Taking dog to alaska from NY...food questions

Thanks all. She usually eats raw food that I make but not bothering with that with border changes. I can convert her about a week before trip (to say honest kitchen dehydrated), bring enough for usa part. Buy more in canada enough to hopefully use up and not throw out. Hit up anchorage/fairbanks for hopefully enough to last most of the trip (3 months?). I can make phone calls to see what they carry. Hopefully that will do it for us.
