You have plenty of options here. How as a dog owner can your partner in good faith ship his dog as if he were a carton of books? The warnings which GatorGal listed are just the tip of the iceberg of why his dog must not be treated like parcel. Why give him the enormous stress and suffering? If you don't have the time to drive the dog as BoSoxFan45 mentioned, here is a review of what your fellow FTers have suggested
1. boilermaker: "Why don't you fly down, pick up the dog, and fly back? AS has some cheap fares, and even if the dog flies in the hold, you will be there checking it in and picking it up. Much less stressful than flying alone."
2. Boraxo: "How about finding a friend to fly up with the dog on a cheap weekend RT? This may be cheaper than cargo, which usually runs in excess of $150 RT plus vet health certificates (required by all airlines prior to transport)."
3. jenniferpa: "Personally, I'd rather Fedex my child (or my husband) before I'd Fedex my dog. Have you considered putting the dog into kennels until your boyfriend is ready to relocate?"
I'm not sure if david4455's idea is permissable on planes but if it is, you have yet a 4th option. You just cannot ship this dog. Please don't.
