I adopted my girl January 7th of this year and she had put on a lot of weight already, still needed more but she had only been in foster for about three months. I knew she was going to need some more help gaining weight and all her training. It has been a long and sometimes frustrating road to where we are now. She was pretty crazy, she is an Arab afterall. Spooked at everything, would run you over and basically just hard to handle. She is now the best horse ever. Calm as can be and will do anything I ask of her.
And just when you think everything is going good, something happens. She is losing weight, in the summer, on 30-40 lbs of good hay a day. She is still her same self with never ending energy but looks like she could take a nap any minute. Vet comes out tomorrow for an exam and most likely blood work.
So I guess what I am trying to say is before anyone takes on a rescue make sure you are prepared for a lot of work. Not just training but in vet bills too. I have seen my horse every single day since I adopted her. And those first few months were cruicial in trust and overall training. A true rescue is not for someone who just wants a cute little horsey, they take work and money and lots of it. Always make sure you have a good vet available and are willing to pay for them. No one wants to spend money but sometimes you just have to.
