OK so for a little bit of background Ive decided that I would like to buy horses meant for slaughter (either from the feedlot or bidding against a KB), keep them for at least 1 month (quarantine period) & while I have them train them as necessary. Then when their ready I sell them under a strict contract. Those that are pro slaughter please keep your comments to yourself! Anyways Im buying one horse at a time so I can completely focus on them then the money from selling them goes into feed, buying another horse meant for slaughter, & into a new truck & trailer cus the ol 86 two horse straight doesnt work like it used to & I also need a bigger truck, but im more focusing on a new 16ft stock trailer because a lot of the horses I get will be mustangs right off the range, & theres no way they will load into such a small trailer easily (though I did take out the divider. Hopefully that will help.). Back in March I bought a yearling paint filly & she came off the range somewhere sorta halter broke & thats it. Since then she has been a fast learner & easy to work with...except when it comes to medical stuff xP. Anything vet related she immediately freaks out. Her one flaw is that even if she likes you she isnt a 100 trusting. The smallest thing tends to make her nervous. So shots forget it...even small cuts have been difficult to doctor. The moment she feels even a small amount of pain she refuses to cooperate. I get why, but its extremely frustrating. A few days ago she got a deep cut on her right should & even applying salve, well she tried to kick me once. Today I haltered her & got her in the round pen because the wound got covered in dirt & has a bunch of puss. I used iodine diluted in water & the moment I touched her she reared. What I did was reward her when I got the sponge or syringe on the wound then after a couple of gos let her lunge a few circles to calm down & think so she would realize it wasnt that bad but after a couple of times she actually started trying to bite me. Of course each time I scolded her, & other than that I was saying "easy" "GOOD girl" etc. Eventually I decided to end on the best note possible so instead of completely disinfecting it & applying salve I cheated & used purple coat on the area that was somewhat clean, which she responded to a LITTLE better, & I put everything away then scratched her neck (She LOVES it), talked to her, & started massaging sorta close to the wound. Then I took the halter off & gave her some hay. Ive decided to leave her in the round pen for now. I know she was only acting out because she is not comfortable with even a little pain at all & was afraid cuz of it, but im frustrated because I dont know how to teach her that what I was doing is a 100% evil & neither are shots or any other vet stuff. Got any ideas guys?
