This is my horse. About 2 month ago I call nail man to cut his nails. This man was new to this job . My old man was bussy and my friend advice me to call him to nail the horses. He come and cut the nails but he cut them deep I think because horse get sick and can not walk operly and you can see he is in pain while walking. Most of the time he is lalying on ground because of the pain. I call vet. He come and give me the blue powder to mix it hot water and put horse nails in it. As well as the medicines that you can see the pictures. I did this but did not work. Vets in here no have knowlage about big animals. I call the old nail man and he come too he said horse get bacteria in his body so his legs hot. He suggested same medicines. We even nail the horse forone month so his nails grow proper. Today I clean his nails again. His nails as you will see the white places on nail is soft and it come out so easy. The rest of his nails are strong but the white places are so soft. I do not know what to do. Please help me to help this little horse.
