Dog diarrhea is a common and usually minor problem. It can be caused by many things, such as changes in food or eating behavior, stomach flu, eating something disagreeable or poisonous, a serious illness or disease, stress and anxiety, excitement and over excitement.

Changes in food or eating behavior

When you take a look at the causes of dog diarrhea, it's important to consider that changes in food or eating behavior can be a factor. This can include:

  • A change in diet, either an increase or decrease in the amount of food consumed.

  • A change in the frequency at which your dog eats. If your pet starts eating more often than usual, this could trigger an episode of diarrhea and vomiting as well.

  • A change in the type of food consumed by your canine companion—this includes everything from treats to table scraps and more serious additions like raw meat or bones (which can cause intestinal blockages).

  • A change in source from which you buy your dog's food from—for example, switching from homemade meals prepared on site at home to packaged mixes sold at stores may lead to unpleasant results if there were ingredients added into them during production that aren't healthy for dogs' digestive systems

Stomach flu

Stomach flu is a general term for vomiting and diarrhea caused by a virus. It can be transmitted between humans and dogs, but not to other animals such as cats. In humans, stomach flu usually lasts 1-2 days and resolves with no treatment. With dogs, however, it's best to seek medical attention if you suspect your dog has stomach flu due to the risk of dehydration and death if left untreated. Your vet will likely want to run some tests on your pooch, including bloodwork (may include checking electrolytes), urinalysis (to check kidney function), fecal floatation (to look for bacteria or parasites) and x-rays (to look at organs). If these tests confirm that your pup has an infection in its stomach or intestines then he might need antibiotics or even hospitalization depending on how severe his symptoms are."

Eating something disagreeable or poisonous

The most common cause of diarrhea in dogs is eating something disagreeable or poisonous. Some foods can be toxic to a dog, but many others do not pose any danger and may even help with digestion.

Below are some foods that are not poisonous, but can cause diarrhea:

  • Candy (or other sweets)

  • Bread dough

  • Pasta and noodles

A serious illness or disease

Diarrhea is the most common symptom of a serious illness or disease in dogs. This makes sense if you think about it from an evolutionary perspective: diarrhea is a way of expelling toxins and waste from the body, which is necessary when there's something wrong with your dog's health. If your dog has been diagnosed with diarrhea, it's important to eliminate any other potential causes before focusing on one particular illness or disease. The list below includes some of the most common conditions that cause symptoms similar to diarrhea in dogs:

  • Parvovirus (canine distemper)

  • Salmonella

  • Giardia lamblia (a microscopic parasite found worldwide)

Stress and anxiety

Stress and anxiety are also common causes of diarrhea. Dogs who are stressed or anxious may have other symptoms, such as vomiting and panting.

Excitement and over excitement

If your dog has diarrhea, it could be because of excitement. Dogs often get diarrhea when they're excited because of a new experience or activity. For example, if you take your dog for a walk in the woods and he sees another dog for the first time in his life, he might have diarrhea from being so excited about this new experience. This usually happens with puppies who are learning how to walk on a leash or older dogs who haven't been walked regularly in awhile. It can also happen if someone brings home something new and exciting (like a new toy or food) for your dog!

In addition to excitement related causes of diarrhea in dogs, there are other causes that don't involve excitement but still cause an increase in intestinal motility which leads to loose stools: eating too much at once; drinking too much water at one time; eating something that disagrees with them like onions or chocolate; exercising more than normal such as running around outside without proper exercise equipment like leashes/collars; not eating enough calories per day relative to energy expenditure which would mean consuming less food than usual (such as during winter when it's cold out all day long).

Lots of things can cause dog diarrhea

You may already know that something as simple as a bad hair day can cause your dog to poop in the house. But it's also possible that something more serious could be wrong with him.

Here are some of the common causes of diarrhea in dogs:

  • Food poisoning

  • Fleas and ticks on his skin that cause an allergic reaction to their saliva (this is called flea dermatitis)

  • An intestinal parasite like Toxoplasma gondii or Giardia lamblia, which live in contaminated water or undercooked meat and can make your dog very sick if he eats them

Conclusion

So, there you have it: the many causes of dog diarrhea. The good news is that most cases can be treated at home, but if you suspect something serious is going on with your pooch, it’s always best to check with your vet first.
