How to treat my dog that has black diarrhea and no energy? Pet's info: Dog | Chihuahua (Smooth Coat) | Female | 5 years and 1 month old | 10 lbs

I would take Allie into the vet immediately This black diarrhea means there is bleeding in the upper intestinal tract, and this can be caused by eating something toxic, trauma to the GI tract, a foreign body, GI ulcers, or GI tumors among other causes. Bloody diarrhea can be very serious, especially if the dog has no energy, and this is not something that should be attempted to be treated at home. Allie needs veterinary care to determine what is causing this bleeding so she can be treated correctly. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. I hope this helps!

If he is behaving normally otherwise and has pink gums, then you can try withholding food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts until the stool is normal then transition slowly to the regular diet. If symptoms persist or if, at any time, he develops lethargy, pale gums, vomiting, diarrhea, loss of appetite or abdominal pain then he should be seen by your veterinarian or at the nearest veterinary ER. You always have the option of having him seen sooner. At best, he will get a clean bill of health and you will have peace of mind if everything checks out. Given current events, you may need to drop him off at the clinic then wait for your vet to call you to discuss exam findings and treatment options.
