Propalin works brilliantly.You will probably find that you see an improvement in just a few days. My elderly labrador was put on it when she started constantly dribbling urine and it cured her even though she had to take it for the rest of her life. Propalin is a specialized drug so i dont think that the vet would have prescribed it if it wasnt needed. Is she elderly? apparently this type of problem is quite common in elderly bitches and bitches who have been spayed. My bess was both but i highly recommend the use of propalin as it made such an huge difference to my girl.
Good luck,i hope she shows improvement soon. Make sure your other pets dont eat some of her food though....
