Newborn Puppy Bleeding From Anus – Should You Be Worried?

Puppies’ stool is usually soft within the first five weeks and becomes harder, like that of adult dogs.

However, if you are facing the issue of a newborn puppy bleeding from anus, there’s something wrong with your small friend.

As dog lovers, we all feel worried and confused in this situation.

That’s why I wrote this article to explain the possible causes, how to diagnose, and what remedy to give to your dog. Scroll down right now!

Cause of Newborn Puppy Bleeding From Anus

The reasons for rectal bleeding in dogs include worms, viruses, food intolerances, constipation, infection, etc.

You can guess the cause by looking at the color of the stool. For better diagnosis and treatment, reach out to your vet.


Why is my 1-month-old puppy pooping blood? The worms are the number one reason your dog has painful and bloody stools.

Worms (such as small hookworms) may be invisible, or you can see them in the stools together with the blood.

You can ask your vet for a stool inspection. If he finds the worms inside, over-the-counter medication will be given.

Usually, after the medication works, the stools should return to normal. Regularly deworming can help clean your dog’s stomach.


Is bright red blood from the anus serious? Bloody abnormal stools always indicate serious situations, especially if it’s caused by viruses.

One of the most common viruses is parvovirus.

Parvo is dangerous and can kill your puppy. There is no home remedy or home cure for this type of virus.

I highly recommend you bring your pet to the clinic to check for parvovirus before conducting any home method.

Strange Food

It’s possible that your dog swallowed unfamiliar food or inedible things, leading to the situation of a newborn puppy bleeding from the anus.

The strange objects can be a piece of wood, plastic, or any other materials, and even the airpod, resulting in damage to the digestive tract.

The popular home remedy is to wait until your dog passes the object out and stops bleeding.

However, it might cause injury during waiting time, or the thing may not even come out. So, you’d better ask a vet for an examination.

Hemorrhage In The Digestive System

Why is my dog bleeding bright red blood from his anus? Hemorrhage in any part of the digestive system can lead to dog rectal bleeding.

Thus, diagnosis is important to understand where the blood is expelled.

The fecal exams are done by examining the stools’ texture and presentation.

Professionals will check if feces is mixed with blood, what’s on the outside of the wastes, and what color of the blood to conclude the bleeding cause.


Can overfeeding cause blood in poo in puppies? An imbalanced diet or eating too much can lead to constipation.

In turn, it can cause dehydration in dogs, making the stools dry up and difficult to be expelled. Thus, you may see blood in your dog’s anus.

Constipation can also result from side effects of medications or diseases such as hypothyroidism.

If your pet has abdominal pain or can not defecate at all, call a vet as soon as possible.

Infection Of The Anal Glands

A dog has two glands on two sides of the anus. When the feces pass through and apply pressure on these glands, they will empty the liquid to lubricate.

However, if your pet has a gland infection, the place will be dry, causing canine rectal bleeding.

You can observe common symptoms. Your dog frequently licks the area or rubs his bum on the ground to see if there’s an infection.

Usually, draining the glands and giving antibiotics will cure your pet.

Other Causes

Why is my 5-week-old puppy pooping blood? Bleeding can also occur when your pet has inflammatory bowel disease and cancer.

Since the reasons are various, I highly recommend you visit a veterinarian for proper diagnosis and treatment options.

How To Diagnose The Reason?

What if my 7-week-old puppy has blood in his stool? To find out the reasons, you can conduct the two methods below:

Observe The Dog’s Overall Health

If your pet has bloody poop but acts normally without lethargy, you can ask your vet for advice.

Describe the situation, and the vet will assess whether your pet needs a clinical examination.

Together with anal bleeding, if your canine does not feel well and has abnormal symptoms such as vomiting or lack of appetite, you should call the vet immediately for emergency care.

It’s not good to let the situation linger on.

Diagnose The Dog’s Stool

What’s wrong when a dog bleeds from the anus? Depending on the color of the stool, the causes can be inspected.

  • Bright Red Color

The issue of bright red color bleeding is called hematochezia. If there’s a small amount of blood, your pet is likely fine. The more blood, the more serious it can be.

For weak puppies with lethargy, vomiting, and weight loss possibly have hemorrhagic gastroenteritis (HGE) or contracted canine parvovirus, potentially leading to fatal if left untreated. Other causes also include:

The consistency and presence of blood in the stool can help you identify where the blood comes from.

Your canine’s poo is normal in texture and coated with a red-blood outer layer, which means somewhere in the low area of the intestinal tract has troubles.

Meanwhile, diarrhea and soft feces mixed with red blood indicate problems in the higher place.

Dark, Blackish Red, & Tarry Color

In this case, the blood has been staying in the gastrointestinal tract for a long time or has been digested, and your pet may have issues around the stomach.

It’s called melena and can be hard to spot.

The reasons for this blood color include:

  • Addison’s disease
  • Foreign objects
  • Inflammatory bowel disease (IBD)
  • Bacterial infections
  • Kidney failure
  • Liver disease
  • Pancreatitis
  • Parasites
  • Reaction to a medication
  • Tumors
  • Toxins
  • Ulcers

What Home Remedy Is Good For A Dog With Bloody Diarrhea?

The common home remedy is:

  • Keep 12-hour or 24-hour fasting (no food is allowed, but give access to water).
  • Then, feed your pet with cooked squash, pumpkin, or sweet potato with lean meat broth for 24 hours.
  • Give canine-specific probiotics to your pet.
  • After 24 hours, feed your canine again.
  • Keep giving non-dairy probiotic
  • The activated charcoal tablets can be used if you suspect your dog consumes spoiled food.

The Bottom Lines

The issue of a newborn puppy bleeding from anus is serious or not depending on what causes the problem and where the bleeding comes from.

You can apply the home remedy above for your pet, yet there’s nothing wrong with seeking help immediately from your vet to ensure your dog for physical examination and can recover well.
