◆Sudden changes in food, feeding too much and too many miscellaneous foods. If the method of gradually changing the feed is not followed, the dog cannot adapt to the sudden change of food, which often causes digestive tract diseases.

◆Overfeeding or overfeeding. I'm afraid that the dog won't eat well and won't be full. Eggs, milk, and fire-cooked intestines are all available. You feed it, I feed it, the owner feeds it, and relatives and friends feed it. It's not regular or quantitative. It's weird if it doesn't get sick within three days. .

◆Excessive play with pet toys, adults play with them, children play with them, you give them a hug, I tease them, and the dog doesn’t get any rest.

◆Exhausted from fatigue, reduced resistance, and prone to illness.

◆A dog that cannot adapt to the new environment will feel lonely and helpless when it leaves its original living environment and misses its original owner. If it is not taken care of carefully, the dog will get sick. Especially puppies, which have just been weaned and are not used to being away from their brothers and sisters, will be more likely to get sick if the food and room temperature do not meet the requirements.

◆Improper bathing. Some owners think dogs are dirty and bathe them as soon as they get them home.It is easy to get sick. It is best not to bathe a newly purchased dog.

◆Go out and come into contact with other dogs, and you may be infected with diseases. Even for vaccinated dogs, the protection rate is not 100%, let alone unimmunized dogs. During the period of isolation and observation, newly purchased dogs should not be taken out to play, should not come into contact with other dogs, and should not even be touched by other dog owners to prevent cross-infection.
