Trying to find reliable horse information on the internet can be both time-consuming and not very fruitful. It's also downright scary if you're looking up symptoms or health issues. (Which I mostly avoid dong because, well, I'm really enough of a worry-wort as it is.)
Sometimes you can find fun stuff, though, like your horse's pedigree online.
Oddly enough (or maybe not), if you go back a bit on both Lena's and Bar's pedigrees, you find Man O'War.
I actually don't care much about what genetics make up my two horses. Their personalities mean more to me than the bloodlines they came from, though I am glad they both inherited good confirmation.
