There has been an update on this procedure to allow dogs that originated in the USA to be returned from a country considered to be at high risk. However, you need to be careful to ensure full compliance:

1) Dogs vaccinated in the United States by a US-licensed veterinarian may re-enter the United States from a high-risk country without a CDC Dog Import Permit if the dog:
has a valid US-issued rabies vaccination certificate;
has proof of a microchip;
is at least 6 months old;
is healthy upon arrival; and
arrives at an approved port of entry
Expired US-issued rabies vaccination certificates will not be accepted. If the US-issued rabies vaccination certificate has expired, you must apply for a CDC Dog Import Permit, if eligible.

2) All dogs that have been in a high-risk country in the past 6 months may only enter the United States through an approved port of entry, which includes all 18 airports with a CDC quarantine station: Anchorage (ANC), Atlanta (ATL), Boston (BOS), Chicago (ORD), Dallas (DFW), Detroit (DTW), Honolulu (HNL), Houston (IAH), Los Angeles (LAX), Miami (MIA), Minneapolis (MSP), New York (JFK), Newark (EWR), Philadelphia (PHL), San Francisco (SFO), San Juan (SJU), Seattle (SEA), and Washington DC (IAD).
All dogs imported into the United States must be healthy on arrival.
