I have two horses. And the more horses that belong to other people that I can ride, the better!
Because I have the eventual aim of being a professional horse trainer, and the more different issues I know how to handle, the closer I get to that goal. [edit; my gelding gets jealous, and it really is "HEY THAT'S MY PERSON LEAVE HER ALONE" - I don't give treats - but my filly really couldn't care less because the whole time she's been broke, she's had to deal with the fact that I do have another horse to ride]
Of my two I have the bipolar gelding who literally can switch from dead slow and sluggish HUGE flying kick every stride to keep him moving lazy to just about bolting forward in a heartbeat. He is a challenge but a lot of fun! And then I have the very smart, very sensitive, cold-backed breaker filly. They couldn't be any more different in how they move or how they need to be handled - gelding needs a very dominant, occasionally rough approach [he ALWAYS has the option to respond to a light aid before I get rough] and filly needs softly, softly, sweetness and light.
Both can be difficult travellers. My gelding is good to load [but WAS absolutely impossible due to the trip that caused his ongoing issues, I had to fix the loading thing] and will on the odd occasion self-load, but scrambles. My filly is just a nightmare to get onto the trailer, then she travels ok until you stop [at traffic lights, to get gas, whatever]. She doesn't back off easy either. She basically just needs a huge amount of positive trailer experience, because she doesn't have much experience at all and what she DOES have has been forceful... she CANNOT be forced.
I'm also presently dealing with owner expectations, being that I'm trimming my neighbour's horses' feet [I'm the only halfway decent trimmer she knows, I volunteered to do it for free because of the state of their feet but she's insisting on paying me], and a friend who has one of her horses on box rest in my "barn" is on my case to be her "farrier"... slowly collecting clients I haven't even gone looking for... must be doing something right with my horses' feet!
