While most people think that nighttime diarrhea of the dogs is caused due to some unusual bacteria or diseases, the actual reasons are pretty familiar.

The main reason for the nighttime diarrhea of a dog is the sudden change in its diet and trying too many different food menus for it. Parasites, allergies, or reactions to a certain kind of medication could be the other reasons.

The bad news is that dogs suffering from diarrhea at night are the worst victim than usual diarrhea suffered dogs. Hence, these sickened dogs need special care and attention. Thus, you might be keen to know the treatment of such diarrhea cases of your clawed buddy. Also, you should know what to do if diarrhea doesn’t cure even after a few days of home treatment and diet change.

And in today’s write-up, you will get the answer to these questions strictly related to a dog suffering from nighttime stomach upset.

What Causes Diarrhea in Dogs at Night?

There could one or more reasons for a dog having diarrhea at night. The common causes are-

1. Change in the diet:

The main reason is the sudden and frequent change of the dog’s diet. Dog owners often try different kibbles or canned food for their buddies. While continuing a specific kibble or canned food isn’t ideal, a sudden change is too not feasible.

The sudden change of the dry food can be caused due to the rise in price or the item not being available in the market. But, the change of such change in the food menu may upset the dog’s stomach. Also, when you change the puppy’s diet from puppy foods to adult dog food for the 1st time, it may not tolerate the change. Thus, nighttime loose motion can be a common phenomenon in such situations.

2. Parasite attack:

A deeper concern regarding the nighttime diarrhea of dogs is the parasite attacks. The dog’s intestine is full of different parasites, and some of them may come from the outside source to upset the balance. For instance, if a dog drinks water from an unsafe and contaminated source, it is most likely to get caught by the E.coli bacteria, the main culprit of diarrhea and water-borne diseases.

 Also, dirty food or contaminated water will carry hookworm, giardia, coccidian, or the common roundworm. These parasites can upset the intestine too.  If the dog already has a weak immune system, it will most likely fall prey to these parasites. Also, puppies are incredibly vulnerable to such parasite attacks.

3. Due to medication:

A somewhat rare cause of diarrhea of dogs at night could be due to the side effects of medication. When you use any antibiotics or medicated cream to help the dog in different illnesses, it could also be the cause of stomach upsets. For instance, Desitin is used to heal the rashes, scratches, and minor wounds on the dog skin. It contains zinc oxide, which, if ingested, would upset the dog’s tummy.

Also, antibiotics will kill both bad and good bacteria, which will imbalance the intestine of the dog for a short period. It can thus cause temporary diarrhea lasting for few hours only.

4. Allergies:

Just like humans, dogs are prone to allergy and intolerance to a certain food as well. Dogs can be hypersensitive or insensitive to high fat, protein, gluten, or carbohydrates. Such intolerance to food may lead to diarrhea and gas build-up in the dog.

It may vary from one breed to another. Also, some breeds may be sensitive to the sudden ambiance as well. So, consult the vet to know the proper ambiance and food chart of the particular breed.

5. Illness and anxiety:

If the dog is suffering from any diseases, diarrhea at night could be a side-effect too. It can be the signal of an inflammatory bowel system or weak immune too. Furthermore, a sudden change in the living ambiance or a change in ownership puts too much stress on the dogs. It could also lead to sleep disturbance and diarrhea.

What Should I Do If My Dog Has Bloody Diarrhea?

Although diarrhea at night isn’t a red signal for dogs, bloody diarrhea could be. When you see blood coming out with poops or stools, you must take immediate action.

When you see blood in the dog’s stool, observe it properly, even if it seems awkward to you. Check whether the stool is bright bloody colored, or darken.  It will help you better to describe it to the vet instead of calling him to inspect the poop physically.

When you consult the vet, follow his medication and diet chart until the dog comes round. You need to act fast to save the health of the dog during the bloody diarrhea occurrence.
