I agree with tianimalz, the only part of that video that bothered me was them getting
on her at such a young age.
So many things can be taken completely out of context, especially in regards to photos. Depending on the temperament of the foal and how much previous handling (or mishandling) she'd had, she might have had issues that needed to be corrected NOW, while she's still small enough to not really be able to truly hurt someone. The biggest thing is, we can't
know because we weren't
there.
As for the whole bit on a baby thing, I must be a horrible abusive asshat too because my guy was a grand total of 6 months the first time he wore a bit and was asked to give to the pressure of it. And worse, it was a single jointed snaffle *gasp*.
It really bothers me when someone tries to trash a trainer's or an owner's reputation by flailing their arms and shreiking "ABUSEABUSEABUSE!!!" just based on a few pictures or a short snippet of video, especially when the abuse isn't blatent; by blatent, I mean beating a horse with a board/chain, doing something to purposefully draw blood or cause permananent injury, etc (the first thing that comes to my mind is the photos of the stallion in south america that was left in his stall with twine tied around his lower jaw that kept it tied to his chest to "encourage" his tucked headset).
If you don't agree with the training methods shown, then simply state "Wow, you know, I really don't agree with how this was handled or what these folks are doing", but to scream ABUSE when the filly clearly hasn't been horribly injured or terrorized is just attention-mongering. Other than being a little sweaty (which, by the way, both of my foals would run themselves into a lather for the
fun of it at that age), this filly has zero signs of even being worked other than a relaxed body carriage and a respectful look.
