1. Dietary problems of puppies: The breeder may provide the puppies with inappropriate food or insufficient food, resulting in emaciation of the rear abdomen. Please make sure to provide the puppy with a balanced and nutritious diet, including enough protein, vitamins and minerals.
2. Parasitic infection: Abdominal emaciation may also be the result of parasitic infection. The common parasites are ascaris lumbricoides and hookworm, which will affect the digestion and absorption function of puppies. It is recommended to take the puppy to the vet for stool examination to rule out the possibility of parasitic infection.
3. Digestive system problems: puppies may suffer from digestive system diseases, such as gastroenteritis or pancreatic problems. These problems may lead to indigestion and insufficient absorption, which may lead to abdominal emaciation. If the puppy is accompanied by vomiting, diarrhea, loss of appetite and other symptoms, it is recommended to see a veterinarian in time.
4. Other diseases: Some chronic diseases or other abnormal conditions, such as tumors and endocrine problems, may also lead to emaciation of the rear abdomen of the puppy. If the puppy's slimming problem persists with other abnormal symptoms, it is recommended to seek professional advice from the veterinarian.
