The short answer is yes, it can. Dogs communicate signs of illness through their behaviour and their stool. A stool with a moist, firm texture and chocolate brown colour is a healthy sign. Healthy stools have a round, log-like appearance. Dog poop should not contain fur, grass, objects or pests.
Hard, round pellet shapes may indicate dehydration. Ensure your dog has 24/7 access to drinking water. Watery stool or mucus-covered stool means your dog has some tummy troubles. When in doubt, consult a vet when your dog's stool displays signs of ill-health.
Keeping your dog's gut health in check is easy with a well-balanced diet and adequate hydration. Feed your dog a vet-approved dog food in a wet or dry formula and feed it on a set schedule. Puppies need twice as much nutrition as adults and lots of drinking water. Avoid giving your dog human foods or treats; their digestive systems differ from that of humans.
