Will Propalin be any good for untrained ***** who pees in house?

As far as I know this is used for a dog with incontinence, best I can tell you is to keep her in your sight and start the potty training. This is coming from one "old" person who wants to say "thanks" for giving her a home.

The dog you are fostering has had a rough life, and is rightfully anxious. You cope with this with training. Not self-drugging her. You will have to undergo the process of house breaking, and encouraging calm behaviour while discouraging anxiety. If you do not know how, or don't want to bother doing this, please return the dog to the shelter. If you feel that she has a URI or otherwise, she needs to be seen by a vet first for proper diagnosis.

Edit: All I'm saying is self-administrating a drug to a dog that has not been diagnosed by a vet is not a good idea. Have her see a vet, and let them prescribe anything, if anything at all is needed.

That medication is only used for dogs with incontinence problems and from what you describe it sounds like this is more a case of an untrained dog as well as a dog with a confidence problem.

Double check the usage of that drug by going to www.google.com and typing in the medication.
