I'd love to see what his heart looks like! I'll check with my vet and
see if he can do this. You think he may have a significantly larger left
ventricle? I've always wondered if his whole heart might be
proportionately large, and with that small body, just doesn't have to
beat as much. For a small horse, he's heavy. Is built like a tank. He
probably weighs close to what 15.1 Gavilan weighs...

I can also do hill work on both of them and note HR changes. It's not
science, but it's interesting. 

Kadance's HR amazed me because it's so much better than my other horses,
but he's a hot little jack rabbit... anxious and competitive. I would
expect his HR to be high because he's so excitable. Gav, on the other
hand is larger (15.1) and very easy (I ride him in a halter). We don't
go slow, but not fast either. He finished 2nd on his last ride carrying
a heavyweight, but it was a slow, cold, wet, ride and he's a frog in the
mud... he's a horse with 4 corners and a solid center... he didn't get
that 2nd by going fast. Gavilan is as steady as Kadance is volatile.

I'll let you know what, if anything, comes of this.

Happy Holidays!
