My Coidy has had this problem since she was 1 year old. It started shortly after her spaying, and as you say, it is homone related. As you described, she would awake from a nap only to have left behind a large puddle of pee

She has good control with 50mg. of Proin 50 (Phenylpropanolamine hcl) twice daily. DES (diethylstilbesterol) is another commonly prescribed drug.

Hopefully your dear Buddy will get good relief from one or a combo. of these two drugs...and you're not alone! Many doggies have this problem and have good results with drug therapy.

Let us know how it goes at the vets

P.S...Buddy is precious!!
