Thank you for the info :)
Here is a pic that I took last week. It's not fabulous but it gives you an idea :)
I am a little concerned about sending her back to the previous owner as I didn't 100% trust her and I'm not entirely sure she has been honest about how much experience she has had riding.
I also don't have a bill of sale so she could just end up keeping the horse. I made a few enquiries to send her to a breaker for a week to be re-educated and work on ground manners. I'd train her myself but I just don't have enough confidence and knowledge on my own. To be honest, she scares me a little and I think she knows it.
I don't want to lose her respect and never get it back as I know that will be worse off for the both of us in the future.
Her someone with experience checked the saddle fit? If you haven't ridden in it how do you know it fits?
Her weight is just fine. Please do some research as overfeeding can be as much of an issue as underfeeding. After weaning and work she will lose the belly and gain muscle tone which is all she needs. She doesn't need to gain anything significant for sure and I think good quality feed and exercise will make her gorgeous. I definitely don't feel she's in "poor" condition as is, just average and optimal is always the goal right ;) Wait until the foal is weaned and she gets back from the trainers. I definitely wouldn't worry about overworking her in regards to her weight. Go slow as she is out of shape but health wise she looks ready for anything.
(Did you get a PPE to confirm that?)
She almost looks a little too heavy in the pic but hard to tell.
Overfeeding a pony can have even larger consequences as they are typically airferns and very sensitive to food (as in look at food get fat) and too much richness can cause very big issues. Henneke horse body condition scoring system - Wikipedia, the free encyclopedia
4.5-5 is typically ideal. Topline (unless the horse is very thin) has nothing to do with weight anyways.
If you don't trust her don't send her back, I'd be a little worried too.
DO get a bill of sale! Asap! There is no reason you shouldn't have one. Say your vet wants to see it or something if she's being difficult (and if she's difficult no you shouldn't trust her) That's for your own safety whether with her or another trainer or a bad situation where you need proof.
I'm glad you're being honest and sending her out for a bit. I'm concerned that "she scares me a bit and I think she knows it" I guarantee she DOES know it and trust me it's MUCH more likely she will misbehave knowing that. You need to suck it up and swallow that fear when working with her, do what you need to do before hand to get in the right mindset. I know that's easier said than done, but it's very important. You want a horse to do ANYTHING positive or negative you just need to think about it strongly and they will do it.. It also probably makes her nervous too. When the foal leaves will be a big test. Hopefully she's one in a million and won't take advantage but remember all the big stuff has small warning signs so don't let her get away with stuff.
Unfortunately while sending her out and getting a refresher is a great idea it won't do anything for the two of you and her respect with you.
DO find a trainer who will work with you, give her a refresher (make sure you find someone who can ride her as most adults can't, that will be the hard part) and have YOU involved with the training to boost your confidence and to help the two of you get the right start. I think this will make a huge difference and is very important.
Ideally you would find someone you could do tuneups/lessons with as well.
She's very cute. Even if she's been as good as gold in her mind she is not and that's an issue. I am seeing "owner issues" here (not meant in a mean way!) and that the horse hasn't done anything. Keep it that way while you work on your own confidence.
