My name is***** and I am sorry to hear that Annie is having inappropriate urination. It is NOT time to euthanize her just because she is having trouble holding her bladder.
First, did your regular vet perform a urinalysis to see if she has a bladder infection or potentially diabetes?
Second, did they do blood work to ensure that she doesn't have kidney disease, diabetes or Cushings?
All of these problems can make it very difficult for a dog to hold their bladder because they are making so much urine. All but the kidney disease are very treatable and treatment can greatly reduce the amount of urine the dog produces.
Next, what pills did your regular vet send home to help her control her bladder? Proin (phenylpropanolamine) is often the first choice that is sent home for incontinence but it only works about 75% of the time. This drug increases muscle tone to the urethra. If this doesn't work, we move up to estrogen supplementation. Estrogen increases the tone of the urethra much more than the Proin does. There are two different types on the market- Incurin and D.E.S.
If her blood work was completely normal and the urinalysis was clear, I would recommend trying the Incurin first. It also takes about 2-3 weeks to really start working well, so you have to be a bit patient with it.
Best regards, ***** ***** this answer helps you.
