Try to shove a very dry, very weak, sand cement mix down there about 25 to 1 should help stabilize it enough to top it from getting worse. I think the better course would be to remove all the old caulking, clean out all loose materials, install the foam insulator/depth material ( usually sold in rolls - can be precut to varing depths) , then pour in ( once mixed properly) the Deck-o-seal caulking. Follow the directions on the product ( which can be found at most pool stores) explicitly - in other words do not vary on the mfgr's instructions. If the mfgr calls for mixing the two products a & b for ten minutes - that does not mean 8 or 9 minutes. The key to a successful job to completion is proper perperation. This is not going to be a rush job so plan ahead. Do not start the job late in the afternoon or when it is going to rain. Best to do the job when temps will not exceed 75 or lows of below 50. When purchasing the product ask lots of questions about the product, preperation, cure time, working time etc.
There are three main types of inground swimming pools: concrete, vinyl and fiberglass. All of which are prone to the occasional crack. Luckily for the homeowner such cracks can be repaired. If you are handy you can purchase a do it yourself repair kit at your local pool specialty store.

You would have to hire a fiberglass pool repair company to do the several layers of reconstruction of a fiberglass pool. The "gelcoat" is part of the surfacing proceedure and can not be purchased in a store or wholesale wharehouse.
Remove the old damaged liner and install a new one.
Vinyl liner pools normally develop holes from some type of abuse, usually something is poked, jabbed, stepped on or scraped causing a hole. On rare occasions a seam can split open. Chemical abuse is another cause. To repair, YOU may try a vinyl liner repair kit from your local pool store or YOU may call a swimming pool leak detection company in your area.
Fiberglass swimming pools are easier to maintain, repair, and are less costly to install.
While I suppose anything is possible, it is very highly unlikely and improbable. I have done swimming pool leak detection and repair on thousands of pools over many years and I have never seen a hole on the bottom of the deep end from a dog.
