Hello, thanks for using Just Answer.
My name is Rebecca. I am a veterinarian and will do my best to help.
Is Jessie still getting steroids? That can cause a dog to produce more urine, and to leak urine.
Increased thirst can cause urine leaking. If the dog is drinking more that makes more urine and in older dogs that can cause urine leakage. So I would try to discover why she is drinking more. How long ago were the blood tests done? It would help to see them, to see which (there are more than a few) liver enzymes were raised, what the kidney numbers and the albumin number was.
The urinalysis results would also interest me: what was the concentration/specific gravity? Was there any protein, even a trace, in the urine?
The things that cause increased drinking do not all show up on a basic blood panel. Cushing's disease (hormone dysfunction of adrenals and usually pituitary gland) can cause increased thirst and urine leaking, but a basic blood panel may not tell anything about adrenal function. All you might see is an elevated liver enzyme called Alk Phos, or SAP, or ALKP.
A condition called DI, diabetes insipidus (not the diabetes that needs insulin, that is diabetes mellitus) can cause this kind of urine leakage, from an inablility to concentrate the urine resulting in a large volume of very dilute urine. This will not show up on any normal blood tests. There are multiple causes of DI.
I would be curious to know her blood calcium level; high calcium can cause increased thirst.
The best way to proceed is to find out why she is drinking more, and that means more testing. I would not limit her water, she may need to drink more even though it results in her leaking urine.
I am cautious using propalin in older dogs; there can be a small risk of stroke from increased blood pressure.
Let me know what other questions I can answer.
