Raitto Kennels for boarding your dogs in Salcha if you're being stationed at Eielson AFB. They're about 7 miles or so past the gate off Stringer Road and Old Valdez Trail. Very hard to find rentals that are okay with pets here. Your best bet might be the AHRN website if you're military/retired. I also think 3 Dog Night Hostel would be your other best bet, since they have a recreational dog team. They're at MP335 or so on the Richardson. IIRC, both places might have websites if you google them. Good luck!
