If the puppy's temperature is normal, it can be inferred that there is no inflammation or slight inflammation. You can give the puppy something to help him excrete first, such as putting some kaiselu on his ass and feeding him some cooking oil. Then hurry to buy probiotics or enzyme tablets (recommended for dogs and cats, the effect is obvious. I bought Par Boucher and gave them to the puppy. Usage and dosage according to the drug instructions.
If the body temperature rises, it can be inferred that the puppy has inflammation (indigestion turns into gastroenteritis) and bacterial infection (bacteria colonize the gastrointestinal tract and attack the body when the gastrointestinal mucosal barrier is destroyed), and gentamicin can be used and must be diluted (3-5mg/kg, twice a day for two to three days).
If your dog vomits or has diarrhea, you can use metoclopramide (intramuscular injection is better) or motilium 2mg/kg twice a day (orally)//to stop diarrhea-for dogs under 2kg, smecta 1g/ time, 2-5kg- 1.5g/ time, 5-5.
Dogs can fast for about 24 hours at the beginning of the disease, and then explore physiological saline and glucose (not too high concentration). The feeding amount is probably that dogs will not vomit or vomit less times after drinking, which is a supportive treatment for puppies. We must insist on eating.
The above dose is determined. It is recommended to buy needles and pull them out and feed them to dogs quantitatively.
The above measures still don't work after careful implementation. If your conditions permit, send it to the vet as soon as possible.
The above is my experience, I can reprint it at will, without marking the source, hoping to help more dogs.
