The only thing I've ever been asked about was eggs and the US customs confiscated 3 of these. I understand dog food may be an issue but I don't have any pets, so wouldn't know. You'll have more issues entering Canada with food than entering the US. You can shop at Three Bears in Tok for food you need. Prices will be higher than in the US but cheaper than trying to stock up in Canada. If you get food in Canada it must be declared. We spend every other summer in Alaska and although food is more expensive it's not crippling. Read the Internet info on what you can and cannot bring. If your pet needs special medication or a special diet, I'm sure a prescription or letter from your vet will suffice. Milepost should be available at a good book store, or at a Camping World or Amazon with expedited delivery. An old copy will also work, as we replace ours evey 3 or 4 years.
