That sounds about right Dude
I'm paying about $2400 for 2 dogs (1 large 1 small) from LAX to Auckland and another $2500 for quarantine for them.
The vet costs do add up as you are supposed to have exams for them with each of the blood draws/microchip checks etc.
The titre will probably run you about $90ish, and vaccinations vary from vet to vet.
I had ISO chips put in my dogs (they now have american standard ships and international ones, ha ) and a lepto vaccine as the quarantine asked for it (though if you can get away with not doing it, do. )
