Hi, ive just read all the replies so far to this posting and agree with every thing thats been said. I bought a new horse a couple of months ago and she was described as being 100% bombproof etc etc. I paid alot for her to get what i thought would be the perfect first horse ( if one exists!) . I did everything i could think of to safeguard my purchase, got an experienced friend to ride her, rode her myself at different times of day etc and got her vetted. Then i got her home...hmmm. She had been in the same home fo 6 years and took ages to settle down. In the end i moved yards after just one month and i was seriously worried that i had bitten off more than i could handle. She was flighty, spooky, unpredictable and very stressed.
Thankfully, due to a great new yard owner and a strict diet plus loads of exercise we are slimmer fitter and infinately calmer two months down the line. I put her on Magic, a calming supplement just to help her chill out a bit and we concentrated on having lots of long stress free rides and getting back to enjoying it again. I m afraid had i been hospitalised as you have then the horse wouldve been sent packing by now. There is only so much behaviour you can blame on the stress of moving home etc and you either need professional help or take the choke and pack his bags before he does some damage.
Best of luck either way.
