Inappropriate elimination is not a diagnosis but a description of a problem with a pet not going to the bathroom in the place where we want them to go. Sometimes it is a training problem. Melissa of Come Sit Stay in Sanford and Abby of Sandhills Dog Training in Southern Pines can certainly help you teach your dog appropriate potty habits.
However if your pet was previously house or litter trained, and is now not going to the appropriate place to urinate and/or defecate, that's often a MEDICAL problem. Cats urinating outside a litter box may have painful cystitis, an inflammation of the bladder- typically not an infection. Or they may feel blocked due to a personality conflict with another house hold pet. Or the box is more dirty than their liking due to them or another house hold cat urinating more often because of kidney disease or diabetes. Or they simply can't physically get into the box any more. Dogs may develop incontinence, or cognitive dysfunction, or a disease that causes them to urinate more often such as a urinary tract infection, kidney disease, diabetes, Cushings disease, or liver disease.
Poop accidents are also often due to a medical condition in both dogs and cats.
The point being, don't try to train a previously housebroken pet if they suddenly start urinating or defecating inappropriately. It's probably a medical issue that we can fix. And you won't have to worry about cleaning up messes any more!
