About Puppy Diarrhea

Diarrhea in puppies is SO common that your new pup is likely going to have at least one episode of loose stools during his first few weeks with you.

Diarrhea can be caused by....

  • changes in diet 
  • stress 
  • worms
  • illness/disease
  • eating stuff he shouldn't

Although your little guy might get 'the squirts' from something as simple as a sudden change in puppy food or getting into the trash can, it's can also be the first sign of several serious illnesses.

Diarrhea in puppies should never be ignored - or even taken lightlyespecially if there's vomiting as well.

If you're in any doubt, or worried, always get veterinary help/advice right away - it's better to be safe than sorry.

Most Common Causes Of Diarrhea In Puppies

Here's a closer look at what could be causing your puppy's pooping 'problems'...

  • Eating stuff he shouldn't
    Puppies seem to operate on the assumption that everything is edible until proven otherwise... this leads to all sorts of things entering their digestive system that should never be there!
  • Worms or other intestinal parasites
    Most young puppies have worms. Either they're born with them, or they pick them up during the early weeks.
  • Infections and illnesses
    Until they've had all their puppy shots, these little guys are very vulnerable to several contagious dog illnesses. They're also prone to parasites that can cause loose stools or diarrhea, and there are other things such as allergies, colitis or food-absorption issues that can also be to blame.
  • Stress
    Leaving their doggie family, traveling to a new home and adjusting to a new home/family are all stressful for a puppy and weaken his immune system. That can allow parasites such as Coccidia to flourish and cause trouble.
  • A Change In Diet
    Most puppies start on a new, and different, puppy food when they get to their 'forever homes'. A sudden change in diet can upset your pup's tummy pretty easily.

Of course it's natural to worry when your puppy's poop doesn't seem normal, but although an occasional episode of mild puppy diarrhea isn't unusual, it can be cause for concern.

The information below explains more about the different types of puppy diarrhea that you're most likely to see, what each type could mean and what you should do.

Mild - Moderate Puppy Diarrhea

Diarrhea in puppies can range from a soft 'pile' to a jet of water... and just about everything in between!

If your pup has a couple of soft, chocolate-pudding-type stools, don't panic right away.

This sort of diarrhea usually doesn't last for more than 24 hours and can be caused by a simple tummy upset.

Your little guy might perfectly normally, or he might seem a little quiet or look sorry for himself, but he shouldn't look really ill, be inactive, or refuse a drink or a treat (even if he doesn't want his dinner).

A Change In Diet
When you pick up your new puppy home, it's a good idea to ask what type of puppy food he's been eating up to this point.

Then make sure you stick with that for the first week or so because suddenly switching your puppy from one brand of food (or from dried to canned, commercial to home-made etc) is one of the most common causes of puppy diarrhea.

If you decide you want to change the brand of food your new pup is eating that's fine, but make the transition slowly.

A puppy's digestive system can be fairly delicate and is easily affected by stressful situations. Things such as leaving their mom and siblings, a visit to the veterinarian, getting used to a new home environment, excess excitement or exercise and so on, can trigger a bout of loose stools.

Stress can also allow a parasitic infection called Coccidiosis to take hold. These parasites exist in most pups/dogs, but are kept in check by the immune system.

When a young puppy is stressed, his immune function is repressed and coccidia can flourish. If your puppy's diarrhea gets worse quickly, is watery or is tinged with blood/mucus then coccidia or a viral/bacterial disease might be the problem.

Eating Something He Shouldn't
Little puppies are endlessly curious, and often seem to believe that EVERYTHING is edible, until proven otherwise!

If your pup has been snacking on left-overs from the garbage can, the flowers or dirt in your front yard, the cat's food, newspaper, crayons, or some other 'inedible' stuff, then he's most likely going to have at the very least some loose stools, possibly some diarrhea and/or even vomiting.

A surprising number of every-day foods and other items are toxic, or dangerous for your puppy to ingest. You can find a list of the ones most likely to cause trouble on my Poisonous Foods page.

If your pup has a mildly upset tummy and this type of diarrhea, a good probiotic can help 'reset' his system. I'd recommend Nutramax Proviable Kit for Cats and Small Dogs.

It not only rebalances his digestive system by encouraging the growth of 'good bacteria' in Fido's gut, but also helps to firm-up his stools.

Dog food allergies
 and sensitivities are more common than many owners realize, and these can cause diarrhea in puppies, and dogs. True allergies are more likely to cause skin irritation or inflammation and itching, whereas a 'sensitivity' to an ingredient may cause loose stools or even vomiting.

High-protein puppy foods are also more likely to cause loose, unformed stools in some puppies.

Other Dog Health Conditions
Dog diseases or conditions which can cause chronic diarrhea in puppies and/or dogs.

These include pancreas problems, inflammatory bowel conditions (including Colitis), liver disease, gall bladder problems, adrenal issues, tumors and more.

Some breeds seem to be predisposed to conditions which cause chronic loose stools.

These include Shetland Sheepdog, Collie, German Shepherd, Irish Setter, Boxer, King Charles Spaniel, Golden Retriever, Miniature long-haired Dachshund, French Bulldog, Yorkshire Terrier, Soft-coated Wheaten Terrier.

Moderate - Severe Puppy Diarrhea

If your puppy has repeated, watery diarrhea that contains blood and/or mucus, or looks black,  it's likely to be an emergency situation and you need to get him to a vet right away!

If the diarrhea is liquid (anything from soupy to watery) then it is time to worry. 

I'm not saying that you need to panic, but you definitely need to get your little one to your veterinarian as soon as you can.

These stools are are usually caused by one of two things.....

Parasitic Infection
Your puppy could have developed an infection caused by parasites, such as Coccidiosis or Giardia, both of which can cause pretty severe, foul smelling diarrhea (sometimes accompanied by vomiting, lethargy and loss of appetite).

A bad case of puppy worms (particularly roundworms, whipworms or hookworms) can also result in your pup suffering from diarrhea and/or vomiting.

You might also notice that his stools contain a lot of mucus because the worms cause a lot of internal irritation. This is most often seen in very young puppies who haven't been dewormed yet, or older pups who have never been treated for worms, or not treated often enough.

Disease Or Illnesses - Many Of Them Serious
Many of the most contagious, serious (and often potentially deadly) dog illnesses have diarrhea as one of the earliest symptoms.

This kind of diarrhea is usually very watery, and can contain mucous and/or blood (shows as red or brown). It's usually frequent, and may spray or 'jet' out with some force.

Dog diseases such as Distemper, Canine Parvovirus, Hepatitis and Corona Virus are just some of the possible reasons for this type of puppy diarrhea and all of them need emergency treatment.

As I mentioned above (and can't stress enough!), watery diarrhea that's has streaks of blood or contains mucus is a red flag.

Don't 'wait-and-see', get veterinary help IMMEDIATELY. Your puppy's life could literally depend on it.

Internal Bleeding
Black or 'tarry' looking stools could be a sign of internal bleeding.

The blood could be coming from Fido's stomach or his small intestine.

Trauma to the belly is the most common cause of internal injuries and bleeding, but diseases such as Diabetes or cancer can also cause blood loss like this.

Severe cases of diseases such as Parvo can cause bleeding in the gut which often appears as red, but may also be much darker, even black.

As long as the loose stools your little one is experiencing don't fit the 'consult a veterinarian now!' criteria above....

..... and you've figured out what is causing the problem, then there are things you can do to help his digestive system get back to normal.

The link below will get you both on the right track.
