Sara's dribbling is somehow caused from her spay (I can't remember how the vet explained it). I mention that because I honestly don't know if these are female/estrogen-type drugs or ?? Like K&O's mom said, I think the DES one is.
Sara's on a combination of diethylstilbestrol (1x a week) and pronin plus (phenylpropanolamine - 2x a day). I really don't know much about the meds other than the diethylstilbestrol is one that they DON'T want to up the dosage on because it can cause anemia and something else. I can say that since she's been on the meds, her dribbling has COMPLETELY cleared up. However, if we miss a pill, she dribbles so it's pretty imperative to give it to her on time.
I don't feel like I was much help. :(
If you have other questions, ask and I'll make my mom answer! lol
