Better be careful with how hard you push. Dobermans are viewed as an agressive breed by many (even though we had two growing up and they were both just big babies). The "any other dog or breed deemed agressive" my come back to bite you in the butt.
If the dog was on the original app or any alteration since then, and they have taken a deposit, they are pretty well screwed for accepting the breed. My wife and I have been there with this on the losing end. From our dealings, the writer of the contract is considered the expert, and by not specifying all dangerous breeds it leaves it open to interpretation on a case by case basis for any non listed breed. All our contracts now specify which breeds are considered "dangerous."
The one thing to make sure of is that you are carrying specific insurance for your dobey. There are 12 breeds considered aggressive from insurance companies and dobeys are on the list. They could get you out for not having proper insurance and placing the complex in a liability situation.
