It is the most known and preferred method around the world. It can be described as an inverted cone placed to the head of the patient. The patient has to live with this cone during the recovery period. However, even the most peaceful patients cannot adapt this apparatus not later than a few days. Many patients insistently want to take this apparatus out and thus, insist on. The use of this apparatus for 30 kg and over patients is usually problematic and it breaks frequently. If the patient is skillful, it can remove the apparatus. For the injuries on the forepaws, it generally does not work. Some of the patients try to scratch their wounds with their paws despite the collar and the wounds under the abdomen may also need to be put dressing sutures and bandaged against the risk of herniation and infection. Apart from these, the patient often scratches the head and neck region with its paws due to the discomfort given by the Elizabethan Collar. In this area, injuries and dermatitis may occur together with irritation. Long adaptation period is a reason for stress in the patient. The recovery process usually prolongs as the body’s resistance is lost and the diet is irregular due to depression.
