my bottlebush was affected by an unusually heavy freeze this winter. The leaves are a grey (ish) color and some a brown. Is it possible to generate regrowth of leaves by pruning away the apparent dead growth or will they just naturally regenerate new leaves? Thank you.
If the freeze lasted more than a day or two, the branch may have died. Often an injured plant will push out new leaves in a few weeks. I would fertilize it lightly - about half the usual strength - and wait to see what happens when temps return to normal. Tips of branches are most at risk and you may need to trim them back. If you scratch the bark gently, you should see green underneath it. This thin green ring just under the bark is where all the water and nutrients flow. The center of a young branch should be white or off-white. If it isn't, and there is no green ring, the branch is dead at that point. Keep cutting back until you reach healthy-looking ring and pith (center). There are several plants commonly referred to as bottlebrush. I assumed that you are referring to Callistemon.
Moved recently and trying to identify plants and trees in the backyard to figure out if we should keep/transplant. Thanks in advance for any insight!

I believe that your plant/tree is a "bottle brush". More specifically I think its a weeping bottle brush, Callistemon viminalis.
You will know for sure soon enough when those flower buds open and display this plants unique beauty.

My dwarf bottlebrush froze on the outer limbs. How do I prune it effectively?
Frost will not damage the plant. This shrub needs to be pruned correctly in spring, once the weather remains above freezing. This article will guide you on correct pruning of these: https://www.gardeningknowhow.com/ornamental/shrubs/bottlebrush/pruning-bottlebrush-plants.htm
main stem. My bottle brush (Callistemon) is approximately 8 years old and about 5 feet tall and 4 feet spread. It looks like it's dying as the root isn't steady in the ground. Our soil (in Cornwall) is not great and mainly old mining waste. We weren't sure what to do with it, but yesterday I see that a new shoot, approx 3 inches tall, is growing at the bottom. If I can't save the main tree, would I be able to grow a new one from this shoot?
Yes it's possible to water and fertilize to cultivate the new shoot. But be aware that if it originates from the same unstable root system it may become unstable in time as well.
Without a photo it's hard to visualize what you mean by "the root isn't steady in the ground". Or why exactly it is dying. Is the plant wind-blown and uprooted? Are you watering adequately? You may need to work on establishing stability with staking of the plant, soil improvement and water management, before you can hope for any plant to grow well.
we live in Charleston SC our bottle brush tree was hit with cold this winter and all the leaves our brown. How do I know if the tree will survive ?
Temporary cold may kill leaves but not the tree. It is hardier and has a sturdy root system that is protected from cold, above-ground air. Small twigs may die. You can check by lightly scratching the bark. If there is a nice green layer under it, that's great. If it is medium brown, it's dead. Trim off dead twigs and brown leaves. You will soon see new leaf buds. I would give your tree some nitrogen to help it deal with this setback.

Are the flowering from the bottle bush poison to dogs?
These are, typically, regarded as non-toxic to dogs. I wouldn't worry too much about it.
