My horse has a blueish-purple steak on his gums, is this bad?

I was researching horse gum colors and it said that blue-purple gums can indicate shock or poising, but it neglected to say whether this applied to a single gum color or any presence of the color. the rest of his gums are a normal plae pink, but near his back teeth it looks like a large vein, could this be what it is? please help, thank you

If the horse is going into shock or has major blood loss, the entire gum line will go blue/purple. To test, you do a CRT test or Capillary Refill Time. Lift up the lip and using your fingertip press hard on the gum. When you release the pressure, there will be a white spot left behind and you then count the time it takes to turn back to pink. 1 to 2 seconds is normal, 3 or over and there is a problem and you should then check temp, pulse and respiration and then contact your vet. When a horse has had a severe traumatic injury or really bad colic, you can lift the lip and immediately see that the gums are going blue and a vet should be called immediately. Your horse sounds like it's fine and that it's just a variation in gum color. However, knowing how to use the CRT test or visually seeing blue gums will help you in an emergency (hopefully you won't ever need it).

cuz like i have a dog who has a blueish tounge tht is polka dots but vetinirian said its fine but ask the veteninerian to make sure.....
Reply:When they're in shock it's all the pink tissue changing color, so don't worry about that.. what your boy has is normal, it's just a pigment change in the skin.
Reply:Your horse is fine if he's always had that streak. What you read was talking about if the gums suddenly changed colors. If he was in shock or poisoned, you'd also see other symptoms.
Reply:Look under your tounge and I bet you see the exact same thing that you are seeing in your horses mouth. Normal anatomy.
Reply:He could be dehydrated
Reply:probably normal but have it checked
Reply:How long has he had this. His gums should be flesh color.
