Domineque, it looks like you have enough root structure left that your plant will be fine. Sans are remarkably resilient! I would repot in in a proper soil mixture for Sans, very high drainage, and be mindful of its watering schedule.

Can I buy that like at Walmart or do I buy online?

Do you have a local poultry farm?

Some building and roofing suppliers have it too, as #5 crushed granite aggregate.

There are a lot of farms where I live so I should be able to find it. If not is there another option?

Perlite makes for great drainage. I use that. Other people in this forum say pumice is great. Your location in the country depends a lot on what's available. Try to use a cactus potting soil as well.

Crushed granite should be able to be found at any feed store.

I do that to them often on purpose, and give them room to roam. It makes new pups grow really fast! Repotting can be tricky because the roots shouldn't be put very deep, which can result in top-heavy, wobbly plants. Putting a few decent size rocks around the base of the plants can help keep them from falling over while they get re-rooted. Don't pack the soil tightly, leave as much air in it as possible. Watering gently the first few times can also help prevent unnecessary compaction.
