I am a druid in a game. We are tasked with bringing down a keep's defenses for a army. Since I am a druid I figured why not get the animals to help me out. The only time I have ever seen handle animal used is when they are a mount or familiar, so I am not exactly sure what is and isnt allowed.
Since I am not taking a week to train a single animal, I will be using the push aspect of handle animal which has a DC of 25. Would having animals like large predator birds and bears attack the keep be a valid use of the skill? There is also no mention of what kind of action using push is.
Edit: As the comments moved to chat say, yes it is the inhabitants of the keep that are to be attacked and not the structure itself.

Handle Animal explains the type of action used:
For your druid, pushing (forcing the animal to do a trick it doesnt know) your own animal companion is a Move Action, while other animals would be a Full-Round Action.
Attack the keep! doesn't sound like a possible command by the rules-as-written, as none of the tricks available allow you to point the animal at objects or locations to attack. At best, you would have to make one animal attack a specific creature using the Attack trick, while others protect them using the Defend trick.
