Question about Horse Behaviour & Your opinion?

Question
*I have READ THE NOTIFICATION*

Hello,

The other day I was in the arena to work on some training with a horse that wasn't handled for a while and I brought 3 horses into the arena so they could have a little run. I sat down at one point to have a rest and the three horses where loose in the arena like always. One of them was staring into his paddock and I looked and there was a deer in there and my horse started snorting and pawing and whinnying and running up and down the fence line, I found it funny and he wasn't being naughty. I was just wondering why he did this, was it because he saw the animal as a threat or was very curious?

Also what is your view on Rodeos, personally I do not like them however I'd like to know what you think.

thanks!

Answer
Hard to say what horse saw, could be he saw a fellow herd animal and wanted to go play. or saw what he could not make out and wanted to snot to warn or alert the rest of herd.

I did several videos on most all sports, not good for horse when winning, time, or speed is involved.
