My Dog Has Diarrhea, What Should I Do?
Diarrhea is a common problem with dogs. They can develop diarrhea for many reasons, but there are some actions you can take at home that can help. Before covering those, first there are a few important symptoms to watch for.
Always bring your pet in for an exam if they are showing any of these symptoms:
- Persistent diarrhea (for more than 48 hours)
- Diarrhea with excessive vomiting (even if not getting much up)
- Liquid, bloody diarrhea
- Major loss or lack of appetite
- Painful, i.e. unable to get comfortable, tense belly, vocalizing
- Marked lethargy
- Frequently re-current diarrhea
(Some significant health problems could cause some of these symptoms; such as: gastrointestinal obstruction, some cancers (especially older animals), pancreatitis, Hemorrhagic Gastroenteritis, IBD.)
If your pet is acting relatively normal and still has a decent appetite, then here are a few steps to take at home:
- Fast for 12 – 24 hours (less time for smaller dogs)
- Provide access to plenty of water, if no vomiting. If vomiting then offer small, frequent amounts
- If occasional vomiting, try famotidine (pepcid AC). Please call and speak with a technician for dosing.
- If diarrhea only, pepto bismol may be used. Again, please call and speak with a technician for dosing.
- Start a bland diet after period of fasting. (75% cooked white rice/25% boiled, skinless, boneless chicken or cooked lean hamburger) Offer in 2 small meals per day for 2 – 3 days.
- Transition slowly back to regular food by gradually increasing amount of regular food and decreasing bland diet per meal over a period of 2 – 3 days.
If your pet is not improving within 24 hours, please call or schedule an exam.
Some common causes of diarrhea:
- Stress
- Switching foods too fast
- Parasites
- Eating things they shouldn’t, i.e. trash, human food, plants, mulch or rocks.
- Treats that are new to them
