Pet hair shavers should be used with caution for local shaving after surgery. This type of shaving device is mainly designed for daily hair trimming of pets. Although it can complete the shaving action, it has limitations: firstly, medical scenarios have strict requirements for disinfection and sterilization of equipment, and ordinary shaving devices may not meet medical hygiene standards, posing a risk of infection; Secondly, postoperative local shaving requires precise operation to avoid stimulating the surgical incision or damaging the skin, while ordinary shavers lack professional protective design, which may exacerbate skin sensitivity; Finally, some pets may have fragile skin after surgery, and the vibration or blade contact of the shaver may cause discomfort. It is recommended to choose professional equipment such as medical grade electric skin preparation knives, whose blade design, hygiene standards, and operational safety are more suitable for postoperative nursing needs. If using a regular shaver, it is necessary to thoroughly disinfect it in advance and operate it under the guidance of a veterinarian.
