Questions Owners Ask
Should I go to the emergency vet?
Go the same day, and now if the dog is a puppy, is vomiting, or is flat and dehydrated. Bloody diarrhea in a puppy is a parvovirus question until proven otherwise. A single streak of fresh blood on a formed stool in a bright adult can be seen promptly and still should not wait a week.
How much will treatment cost?
Blood in the stool should be seen the same day, especially if it is dark and tarry or the dog is also vomiting and flat. The exam looks for parasites, colitis, a foreign body, and parvovirus in a puppy. A fecal test and fluids are the costs to ask about on arrival.
Can I treat this at home?
Save a photo of the stool and withhold food for a meal only if the clinic tells you to and the dog is bright. A puppy with bloody diarrhea needs the clinic now because parvovirus kills quickly. Do not give a human anti-diarrheal.
