Is my dog's straining & red anus normal after vet exam for diarrhea?

Updated On September 23rd, 2025

Pet's info: Dog | Chinese Crested | Male | neutered | 12 years and 5 months old | 16.2 lbs

I took my Chinese Crested dog to the vet today about diarrhea, and the vet did a rectal exam on him and prescribed bland food. 3 hours later, I'm noticing my dog straining to defecate (nothing is coming out) and he has a brownish-red anus. I'm wondering if that's normal after the exam, or should I be taking him to an emergency clinic (his vet is closed now)? I don't want to stress him any more, but I'm worried that this is a new symptom since we saw the vet earlier.

The brownish red anus is likely due to the underlying gastritis/inflammation of the gut and the repeated defecation due to the diarrhea. The straining to defecate is probably because Tango is empty from having so much diarrhea. (Poor guy!). You should follow the bland diet directions provided by your veterinarian. There is no need to go to the ER vet now. However, if the diarrhea does not resolve within the next 24 hours despite the bland diet, you will need to take Tango back to your veterinarian or to the ER vet if your regular vet is unavailable.
