As your dog’s “daily lab report,” poop offers fast clues about health. Here’s what to look for! Quick, practical, and vet-approved.
1) Size
Healthy stool is generally log-shaped and proportional to your dog’s size and diet. If you notice persistent changes such as very small pebbles (possible dehydration/constipation) or extra-large volumes (malabsorption/diet issues) you should speak with your vet. If diarrhea persists beyond 24–48 hours, especially with lethargy or blood, seek care promptly.
2) Color
“Normal” spans shades of brown (from bile pigment metabolism). Concerning shades:
Red or streaked → possible fresh blood from lower GI irritation; call your veterinarian.
Black/tarry → digested blood (melena) and can be an emergency.
Yellow/mucousy → possible intestinal irritation or Giardia.
3) Consistency
Aim for formed, log-shaped, and pliable: not so hard you can’t dent it, not so soft it leaves a residue. Prolonged looseness risks dehydration; very hard stools can signal inadequate hydration or fiber (or anal gland discomfort).
4) Foreign Material
Strings, grass, plastic, fabric, pebbles, or wood chips can indicate dietary indiscretion or pica. Foreign bodies with vomiting/bloating are urgent.
5) Parasite Watch
Seeing worms, rice-like segments, or mucus calls for a fecal test. CDC guidance highlights that roundworm (Toxocara) eggs from dog/cat feces can infect people - one more reason to pick up every time and wash hands.
