How to detect illness in dogs? Practical methods for identifying when a dog is sick
When dogs suffer from different diseases, they will show corresponding abnormal manifestations (symptoms) in one or certain aspects. Using the following methods of examination, sick dogs can be detected. It is necessary for dog owners to master some of the most commonly used basic knowledge in this regard, so that sick dogs can be discovered in time and some simple treatment can be carried out. Never think that the diagnosis and treatment of dog diseases is only a matter for veterinarians and that "it is none of your business and you stay aloof." (1) Look. The content of looking has two major aspects: first, under quiet conditions, look at the dog's mental state, behavioral manifestations, and reactions to external stimuli; second, look at the dog's body surface condition (coat, skin, natural orifices, etc.) and the characteristics of its excrement, etc. (2) Listen. Directly listen to whether the dog's barking and breathing sounds are normal, and whether there is panting, coughing, or sneezing, etc. A stethoscope or short tube can also be used to listen to the heartbeat, breathing, and gastrointestinal peristaltic sounds. (3) Measure. Commonly use a veterinary thermometer to measure the temperature in the rectum (37.5-38.5°C for adult dogs, 38.2-39.3°C for puppies). A dog's body temperature changes regularly within a day, lowest in the early morning and slightly higher in the afternoon, and the difference between day and night generally does not exceed 1°C; if the temperature difference is too large or there is reversed fever (high in the morning, low in the evening), then it is abnormal. You can also hold the dog's ear with your hand to sense its body temperature. (4) Touch. Use the palm or back of the hand to touch a certain part of the body surface to determine the temperature and sensitivity of the skin there, muscle tension, and whether the adjacent internal organs are normal (position, size, texture, and whether there is pain). The heartbeat or pulse condition is also very easy to feel clearly with the hand. (5) Percuss. Tap the corresponding areas on the body surface (projection areas) of organs such as the dog's stomach or intestines with the fingers to judge whether they are normal.

Ten observation points for sick pigs, so pig farmers can quickly identify swine diseases
At present, for rural farmers raising pigs, in terms of feeding and management, some people pour feed into the pig trough and turn around and leave, rarely paying attention to observing the pigs' growth and development or whether they show signs of illness. As a result, they do not know when a pig gets sick, and by the time the pig is down in the pen, it is too late and difficult to treat. To prevent disease before it occurs and treat it early when it does, symptoms must be discovered in time. Observation can be made from the following ten aspects. 1. Look at demeanor.

How to Identify and Control the Tea Green Leafhopper
The small green leafhopper, also known as the floating dust hopper, is the most important pest of tea plants. It damages tea plants by having its nymphs and adults pierce and suck the sap of young shoots, buds and leaves, causing the buds and leaves to yellow and lose their green color, the leaf veins to turn red, and the leaf texture to become coarse and old. In severe cases, the leaf tips and margins become reddish-brown and scorched, the buds and leaves shrivel, growth stops, and they may even be completely scorched, as if burned by fire.
