The medication Logan speaks of is DES. My vet still carrys it, though it is hard to come by. For the most part, it has now been replaced by the medication phenylpropanolamine, which has been found to be far more effective with fewer adverse side effects. My Cody, who developed this "leaking" problem at age 1 1/2 after spaying, is almost completely "controlled" with a twice daily dose. This drug, historically added to many cold meds., gained notoriety as of late as it was been found to be potentially toxic to humans. This has not been found to be the case in dogs, thankfully. Lots of prayers and well wishes for sweet Sara!!
