1. Long cable with a pinhole camera to "see" 2. Another long metal cable with a "loop" at the end to grab the dog. 3. Aneasthetic gas to temporarily put the dog into slumber so that the extraction is not stressful.

Send a cable with a camera along with an "extractor" (which can grab the dog by its body.)

Slowly fill the hole with very salty water. The dog will float to the surface.

The stated dimensions will require about 7000 gallons of water. This is the capacity of a large-ish tank truck. 70+ meter hoses should be readily available.

Presumably warm extremely-salty water, or it might get hypothermic.

However, if it's somehow wedged in there, the dog could drown.

helicopter + dude on a rope

Not sure what you need a helicopter for... The hole is too narrow for an adult "dude". A kid on a rope could work. Maybe.

"Any old winch would have worked but we decided to go with the helicopter for flare."

1. Dig a parallel hole adjacent to the existing one (w/ a large diameter). 2. Then lower a person to the level of the dog (this person should have oxygen support). 3. Person then connects two holes by demolishing thin layer between these two holes. 4. Person rescues dog

I think you need to get a camera down there to monitor the progress of the solution

It's a dirt hole. My guess is that you create a large amount of mud at the bottom of the hole and then the walls collapse.
