Getting the dog back is even easier. You simply get a vet certificate here in Belize which is around $35 US. Entering the states through customs takes around 2 minutes and you simply hand them the certificate (if they even remember to ask for it, twice they've not asked me for it and we just walk through and enter)

Thanks for your reply. Leaving tomorrow and he has to stay behind this trip, but hope to work it out next time.
