Construction of kennels for meat dog breeding: \xd\ The establishment of kennels should be firm and durable, and must conform to the living habits and sanitary conditions of dogs. Each kennel should have a separate playground. The kennel is made of brick and cement, and the doors and windows can be made of steel and wood. The playground should be made of cement or concrete with a slight slope, which is convenient for drainage. The partition wall is surrounded by angle iron, steel pipe and barbed wire, which is firm and durable, prevents biting, and is convenient for cleaning, washing and disinfection. The area of the kennel depends on the purpose and the needs of the dog. The area should be no less than 1-12 square meters and the height should be no less than 2 meters, of which the dog room is 2-3 square meters. The bedroom for breeding bitches is 3 ~ 4 square meters. The living area of a puppy kennel shall not be less than 6 ~ 8 square meters because it lives in groups. In addition, the following issues should be paid attention to when building a kennel: \xd\ (1) Daylighting and ventilation: sunlight and ventilation are important conditions for the hygiene of a kennel, and the lighting window should be 1/8 ~ 1/5 of the area of a kennel bed, and glass windows should be installed to prevent mosquitoes in summer. Natural ventilation in the kennel is equipped with a special artificial ventilation device. \xd\ (2) Moisture prevention and drainage: Dogs hate moisture, so the establishment of kennels must pay attention to moisture prevention. The dog bed should be 2 ~ 3 cm above the ground. The kennel needs to have a large-diameter tap water pipe in order to flush the kennel with greater pressure. The sewer is preferably a large-diameter culvert. If it is an open ditch, the dog farms are not allowed to communicate with each other to prevent infectious diseases and parasitic diseases. \xd\ (3) heatstroke prevention and heat preservation: the standard temperature of kennels is 17℃ ~ 2℃ in summer and 13℃ ~ 15℃ in winter. Trees should be planted around the kennel for shade, or shade equipment should be provided for summer heatstroke prevention. In winter, soft grass should be laid on the dog bed or a sleeping box should be set to prevent the cold from attacking.
