It will help a veterinarian to accurately diagnose the cause of blood in a dog's stools if they have a sample to test. It's important that the sample is recent and moist, passed within the last six hours. Place the sample inside a new sealable bag or a stool pot provided by the vet and seal it securely.
However, if the dog appears very unwell or is refusing food and water, it's important to get it to the vet as soon as possible instead of waiting for it to pass a stool to obtain a sample.
