Ask for help, the puppy is about 40 days old, it seems to be a little wilted, and it hasn t eaten fo

Dogs can not eat ham and milk.

It's cold, buy a lot of Qingda, be careful not to catch a cold.

Observe whether the dog's mouth and feces are normal, if there are symptoms such as bad breath, salivation or difficulty swallowing, it may be caused by oral diseases. If your dog has symptoms of diarrhea, it may be caused by a gastrointestinal disorder. Internal parasites, internal organ diseases, etc. can also cause the dog to wilt and not eat, you can take the dog to the hospital for examination**.

If your dog has symptoms of diarrhea, it may be caused by a gastrointestinal disorder. Internal parasites, internal organ diseases, etc. will also cause the dog to wilt and not eat, you can take the dog to the hospital for examination**.

There may also be physiological factors, such as unsatisfactory food, hot weather, excessive exercise, extreme fatigue, the dog is in a full state, thirst or days, including the third trimester, etc., will cause the dog to have no appetite and desire to eat. Generally speaking, improving dietary conditions, increasing the flavor of food, feeding probiotics to regulate the lower stomach and intestines, and inducing dog feeding are common methods used by most dog owners, but this method is only effective for anorexia caused by physiological factors.

If it is a pathological factor that causes the dog to wilt and not eat, such as uterine pyometra, kidney disease, pancreatitis, and even canine plague, etc., it will cause the dog to be in bad spirits and not eat. It is recommended to take the dog to the hospital for biochemistry testing, and if there is a disease, it must be timely**.

There is such a possibility, so first of all, it is necessary to observe whether it has other symptoms, such as fever and wilting, bloody poop, etc., this situation is more serious. Take it to the hospital to check if it is small, dog plague, etc.

Second, if the factor of disease is excluded, another reason is that dogs are picky eaters.

Third, the dog ate something that was not easy to digest the day before, or the dog ate too much (the dog generally does not know that it is hungry): the dog eats things that stay in the stomach for a long time, such as a large number of bones, these things will make the dog's stomach a great burden, and it is easy to cause bad appetite in the next few days. In such cases, the amount of food given to the dog should be reduced.

Fourth, dogs have a bad stomach, many dogs are born because of the wrong feeding method, such as the above point, give the dog too much food, eat things that should not be eaten, and over time lead to gastrointestinal problems.

Fifth, parasite problems: Dogs suffer from parasites generally with ascariasis, and the other is Fasciola hepatica. Both of these diseases can cause anorexia in dogs at one stage, but Fasciola hepatica tends to quickly become hyperphagia and develop ascites.

Ascariasis, on the other hand, in addition to anorexia, can also cause chronic emaciation. In this case, the dog should be dewormed.

Sixth, dogs lack trace elements. When the dog lacks trace elements in the body, it will not like to eat and be anorexic. At this time, the dog should be supplemented with a variety of trace elements.

It's hard to say, maybe it's too hot and I don't want to eat. If you feel uneasy, you should take it to a regular pet hospital to have a look.
