So my daughter will be coming home in a few months. She had two pitbull/ mix dogs. Any suggestions on trying to get them home?

Have her take the dogs to the vet where she is to get them ready for airport release. They need a rabies vaccine and a rabies TITER test. Not sure if you have enough time though since it can take anywhere from 3-6 months depending on the results of the TITER test. If she doesn't get that they will have to go to quarantine. This way you can bring them home with you the day they arrive. Www.hdoa.hawaii.gov/ai/aqs/aqs-info

plan at least 6 months, preferably longer to get everything done.  Unless you are military, also plan to spend about $1000 per dog for the whole process.  You know how politicians like waiting periods.  we there is a lot of waiting that needs to be done between vaccines and testing. 

Also, consider shopping around for the titer test if you have that option.  I paid $400 per dog for that one test (only one lab in the US does it).  But the cost of the lab is about $80.  So my vet charged me $400 for collecting an $80 test.   

I can recommend a vet on the Big Island if they are coming here (you need to hire a vet to meet the dogs at the airport to make sure after 6 months, 2 vaccines and a blood test that they still dont have rabies)

Avoid quarantine at all costs. I came to Oahu with a dog & cat before there were any other options. Had I known what quarantine would do to them, I would have opted to give them away. It's torture for the animals, and torture for the owners when visiting and having to leave them day after day.

Neither animal was the same after that.

If you need to leave the pets with someone on the mainland after the daughter arrives in order to complete the tests and avoid quarantine, do it.
