The four normal needs. The four major needs of puppy growth are appetite, play, sleep, and excretion. Puppies have changed environments, bumps in the road or food changes may reduce their appetite, but severe dehydration, gastroenteritis, or body pain can also make them lose their appetite. In this case, wait and see and observe for a few days.

No runny nose. Dogs have a runny nose when they catch a cold, have an upper respiratory infection, or are naturally allergic to the nose. If infected with bacteria, the snot will become opaque, creamy white, yellow or green and sticky. Also, if food is ejected from the nostrils, there is a problem with the dog's swallowing mechanism.

Don't cough. Dogs with cold, cloudy air, sensitive throats, or bronchitis or bronchitis can all cause puppies to cough. Severe coughing and phlegm can make puppies have a poor appetite.

A moderate build. Body fat and thin is an important indicator of the healthy nutritional status of puppies. Body weight loss can lead to lack of physical strength, weakened immunity, and affected health. Note that judging fat and thin is the body other than the coat. In addition, it can also be measured by the thickness of the muscles on the back of the abdomen.

The eyes are bright. The cornea of a healthy eye should be transparent and the color of the pigment layer of the eye can be seen clearly. Cornea turning blue may be infected with hepatitis virus. Red or white cornea may be the result of foreign body entry or trauma. Infection with dog distemper or other eye pathogens can cause the eye to secrete abnormal substances or purulent.

Observe hygiene. The sanitation of the puppy's body can reflect the care of the previous owner. If the puppy's body is dirty, its chance of contracting diseases will be greatly increased. Because most of the bacteria and parasites of infectious diseases are transmitted through urine and feces.

No pain. If the puppy is often bent on one side and moaning and does not eat, it is necessary to check whether it is stomach pain, which is a common symptom of gastroenteritis. If the dog is reluctant to walk, or is in pain when walking, it is necessary to suspect whether there is trauma to the limbs and bones.

Stools are normal. Changes in the environment and diet of puppies or enteritis and parasites will cause abnormal stools, such as soft and transparent substances, which should be noted. A normal stool should be in the form of slime strips.

Watch the blood. To determine whether the puppy is anemic or malnourished, open its lips and observe whether the color of the gums and flesh is bright red. If there is a problem with hematopoiesis or if there are parasites, the blood will appear pale.

Healthy skin. Observe the dog's skin for health. Pus or dander can make the dog feel itchy, and scratching the skin can affect its appearance and health. should be treated with caution.
