Presumably the vet has already ruled out an infection. An infection would be treated using anbiotics. A simple test of her urine for bacteria should be able to verify that they aren't called for.
Given it's a doberman and a female dog, I think there's a high chance of something called "spay incontinence". It sounds like your vet realises this and is acting appropriately. As the name implies, spay incontinence is a common side effect of being spayed, and is particularly common in Dobermans. It can develop years after the animal was spayed. Having the uterus removed may damage nerves, which is why the dog leaks without realising it.
Read here about non-surgery ways to treat spay incontinence. Mostly involving herbs and diet changes. Think carefully about this, the herb/ strict diet regime may not be as low risk as the web page makes out. I'd would confer with the vet before trying any of it.
Read here about one dog's treatment history when she developed spay incontinence. Note that the dog required 2 expensive and painful surgeries, and her incontinence was still not fully resolved after that. But the owners found the final very small leaks manageable, which was good enough for them.
