10 Signs Your Dog Is Sick and When It's an Emergency

Dogs instinctively mask pain, making it hard for owners to detect illness. This guide lists 10 common symptoms—vomiting, diarrhea, appetite loss, lethargy, labored breathing, pale gums, abdominal swelling, straining to urinate, seizures, and excessive drooling—and explains which details indicate a veterinary emergency. Vomiting more than twice, with blood or in puppies, requires immediate care. Diarrhea lasting over 24 hours or with blood needs a vet. Refusing food for more than 24-48 hours, especially in small breeds, is urgent. Lethargy with collapse or pale gums is an emergency. Labored breathing at rest, pale or blue gums, sudden abdominal swelling (bloat risk in deep-chested breeds), inability to urinate, seizures over five minutes, and drooling with distress all warrant same-day or emergency vet visits. The article emphasizes comparing behavior to a dog's baseline and notes that breed, age, and health history affect symptom interpretation.
