Depending on the dog's condition, a normal dog will defecate once or twice a day, but this may also vary depending on the dog's age, health, diet, living environment and other factors. Young, active dogs may need to poop more frequently, while older or less healthy dogs may need to poop less often. So if your dog usually poops once a day but suddenly doesn't poop for two days, this could be a sign that needs attention.

So, it is not necessarily normal for a dog to not poop for two days, but it does not necessarily mean that the dog Have serious health problems. If your dog develops other symptoms or continues to not defecate, it is recommended to contact your veterinarian for diagnosis and treatment. At the same time, regular physical examinations and providing a healthy diet and living environment for dogs can also help prevent defecation problems in dogs.
