OK, got my answer and hopefully this will clear any conclusion. I received an attachment from the Texas USDA vet in Austin and it says the the APHIS 7001 is OPTIONAL
The documents needed by the Export desk:
1. We must have the original, “Veterinary Certificate for Domestic Dogs, Cats and Ferrets entering the European community for non-commercial movements (Regulation (EC) No 998-2003”. It must be signed and dated by a USDA Accredited Vet. The signature must be in a color other than the printed color; blue is acceptable.
2. A signed Rabies Vaccination certificate. (The rabies vaccine used must be an inactivated vaccine produced in accordance with OIE standards). State if it is a recombinant vaccination. The microchip number must be on all rabies certificates submitted.
3. The original, if available, of the FAVN.
4. A signed APHIS Form 7001. (Optional- possibly required by the airline).
It is recommended that you contact your airline and ask the following questions:
What paperwork do they want from you in order to get your pet on the plane?
From the date your veterinarian issued the certificate, how long is it good for? (The EU certificate is valid for 4 months after signature by your veterinarian, or until the date of expiry of the vaccination shown in Part IV, whichever is earlier). The airline may have time restrictions on the required document (for example 8-10 days from the date your vet signed).[/b]
So there you go. Check with your airline and ask if they need the APHIS 7001 or if your vet can just send along a note with the Third Country Certificate saying that your pet is fit to travel. This would save us around $150 and the unneeded headache of worrying about the 10 day validity.
