Your horse cannot speak, but he can certainly make you feel that there's something wrong with him in case he is suffering from something. If you suspect lameness in your horse, here are some points to check:
-Your horse cannot rest on one hind leg.
-He drops his head as the sound foot comes to the ground if he is lame in front and if he is lame behind, he reverses the process with his head.
-If he flinches or is inclined to rear up and finds it painful then he should undergo tests for shoulder lameness.
-Severe heat and pain in the foot, and bruised sole.
-Horn becomes sodden nd emits foul smell.
-There's a seedy toe on the wall of the foot, the larger it becomes, the horse feels more lame.
-The horse has broken pelvis, swollen legs, sprains, brittle feet, there's a crack in the wall of the hoof
