If the dog eats too much cold food or ice-cold food, causing vomiting and diarrhea, it is recommended to feed an appropriate amount of probiotics to regulate the gastrointestinal environment. If your dog is infected with internal parasites such as roundworms, tapeworms, and leptospira, it is recommended to undergo internal deworming immediately. If your dog also appears depressed, lethargic, or has an elevated body temperature, it may be caused by a viral infection. It is recommended to consult a doctor for medication.

If you only have vomiting and diarrhea, you may have a bad stomach or gastrointestinal indigestion. But if the diarrhea is still bloody, it is likely that you have a parvovirus infection.

Canine parvovirus disease clinically manifests into two types: myocarditis type and enteritis type. Myocarditis type mostly occurs in puppies aged 4-6 weeks. The main symptoms are physical weakness, pale mucous membranes, and difficulty breathing, which are obviously different from canine distemper. Enteritis type mostly occurs in puppies under 5 months old.
