What are the reasons for a dog's diarrhea with blood?

Dog diarrhea with blood is mainly suspected to be caused by infections such as parvovirus, intestinal injuries caused by foreign objects, enteritis, parasite infections, and constipation. The first thing the owner should think about is whether the dog has been vaccinated and dewormed, and whether the smell of the feces is fishy. A fecal examination should be performed on the dog to rule out the possibility of parvovirus and parasites. It is also necessary to review whether the dog has a history of swallowing foreign objects. If not, then the majority of the time, it is caused by enteritis.

1. Parvovirus infection

If a dog has not been vaccinated and has diarrhea with blood, the first thing to consider is whether it is infected with parvovirus. When a dog is infected with parvovirus, it usually shows obvious changes in appetite and spirit, or vomiting, and the feces will have a fishy smell. In this case, it is generally recommended that the owner take the dog to a pet hospital for virus screening and then treat it accordingly.

1. Intestinal injuries caused by foreign objects

If your dog has recently eaten sharp bones or swallowed other foreign objects, it can cause intestinal injuries and bleeding, leading to diarrhea with blood. This usually accompanied by diarrhea. It is recommended to take the dog to a pet hospital for X-ray examination to determine the size and location of the foreign object, and to see if surgical removal is necessary.

1. Enteritis

Improper diet, overeating, eating indigestible foods, or eating spoiled and irritating foods can easily cause enteritis in dogs, manifested as soft stools, diarrhea, blood in stools, vomiting, and other gastrointestinal symptoms. For such diseases as enteritis, it is recommended that the owner first take the dog to a pet hospital for inspection. If diagnosed with enteritis, anti-inflammatory treatment is necessary.

1. Parasite infection

If the owner does not regularly deworm the dog, the dog may become infected with parasites such as coccidia, which can cause mechanical damage to the intestines and lead to diarrhea with blood. In this case, it is necessary to take the dog to a pet hospital for inspection and regular deworming. Generally, the first deworming can be done when a puppy is 1 month old, and then regularly every month. Once the dog becomes an adult, deworming can be done every three months.

1. Constipation

If the dog's stool is very dry and the bowel movement is too forceful, it can cause anal tears, leading to blood in the stool. In this case, it is recommended to let the dog drink more water, eat more liquid foods, and use enemas if necessary.
