My Shetland Mare was accidentally bred by an AQHA stallion?

I did not know that my Shetland was Prego until about 1 month ago when she started to bag up. Everyone kept saying that she looked prego but Sugar has always been on the pudgy side, so I did not pay it any mind. Plus we had just put them back out on pasture about a month prior, which is when the weight gain started. I have a AQHA Gelding(recently gelded) that I know is the only candidate for the father. Her now 2 year old son is still in tact but is not interested in girls yet nor was he anywhere near being ready a year ago. So my question is do I have anything to worry about being that my pony is about 12.4...maybe smaller and the sire is about 15.2. We live in a small town in GA and have vets but they are not terribly concerned about what I am asking..My vets answer to will she have problems was " we will have to wait and see". That is not very comforting! She has had one baby to my knowledge, maybe more but only one with me. No complications with 1st..had him on her own outside in the pasture at about 8 AM. When she was prego with Moon(1st) she was HUGE. She is about that same size now..maybe a touch smaller. I do not know when she id due as this was not a planned thing obviously. Should I be worried that she has had milk for a full month now? No change in milk color, has been clearish white the whole time.

Paint is my pony
Chestnut is the Stallion
I will upload some better pictures, but since they r about the same distance away you can see the difference in size.

If you think the 2 year old intact male isn't interested in mares yet, your not being honest with yourself. Just because you haven't seen him show any interest doesn't mean he hasn't or just not when your around. WHY was your pony mare even in with two male intact horses to begin with? Or is that not a correct assumption and somehow she got herself with foal? Oh, and it is PREGNANT..not prego..that is a spaghetti sauce...

The intact 2yo could have very well gotten her pregnant as well...

When was she first put out with the then intact AQHA gelding? Has she been housed with both the 2yo and the new gelding?

Why was she put in with intact males in the first place?

It says the 2 year is her son. Maybe he was just never weaned/separated.

It isn't too common for a foal to grow too big because of the sires size. I've know several people to breed 12-13 hand ponies to a 15.2 Andalusian stud. There were never any problems that I heard of.

Good luck either way!

Your vets answer may nor be comforting but it is the only answer to be given....the fact is that at this.point all you can do is wait and see.

Heather, your question is whether him being a full size horse and your mare being a pony can cause complications...?

I've know people who purposely bred large stallions to pony mares (don't ask me why) and the mares had no problems foaling. The foals seemed to conform to the size of the mare until after birth and then they grew like crazy.

Having said that .. as I'm sure you know .. ANY foaling can have complications and it is best to be prepared for that with any foal. I would not be overly concerned with baby-daddy size, but keep it in mind.

I hope your vets are more responsive should you need them in an emergency.

Oh, and get that young stallion away from mares .. he is definitely capable of doing the deed.

Hope it all goes well for you ..

Oh, and your pony is precious!

You can't really know. No pregnancy is going to be the same.

All you can do is wait.

Good luck with it and keep us updated!

Okay since everyone is jumping to conclusions...I STATED IT WAS AN ACCIDENT! Which means she was not housed with him but they do not get "pregnant" from air! Her son was a YEAR old at the time...he was weaned but they would be together from time to time....I am assuming that one weekend when I was away for work, her and my now gelding...gelded him so that this does not happen again...since you guys think I did this on purpose apparently...had a meeting that no one told me about. I asked for advice not criticism. You are the people who remind me why I "do not" post on these. Accidents happen and it did, now I am trying to do whats best for her...Piaffe thanks for being positive and actually reading!

My Quarter is gelded, I am waiting on her son until it cools off..don't want him having problems with bugs and flies. I don't have to worry right now as she is separated from everyone in individual turnout.
Thanks to all the positive help too..!
She seems to be a little more "jittery" the last few days..sometimes pacing the fenceline to the point where I have to bring her back in. She also seems to have more milk the last few days, no change in color but more milk.
