Hello! This additional information is helpful!
Dogs develop a "Substrate Attachment" in regards XXXXX XXXXX
This means that what she was trained to view as a "potty" place has been imprinted on her brain at a young age. Apartment-dwelling dogs are generally walked on pavement for elimination purposes...this imprints paved surfaces as the place to "go".
***Changing this behavior can take some time since this type of dog is also strongly discouraged during training from using grassed areas that belong to businesses and homeowners!***
It is more difficult to retrain this thought-pattern if she spends the majority of her time outside, isolated from your company. Dogs take their cues from the people they are most attached to...if you are not actively building a new relationship for her, she may be trying to "wait" for her previous owner to come and walk her!
Female dogs can exercise great restraint in keeping their living area clean...if she view the kennel as her "indoor" space, this will compound her confusion about eliminating on the ground.
Re-training outside potty habits in dogs is the same as house-training, so do try the following:
1) Begin regular training sessions for "sit", "down", "stay", etc. This gives you both time together so that she bonds to you and understands your positive language and body cues when she does well.
2) Spend the time you are home keeping her with you...if you are uncertain of her reliability in the house, use a leash and literally take her through your day. When you are doing an activity in a room, teach her to "lie down" in a chosen corner of the room. This activity reinforces your place as the Leader, and teaches her good indoor manners.
3) When you Know she need to go outside, lead her gently around the yard. Let her sniff the ground (it helps if you place some previous BMs on the grass where you want her to go). You may have to go in-and-out several times before she gets the idea. The idea is to teach her that she cannot be off-leash until her bladder is empty! If she doesn't "go" in about 5 minutes, go back inside and try again in 20 minutes.
4) Have a treat ready for her when she does what you want!
Remember: if she is needing to learn to "go" somewhere that she thinks is off-limits, there will be a good deal of anxiety for her to relearn this behavior. Be very patient and understanding!
***You may need to consider getting her a small group of paving stones and create an artificial sidewalk for her (say, 5x5 feet square)...this can be used at one end of her kennel area, for instance. Pavers will allow urine to flow down into the ground and allow you to easily find BMs for cleanup...she can also avoid her eliminations and feel "clean" about her home area.***
I hope these two suggestions give you some ideas about what you can try!
