I think it’s when you are able to take care of a horse in everyday routine
Even more if the horse is at your home
One of the primordial thing is to be financially stable cause with horses you will always had something to buy
It’s also very important to be officer by someone who knows this wordl and could help you everytime you need it
I would say the right time is when you’re financially stable/have the finance to be able to take care of a horse and everything that comes with it, and when you’re positive you will be able to get the help you need if you need it.
