Here's how the fight started: Sugar was in the little shelter where both horses were eating from. Ruby was half in just eating along with Sugar until Sugar wanted to get out. Ruby was blocking her so she tried getting Ruby to move out of her way. Ruby didn't want to move because she still wanted to eat so she stayed. Sugar then took it a step further and got upset, felt trapped and started kicking. She smashed holes in the wall, turned and kicked Ruby several times around her left abdomen and flank.
Ruby didn't have a lot of open wounds but she was a bit sore and she limped too. The vet showed me one way to tell how bad Ruby's injury was is by walking her around and then trotting her. If she didn't limp and show sign of soreness when she walked it wasn't too bad of an injury. They had her trot and I could see she was sore and uncomfortable. She didn't show much soreness walking as she did when trotting. If it was really bad when she walked, then it would be much worse than if she trotted.
He also checked her teeth as well. He pressed down on her gum with his finger, turning it white, and then he let go and counted in seconds until it turned pink again (blood flow). I think it was about two seconds until it turned it's normal pink color again. If Ruby had lost a lot of blood or hadn't had water then it would take longer until it turned pink again.
He looked for sore spots by pressing down at different parts of her body to see how she reacted. Then he checked her heart beat. He shaved away hair around two spots where she had open wounds and cleaned them. Then he put some creamy stuff which I don't remember the name of. He injected in two places (don't remember the name of the stuff sadly), one in a vein on her neck and another in a muscle on the rump. He showed me the first shot he did on her neck. He showed me the blood that he sucked a bit of in the tube to make sure he got the vein. The second shot he wanted to make sure he didn't get any blood because he wanted to get in the muscle and not a vein. He showed me that he was standing on one side of Ruby and injected the needle on the other side so if Ruby kicked out she would kick out at the needle on that side and not hit him. She was calm and good and didn't move when he did it. Some horses would though it it was better to be on the safe side (literally).
After that he showed me some medication to leave for Mrs. Davis to give Ruby. He also gave me brochures of different anatomy, medical and care of horses so I have that to read now!
Took this picture of Ruby a day before:
