If your dog’s bleeding symptoms are caused by bacterial infection, you can take gentamicin. However, before using any medication, the safest approach is to take your dog to the vet. Your veterinarian will perform a complete physical examination of your dog, including blood work and fecal examination, to determine the exact cause of the diarrhea.

If the veterinarian diagnoses a bacterial infection and thinks gentamicin is appropriate The owner should follow the veterinarian's instructions to give the dog treatment. However, if diarrhea is caused by something else, such as parasites or anal gland problems, then other treatments may be needed. Therefore, do not use gentamicin blindly.
