A lot of Meta spells would work if work you wanted to counter the spell, but at nine miles you would need to be using some alternate rules to allow Long Distance modifiers on spell casting. Things like Suspend Spell, Suspend Mana, Dispel Magic, Drain Mana, or Steal Spell might all work if close enough.

That said, if you aren't using Long Distance modifiers all of those above spells are useless. I think having your mage cast another instance of Beast Summoning might allow for a quick contest between the spells to see which caster the animals go toward. Either that or the animals will try to go in two separate directions at the same time and be rather irritable about the whole thing.
