What is diarrhea?Diarrhea is when your dog has an abnormal stool (loose stool). This could occur once or frequently. Either way, it is best to pay close attention to this illness.
What are the symptoms of diarrhea?Diarrhea or a loose stool can be accompanied by vomiting, loss of appetite and weight loss.
Why do dogs get diarrhea?As with most animals, dogs tend to put almost anything in their mouth. If your dog is usually healthy and suddenly gets diarrhea, it could be because of a sudden change in diet, scavenging behavior, or a viral/bacterial infection. A more severe (chronic) case of diarrhea could occur because the dog is under stress, has an allergy to something the dog has eaten, or presence of some type of parasites in their body (worms). Other reasons include inflammatory bowel disease or pancreatic disease.
How should you treat diarrhea?For dogs who have diarrhea for the first time (and are otherwise usually healthy):
- Ensure there is plenty of clean water available (to avoid dehydration). And make sure you urge the dog to drink the water (don’t just leave it there).
- Try giving the dog a small meal of boiled rice and boiled egg or boiled chicken (without bones or skin). This should ideally be the diet till the dog is well again.
- If diarrhea persists for more than 1 day or gets worse, call your vet.
- For dogs who have diarrhea and have vomited only once or twice:
- Urge the dog to drink water many times a day
- Avoid food for half a day (or provide diluted chicken broth)
- After about 6 hours, if the dog has not vomited, then give your dog a small meal of boiled rice and chicken (no bones, no skin). Wait for a few hours and repeat this small meal.
- If your dog has frequently passed a loose stool or the stool is water
- If there is more than a streak of blood in the stool
- If there is profuse vomiting or your dog has abdominal pain
How can you prevent diarrhea in your dog?As best as you can, watch what goes into your dog’s mouth, especially when you take your dog out for a walk. Sometimes, dogs chew their pet toys to bits (and swallow the plastic). This should be avoided. Tip: Keep a tab on any change in food that you might give your dog. Any sudden change of diet will induce diarrhea in most dogs so please don’t allow dogs new foods in any large quantities.
Treatment of diarrheaWith hydration, and abstinence of food the stomach should settle. Please always check with your vet. However, if immediate vet care is not available do the following:
- Very severe diarrhea (stool comes out like a jet of water) – inject 1ml of Hyoscine butylbromide per 40kg bodyweight (this available in 1ml ampules in the brands such as Buscogast or Buscopan). Search above on ‘injecting a dog’. This can be given as IM or sub-cut. If an injection is not available, give 10mg tablet per 40kg body weight. The drug will not treat the cause – it will immediately stop the severe stool discharge. Then follow next step(s):
- Severe diarrhea (continuous liquid discharge of stool): Put the dog on Metronidazole IV Infusion. This is typically available as 200ml (500mg) infusion that is sufficient for a 40kg body weight in 2 doses over a day for 5 days. It is available in 100ml infusions as well – use for small dogs. A common brand available is Metris. Metronidazole works well against anaerobic gut bacteria.
- If IV can’t be given or if diarrhea and dehydration is not that severe you can use Metronidazole tablets (commonly available as 400mg or 200mg, brand Metrogyl). If diarrhea persists after 1-2 days some vets will add Norflox-TZ tablets which is a combination drug of Tinidazole (600mg) + Norfloxacin (400mg) + Lactobacillus (120Millionspores). Half a tablet with 1 tablet of Metrogyl will be an appropriate dose.
