I remember fishing a perch tournament on Mission Lake in-front of the ski hill. We were not to far out from shore but I sure found the tullibees. I was not really catching the intended perch but still it was good fun. Like the other have said I was about midway between the ice and the bottom. I would lower my lure to the bottom shake it for a while turn the reel 3-4 turns shake it for a bit and continue this all the way up.
Not sure where to go for dog, but where ever you find the perch or tullibees they won't be far behind. Just lower you lure to 6 inches of the bottom. Sometimes even banging it on the bottom a couple of times and stirring up the mud or sand is good to.
The medium to smaller tullibees make good pike and burbot/dog fish bait just make sure they are not alive.
