Your dog will need dinghy
access for shore trips, dock-to-ship access, too. I suggest engineering a fold up ramp
with non-skid, this might be stoved vertically against a bulkhead or in a hanging locker, or underneath the foot of a bunk, open. She will learn to use such a device rather easily. [I once taught a dog to climb a ladder.]
Good luck with it.
