Hate to be a naysayer, but unless ya have extensive experience I'd take a small trip, 100 miles of so and go from there. Thats a looooong trip youre planning.
Logistics are hell on canoe trips. Restocks are rarely convenient. Dog sounds like a bad idea. Alot of rafting/canoeing deaths this year in CO, everythings swelled up from a big winter.
Spend a couple days out and then go back to planning.
But that's just my opinion, and I've never planned a canoe trip of that length. If your successful post your knowledge so we can copy it.
