Dogs’ Diarrhea: What To Look For?

There are many signs of illness, the main one you should be looking for is the presence of loose stool. This should be enough indicator of diarrhea. Take a sample of it cause your vet will expect one later.

Other signs accompanied with diarrhea could also be:

  • Weight Loss. 
  • Lethargy. 
  • Vomiting. 
  • loss of appetite. 
  • Abdominal Pain
  • Dehydration

You must take a note and write down everything odd you notice on your puppy’s stool (whether its blood presence, mucus, or soft appearance). Your vet will be appreciative as this will later help in the diagnosing process.

Also, you must be patient when diarrhea starts, and you shouldn’t be asking the question, why does my dog have diarrhea just after the first one or two incidents as sometimes it might only result from the bad response of the digestive system towards specific types of foods (like spicy foods, sugar substitutes, or milk).

Diarrhea should become a concern only when it happens in a repetitive pattern, as many different diseases might’ve caused it.

You should be worried about diarrhea when:

  • It lasts for more than one or two days. 
  • When it’s accompanied by fever. 
  • When it’s accompanied by slight dizziness. 
  • More than five loose stools in only 24 hours.

How To Diagnose A Dog With Diarrhea?

The vet will first show interest in knowing your pup’s medical history once the vet has that, the next step should be to perform a set of minor tests designed to tell the vet whether it’s just diarrhea that your dog is having or is it a cause of an underlying disease.

In case that your pup’s diarrhea is severe, you should expect that the vet will do more tests just in case. These diagnostic tests can include the standard X-ray test, blood tests, DNA tests, ultrasound, or endoscopy.

Sometimes your vet might also conduct an abdominal surgery if that was thought to be a must-done.

Treatment Of Dogs’ Diarrhea

If your pup’s diarrhea is mild, you can safely treat it at home by incorporating some new healthy food in the dog’s diet like mashed potatoes, white rice, boiled egg, oatmeal, or chicken.

If your dog was one year of age or older, you might consider withholding food for about 13 hours as it could be the help your dog’s digestive system needs to go back to the normal state.

You should also consider stopping the catch-the-ball game for a little while (or any physical activity like running or walking if that matters) as it could make diarrhea more severe.

However, this sweet home-made treatment shouldn’t eliminate the need for veterinarian help. It could just stop diarrhea, not the diseases associated with it, in case the reason behind it is an underlying illness.
