Curval, it's going to be OK.
I just talked to my Labrador partner Vet in Atlanta and my local vet here in KC.
Both of them say two shots is no problem. Rabies is a "killed virus" shot, not an "active" shot.
The pup should get one shot now at 12 weeks (and Jason may have done this, I don't know) and then it can have a booster 3 weeks later.
So if you're coming mid-September and everyone gets off their butt, this is still do-able. One shot now (if she hasn't had one already) and one shot in three weeks.
My partner also pointed this out:
an original of a health certificate issued by a licensed veterinarian of the country from which the animal is coming to Bermuda
You need to ask your local authority if this means a UNITED STATES Federally licensed vet or if a STATE OF KANSAS licensed vet can fill out the health form.
It's all doable, but we'll have to find a local "Federal" vet if that's what they want. Most of these guys are just State of Kansas as the Federal certification involves a class, a test and money. There's just not that much call for it. But we'll find one if we need one. Heck my buddy in ATL is Federally Licensed.

I'm sure we can work SOMETHING out.
