The signs seems settling so I would not be extremely concerned at this stage. As a first approach, I would suggest to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice vomiting, lethargy or inappetence.

    Hello Maria, I'm so sorry to hear that Dele is not feeling well. If a dog is eating and drinking normally, we will often recommend a bland easily digested diet consisting of ½ cooked white rice and ½ cooked white meat chicken (boiled without any skin or bones). However, diarrhea that continues for more than a few days, or is associated with blood in the stool, vomiting, lethargy or a poor appetite is a reason for a visit to your veterinarian. Very dark brown black stool can be due to bleeding in the stomach, so that is always potentially concerning. I would recommend having your veterinarian examine Dele, so they can give him some medication for the diarrhea and try to figure out what has caused the problem. I have attached a couple of links below with more information for you that might be helpful.

I hope that was helpful and that he feels better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
