2. Oral examination mainly focuses on secretions, teeth, gums and breathing. Healthy dogs don't have any strange secretions in their mouths except saliva. If there is foamy secretion, it means there is a health problem. Healthy dogs should have white teeth. If there is tartar or tooth damage, it can be considered that there is something wrong with the dog's health, but it is not serious. Gums. Dogs should have pink gums. If its gums are gray, it means that the dog has a health problem. It may be internal bleeding, weakness and malnutrition, congenital anemia or other diseases. Breath is not a matter of principle like teeth, but most dogs with bad breath prove that their diet is unhealthy.
3. The dog's nose is wet in a healthy state (the dog's nose is dry after waking up, and the healthy dog is also dry). The color of healthy dogs with runny noses is transparent and clear. If it is yellow and sticky with cough, it means that the dog has some kind of respiratory disease, which may be a cold, dog cough, pneumonia, or it may be the prophase of canine distemper. When choosing a dog, you can pinch some food and shake it in front of its nose. If it chases your hand with your shaking, it means its sense of smell is fine.
The dog's eyes should be clear and clean. Congestion of the eyes, white film on the eyeball, a lot of gum in the corner of the eye and prominent meat in the corner of the eye are all unhealthy symptoms. When choosing, you can put it in a higher place, shake it in front of its eyes with your hands and observe its reaction. If it shows fear and doesn't dare to jump down, its eyes shake with its hands, indicating that its vision is normal.
5, check the dog's skin is mainly to prevent him from having skin diseases and body surface parasites. Gently separate the dog's hair by hand. If the skin is light pink, it means that the skin is healthy. Focus on the skin around the dog's mouth, under the neck, behind the ears, under the armpits and at the root of the thighs, because these places are prone to mites. If the skin is red, massive or flaky, it means that the skin has been infected with mites or fungi. I suggest you not to choose, because this disease is very troublesome to treat and easy to recur. If a large number of small black particles are found in the hair and the skin color is abnormal, there may be fleas. Many dogs have dandruff, which is a sign of lack of vitamins and long-term lack of sunshine; Or the bath liquid used for bathing is wrong, so don't be particularly nervous. A variety of skin diseases will give off a pungent smell, and a healthy "puppy" smell is also an important indicator to judge skin diseases.
6. Dog excrement is also a standard of dog health. If the dog has loose bowels and the stool is thin, it means that there is something wrong with its digestive system or the intestinal flora is destroyed. The worst case is infected with canine parvovirus. If you can't see its excrement, you can lift your tail to see if there is stool around the anus. Generally, only the hair around the anus of dogs with diarrhea will stick to the stool.
7. The normal pace of this kind of dog is stable and energetic. If the dog's pace is abnormal, it may be because it is too small and its muscles and bones are immature. After three months, if there is something wrong with the dog's pace, it means that the bone is injured or has been injured. There are also some dogs with brain injuries that can also cause behavioral sequelae. 38~39 degrees is the normal range. The pads of adult dogs are plump and firm; The dog's foot pads are soft and delicate. If the mat is dry and cracked, it means malnutrition. If the dog baby's foot pad is hard, it may be an early manifestation of canine distemper.
