What a healthy stool looks like is worth learning by heart, because it is often the first place a change shows. Expect brown colour, a firm log shape that holds together when picked up, a surface that is slightly moist rather than shiny or greasy, and an easy passage without straining or accidents, typically one to three times a day depending on diet and size. Small variations with diet changes, excitement, or a new treat are normal; what matters is your dog's usual pattern and whether a change persists. Colour carries information: black and tarry suggests digested blood, red streaks suggest fresh blood, orange or yellow can point to liver or bile issues, and pale grey greasy stools can signal pancreas problems.
Reading Changes Like an Owner, Not a Search Engine
Judge a stool by the company it keeps: a single soft stool in a bright, eating, drinking dog is a watch-and-see; diarrhoea with vomiting, lethargy, blood, straining with nothing produced, or a puppy or senior going downhill is a vet conversation the same day. Note what else changed — new food, scavenged rubbish, stress, medication — because that history is diagnostic gold. Worms visible in stool (rice-like segments or spaghetti strands), mucus coating repeatedly, or a dog losing weight on normal food all earn a routine-but-prompt appointment. Keep a dated note of episodes: 'loose every morning for a week' is a different problem from 'one bad day', and your notes are how a vet tells them apart.
Working With Your Vet
With stools, your job is to record colour, consistency, frequency and straining accurately, then let the veterinarian interpret what that pattern means. A phone photo of an abnormal stool, the date it appeared, and a note of any new food, treats, medication or scavenging in the previous two days give the examination a running start. General reading can tell you which combinations merit a same-day call; it cannot identify parasites, infection or organ disease from appearance alone, and it should never delay an appointment for a dog who is also vomiting, lethargic or passing blood.
Blood in stool, black tarry stool, diarrhoea lasting beyond 48 hours (24 in puppies), or diarrhoea with vomiting or lethargy needs a vet — same day for puppies and unwell dogs.
Keep the stool record specific to digestion rather than logging everything at once: consistency, colour, mucus or blood, how often he strained, and what he ate in the day before each change. A fortnight of entries like that can separate a food sensitivity from an infection pattern far more clearly than a recollection offered in the consulting room. Look back over the entries whenever his diet, medication or household routine changes, because his normal baseline may shift and the older notes are what prove it has.
Those dated observations travel as a portable packet in the Pet Passport inside KinsLe, so each consultation builds on the last set of stool notes rather than starting again.
