Is My Dog’s Diarrhea an Emergency?
Diarrhea in dogs is common — and in many cases, it’s mild and self-limiting. But sometimes diarrhea can signal something more serious.
As emergency veterinarians, one of the 2nd most common questions we hear is:
“Do I need to take my dog to the ER for diarrhea?”
Here’s how to tell.
When Diarrhea IS an Emergency
Seek emergency care immediately if your dog:
Has large amounts of bloody diarrhea
Is vomiting along with diarrhea
Is lethargic or weak
Has pale gums
Is unable to keep water down
Shows signs of abdominal pain
Is a puppy, senior pet, or very small breed
May have ingested something toxic
Has underlying medical conditions (diabetes, kidney disease, etc.)
Severe diarrhea can quickly lead to dehydration and electrolyte imbalances — especially in small dogs and puppies.
When You May Be Able to Monitor at Home
You may be able to monitor closely if your dog:
Has soft stool but is still bright and alert
Is eating and drinking normally
Is not vomiting
Has no abdominal pain
Has had a recent diet change
Mild diarrhea can sometimes occur from dietary indiscretion, stress, or minor GI upset.
However, if symptoms persist beyond 24 hours or worsen, veterinary evaluation is recommended.
Special Situations
Puppies and and small dogs can become dehydrated very quickly.
Large volumes of bloody diarrhea (especially with lethargy) may indicate infectious conditions, which requires prompt treatment.
If you’re unsure whether your pet’s diarrhea is mild or something more serious, it’s better to get guidance sooner rather than later.
