happy with and don't look for a replacement. Whatever product you select try and be as thorough as you can be, which will be a pain in the tookus ~ but its really worth the effort. Probably wouldn't hurt to deep clean the rugs if you can. I put the enzyme cleaner right in the steamer about once a year just because we have animals and alot of foot traffic I like to get everything out. If you can't spot clean and then steam clean ~ just do the best spot cleaning you are able to do (don't use ammonia or bleach) ~ it really needs to be a product that specifically breaks down enzymes.
Restart like this if you can & other will have good ideas too:
Each time you take her out ~ have a catch phrase "Outside go Potty" / "Potty" / "Let's TCB" something she associates with going outside and doing her business. At first it will seem pointless ~ with diligence you will soon notice she understands and makes the connection.
When I can't keep my eyes or someone else's eyes on ours 100% she goes in her X-pen (they have them frequently on Craigslist for very good prices) with a shower curtain down so if an accident or sickness would happen the floors are not a victim. I have a couple shower curtains (at Lowes, practically given away because a fork truck ran over the package and left tire tracks). If an accident happens remove, wash (I use natures miracle with Tide), do not put in the dryer just hang to dry ~ they dry in a jiffy and replace with the fresh one I have on stand by.
We honestly started at every 20 minutes outside & big praise when she did something. I didn't treat her with food for it ~ some do ~ but I did go happily ballistic and sang songs the whole 9 yards. Wake up ~ go potty / after meal ~ go potty / after play time ~ go potty / after a nap ~ go potty / before bed ~ go potty. At first you are outside more than in
but honest to Pete we have never failed with that method. Even animals we took in because they were impossible to train ~ they were able to be potty trained regardless how old they were. As you learn her signals and she catches on you won't be out near as much. Even at this point with ours ~ she is going on 7 months old and she does not potty in the house ~ we still stick with the above because it takes awhile to set in and become reliable.
You will be able to restart her & she will get it. She just hasn't figured out what you expect of her.
If you catch her in the act in the house and with this method other than when you have her in her spot because you can't keep 100% eyes on her ~ you should see this every time, Interrupt her (No! Potty Outside (be stern)and take her immediately outside. When she finishes ~ love her up.
Clean the area she dribbled on & make a note to self keep all eyes on her all the time when she has free run.
If you find a "treasure" after the fact or wet area ~ don't fuss at her ~ it wasn't her it was because the person keeping their eyes on her took their eyes off of her and allowed her to go potty in the house. After the fact scolding won't help anything ~ she'll just get sneakier.
Hope this helps. Keep us posted. First dogs are really when you just start to learn what methods work for how you are ~ frustrating but fun once you get passed this major hurdle & you'll be on cloud 9 ~ so proud and enjoy her so much more once you start working with her, instead of feeling like she just isn't getting it. She will get it
