We made it to Haines, AK yesterday (July 20th) and have had no problems yet. Everyone is very nice and Canada at least seems very dog friendly. No dogs on beaches seems common, but the further into the heart of the country, the less people seem to care or enforce the rule. I would say if you are responsible and keep your dog under your control and clean up after them, you won't run into any problems either. Having a great trip. My eyeballs are worn out from staring at non stop gorgeous scenery the whole way. Things could be worse!
