Good for you. When these things happened they were meant to.
I know you are a previous dog owner but some advice if I may.
The rawhides, make sure they are FDA approved and sold as a food item.
The rawhide sold as chew toys can contain a lot of glue and other 'stuff" that is not really that healthy for them.
Pig Ears and cow hoofs are usually a better bet.
Anything that goes in her mouth comes from her bowl, never ever feed her even once from the table. She will not associate the dinner table with food for her and there is a good shot she will never beg table side.
Crates are a good thing, good call on that.
The patchy hair thing may be a zinc deficiency, regular drug store zinc vitamin supplements are fine.
