The caster can try three times to summon three different types of animals. For example, a caster first tries to summon wild dogs to no avail, then unsuccessfully tries to call hawks, and finally calls wild horses that may or may not be within summoning range. The DM must determine the chance of a summoned animal type being within the range of the spell.
So, if the 1st caster is the first to summon the animal in question, then I take the spell's description to mean that the 2nd caster is unsuccessful as no animals of that type were available. The spell goes on to state:

The animals summoned aid the caster by whatever means they possess, staying until a fight is over, a specific mission is finished, the caster is safe, he sends them away, etc.
I take this to mean that there would be no competition... The animal is simply unavailable until the 1st caster no longer needs that animal.
That being said, if both casters were to somehow begin casting, as well as finishing the spell at exactly the same moment, then I would have both casters make a spellcraft check and the caster that rolled the lowest "wins" the "spell battle".
