They are just different degrees of the same thing. Tenderness is 'a little touchy' and may have some swelling or puffiness. Lameness is beyond a little touchy, where the horse is obviously favoring a certain foot or leg. Lameness is usually more easily observed at the trot, and will help you locate the exact leg or hoof where the trouble is.
I find that lameness is when something (example: a horse) is disabled so that walking is hard to do or cannot be done. Unsoundness, however, is being weak or infirm. Many people think lameness and unsoundness are the same, but they're not.
A visit by a vet or a farrier.
The difference between a horse is about three feet.
You can detected lameness from a horse because its back legs should be staright not floppy it should not be nappy it shouldn't have puss in its eye and it should not have a skinny belly
The word would be "sound".
Lameness, especially when a horse is turning in circles; shifting lameness when standing. Heat in the feet. Increased digital pulse in the feet (most easily palpable over either sesamoid bone at the level of the fetlock).
It is an exostosis (spur or bony outgrowth)on the pastern bones of the horse, usually causing lameness.
One way to tell is, obviously, if they are limping or showing signs of stress when they put weight on the leg. Another is if there is heat, swelling, or tenderness anywhere in the leg or hoof. Also, if a usually active horse is not moving, or only doing so reluctantly, it is a good idea to get a vet check.
INSTINCT!
A horse in an animal... Horse radish is a plant you can eat...
There is only one huge difference between an equestrian statue and a horse statue. An equestrian statue is a statue of a rider on the back of a horse, while a horse statue is just simply a statue of a horse.
It could be a hoof abscess, or another type of injury, or laminitis. Lameness can be serious...have a vet look at the horse.
