Operational, to “feed that bulldog” could be to generate ample revenue to satisfy expenses.
If there’s a space between “bull” in addition to “dog”, I assume it suggests “feed dog towards the bull”.If there was clearly no breathing space, I guess it will mean “feed something on the bulldog”.
In organization terms it means to make plenty of income to satisfy or go over the expenses with the business.
It usually means feed the actual Bulldog.
Get some food along with feed the actual damn puppy.
