could she have an ulcer?

I'm wondering is my 13(14 this june)year old OTTB mare could have an ulcer, I can't afford to have an endoscopy done, but she is showing some signs. I got her at the end of May, and we started training in September/October. When I first got her she was kinda crazy, 2 weeks after I got her I tried to lead her out of the pasture for the first time(we have her and my 2 others on 24/7 turn out with a nice run in barn, we have feeders in there were we grain them) The first time I tried to lead her she kept running circles around me, dragging me and running into me, basically horrible ground manners, after that I decided she needed more time to adapt , so I just lead her around in the pasture working on keeping her our of my space and leading respectfully, when I finally found someone to help me with her we got her out of the pasture and next door(where they have a small riding arena) and we worked on leading over there and then lunging, after a few weeks she was finally acting lady like and we started under-saddle training, around that time I noticed that while she was eating she would kick at the wall behind her and bite the wood on the wall in front of her, but the donkey was on the other side of the wall behind her, and my old gelding in front of her, so I thought she was just been food aggressive. She was responding really well under saddle(she probably had had some formal training, but i'm not sure) She started doing some odd behaviors, she became girthy, biting at you when you girth her up and threatening to kick, and then when she was being ridden she would sometimes attempt to cow kick at you. She has also been harder to keep weight on. I haven't worked her since the end of November because of my trainer moving and the weather, but she is still being aggressive while eating...would she benefit to being put on an ulcer supplement or is she just acting up?

Bump, no one has any input?

I didnt think they were that expensive, think of it this way what if your mare had ulcers and you didn't get it checked out and you just started giving her a lot more food or tried her on all these expensive things which may or may not work when you could of spent $100 (not actually sure how much they cost) to get her checked out and possibly rule out anything else as well

It sounds like she might. My mare developed them entirely randomly (she was never stalled and only ate free choice hay) and her only symptoms were suddenly getting angry if I lightly touched her belly. I would be greeted with pinned ears and a cowkick. She also puffed up her stomach really big, which at the time I just figured was a hay belly. But the day I noticed her..it wasn't girthiness because I could cinch her up fine..it was more the middle of her belly. Anyway, I noticed the size difference in her belly.

If you can't afford scoping, is there a vet in your area that does acupuncture? Since I don't have a trailer and my vet's clinic is over an hour away, she used acupuncture to determine it was something with her stomach and with her kind of uptight personality, she said she wouldn't be surprised with ulcers.

She gave me medication for it and treated her for a month. Her big belly's gone. I can touch her stomach. She'll trot and lope without issue.

Does your mare throw a fit about trotting or loping? If they have ulcers, they don't like going faster because it sloshes around the acid in their stomach and is painful.

I don't have a trailer either and the vet hospital is probably an hour or so away, i've never been there so I don't know exactly how far it is, but I don't think they do acupuncture, there is a small animal clinic that I used to work for and one of the vets there does it, but I don't think she will work on horses, do you think putting her on this would help? U-Gard - Ulcer & Gastric Health Supplements from SmartPak Equine I haven't worked with her in a while, but sometime she wouldn't want to go and she would cow kick, but once she started going she would be good, I have noticed that in the pasture she is very lazy, I hardly ever see her trotting, even when we open the barn door and call her for her grain she just takes her time walking, she used to run in like a crazy psycho and you were always careful not to be in the middle of the door lol, I thought it was just because she was comfortable with her environment, but maybe that's because of an ulcer, Thanks for your help, normally I would call the vet and enquirer about the endoscopy (which I believe cost between 300-800 from what i've read online) but my boyfriend job has been slow and he's been having a lot of unpaid time off so we really just can't afford to spend that kinda of money right now, we are having trouble just paying the bills as it is
