some questions

I will have more I'm sure:

Do I manually have to remove equipment off dying horses?
Does it get removed and put in my inventory when they die?
 
Do I have to manually create my arena shows every day?
Does it carry over and keep running the same shows until I change it?
 
Do the specific horse breeds lean toward a particular discipline?
ex: paints for western etc / or is it random rolled stats at creation?

I'm pretty sure tack gets removed automatically when your horse dies.

Shows need to be created every day. 

And all stats are random from the equine center no matter the breed to my understanding :)
