Why does my puppy have diarrhea overnight? 

Your puppy may have diarrhea at night because of changes in their diet, food intolerance & diseases, feeding on spoilt food, allergies, medication, or parasitic infestation. If you notice they are not getting well even after the home intervention, take them to the vet for treatment.

Before rushing your puppy to the dog, find out if you’ve introduced new things in his life, from food and toys. If you have also brought home a new pet, it may be the reason your puppy is experiencing significant stress or anxiety over sharing space and your attention. Try to address all these factors; if none work, you can take your puppy to the vet.

Always be careful with your dog’s food and the environment they play in, as they can easily collect dirt and feed on bad food. 

Also, ensure that you are taking your puppy for regular vet checks, and whenever you bring a new pet home, ensure you get them acquainted before leaving them in the house together

Reasons Why Your Puppy has Diarrhea at Night

These are some of the reasons why your puppy might be having diarrhea.

Medication

If your puppy is sick, chances are you’ve been prescribed medication for their treatment. These medicines might be the reason your dog has diarrhea at night. Some medications that cause diarrhea include dewormers, observed even in humans. This will take a few days until your dog’s body is rid of all worms.

Every time the vet prescribes medicine for your puppy, discuss their side effects so you know what to expect.

Stress or Anxiety

Our puppies are susceptible to changes in their environment, so their bodies respond by having diarrhea when they experience a stressful moment or have anxieties. So when you bring a puppy home from the breeders, be sure that for the next few days, your puppy might experience diarrhea as they adjust to their new home.

Or, when you bring home a new pet, they might face the stress of having to share their space and your attention. Therefore, they might appear to be clingy and sometimes to the point of wanting to sleep with you. 

So, take time and introduce your new pet to your puppy; sometimes, you can spoil them by sleeping with you on the bed.

Pinpointing the source of their stress and anxiety will help you help them improve their digestive system.

Spoilt Food

While out playing or taking a walk, your dog might have picked up food from the garbage, which is contaminated, thus the reason why they have an upset stomach.

Change of Food

It is common for dogs to experience food allergies before their owner can know exactly what to feed them. So do not panic if you have recently introduced new food or treats to their diet. When exploring food, ensure that you don’t provide them multiple products, only single products, as it will help you identify what foods they are allergic to.

Although dogs feed on human foods, some don’t go well with their digestive system. So, when introducing a new diet, ensure it’s done in the morning and not at night to avoid or minimize nighttime diarrhea.

Ailments

Your puppy may be having diarrhea at night because they are ill. Some diseases that can cause diarrhea include cancer, Inflammatory Bowel Syndrome, Colitis, and liver or kidney disease.

Parasites

Night-time diarrhea in your puppy might also be caused by parasitic infestation in the intestines. Your pup’s drinking water may be infested by parasites, such as hookworms, giardia, roundworms, or Coccidia. These parasites weaken your puppy’s body, causing explosive dog diarrhea.

Your dog may have eaten raw meat or contaminated food. And this can expose them to various bacteria and viruses, including salmonella, parvoviruses, or clostridia, which cause nighttime diarrhea.

Inflammatory Bowel Disease

This is a condition where your puppy’s gastrointestinal tract becomes inflamed due to underlying health conditions or bacteria and parasitic infection. 

When the digestive tract is inflamed, it inhibits your puppy’s digestion and absorption of nutrients, taking a toll on their body. This leads to your dog having diarrhea at night, and the poop has blood or mucus.

The minute you see mucus or blood in your puppy’s stool, consult your vet immediately.

Ways to Ensure Your Dog Doesn’t Experience Diarrhea at Night

We all want our puppies to be healthy and comfortable. So, it would be best if you did everything possible to prevent them from experiencing diarrhea, irrespective of the time of the day. You can do so by following these tips.

  • Note your dog’s bathroom pattern, especially if they poop outside. This is because you won’t have a chance to look at their poop closely. If you notice that they want to be let out more often, they might have colitis.
  • Always consults your vet before feeding your dog any medication. And when buying over-the-counter medication, always read the packaging to understand the side effects.
  • After noticing that they have diarrhea, withhold food for 12 hours. This will give them time to clear off everything in their intestines and allow their stomach to rest.
  • Then introduce them to a simple diet after the rest. Start with a soft, bland diet, such as plain rice and cooked chicken. Feed your puppy in small portions and frequently. And once you notice that their poop is back to normal, you can return to your regular feeding schedule. And remember to add treats to their meals.
  • Ensure your dog is on a monthly heartworm or tick preventative schedule. This helps prevent parasite infestation and protects them from getting heartworm disease. These medications also contain dewormers to protect your puppy from intestinal worms.
  • Always ensure your puppy is happy and doesn’t experience any stressful situations.
  • Feed your dogs food that will help soothe their upset stomach. These include natural yogurt, white rice probiotics, cottage cheese, or peeled boiled potatoes. You can also feed them herbs such as fennel or specially formulated dog food for the digestive system.
