I have a pair of inflatables (low end Advanced Elements - no frame), a folding boat (Trak), and hard shell sea kayaks. Inflatables are slow as molasses and very much impacted by wind. The Trak acts like a sea kayak, but you need to be aware of extra safety issues (not just the risk of punctures, but also that you really need to use float bags and be aware of what it takes to drain the boat without bulkheads in a rescue).
If I was paddling coastal AK waters, my first choice would be the hard shell touring kayak. Second would be the Trak, and then I would limit myself some. If the inflatables was all I had, I'd find a pond or other protected water to explore. I would mot bring a dog on any of these.
Truthfully, you are trying to get a boat that will do everything, and that just doesn't exist. Neither inflatable boat you mentioned is one I would take on open ocean (even if you are on the somewhat protected inside passage). Carrying on a hike to a pond or small lake, probably fine.
Taking a dog on a kayak takes a bit of dog training and a special dog, doesn't work for everyone. I would lean toward a sit on top kayak as a way to take the dog for coastal paddles in somewhat protected areas (but not for open coast - AK has a reputation for some quick weather changes and extreme conditions).
