Save the dog from a 70m deep, 35cm wide hole

A real-life engineering problem.

In Turkey, a 3 months-old dog has fallen into a 70 m deep 30 cm wide hole and it's been there for 10 days. People and local government organizations are still trying to save the dog. It is still under 70m deep borehole in Istanbul.

According to tweets, local government branches of saving, rescuing, mining organizations are also trying to save the dog. They still need for more practical ideas.

Here are some information I gathered from tweets of Baris Sengun of Animal Rights Confederation.

Some info: the puppy is 3 months-old Kangal breed. They have considered to dig another hole in parallel. Since the soil is soft and muddy, they've been said it might cause landslide. The dog should't get weight but they normally get 1-1.5 kgs per week. So they feed it under control. They tried nets but it did not fit as it needs to.

Any ideas?

It reminds me of The Crow and the Pitcher from Aesop's Fables: https://en.wikipedia.org/wiki/The_Crow_and_the_Pitcher

Without knowing the total parameters of what is possible and not possible, perhaps they could slowly lower buckets of dirt and rocks to the bottom in a way where the dog could just remain standing on the top of the pile.

wire cage just below the diameter of the home, 3 to 4 feet tall so dog can stand up in it, large cable to hoist it attached at the top, install a canvas cinch sack, with grommets in the bottom, completely open on bottom when lowering, run a smaller rope through the grommets, with the grommets low to the ground on the cage.

Also need a light and webcam or remote cam.

Hang dog treats on top of the cage.

Then Lower the cage with the large cable till it's flush on the ground, watch on camera for dog climbing up for treats.

Then pull small cable to cinch the bag under him.

Hope they get the little guy out.

Fill the hole with water on a pipe that's lowered to the bottom (so the dog does not get a shower for hours).

Because 70 meters isn't challenging enough?
