It is much the safest and best plan in such cases to at once summon the veterinarian, and not trust to yourself, as the veretin-arian's knowledge of anatomy and experience in operations of this kind enables him to perform it more readily, and with the least pain possible to the dog. If you are situated so that you cannot secure the veterinary, first examine and determine in what direction the bone is parted from its socket; for instance, in dislocation of the hip, the head of the thigh bone is generally carried upwards and backwards, this being apparent to the eye, as the injured side is thereby made higher and can readily be felt. Have an assistant to hold the dog around the loins steady in one position, while you take hold of the dislocated limb above the stifle joint, which will retract the thigh bone downward and forward. In similar operations you must be guided by the same principle. Rest will be needed for the patient, and violent exercise must not be allowed for some time. There is always a disposition to a repetition of a dislocation.
