Plate V. The heart and chief blood vessels of the horse. 1908.


I know this is annoying, but I’m trying to make some money to pay for school stuff. I’m selling a bunch of stuff on eBay including a 52” leather girth and leather Vienna lunge reins. The girth is up for auction right now starting at $0.99!

So if you’re interested, take a look.

Thank you!


Awesome times at the lab today.

Horse fetus. 1886.


Stomach and bowels of the horse. The Modern Horse Doctor.1886.


The vet was at the stables today for the monthly rounds and taught me an easy way to help diagnose lameness in the front feet.

When the horse is trotting, it will bob its head up and down. It will go down on the sound foot. Therefore the other foot is lame!
