How to Tell If Your Dog Has Coccidia

1 Symptoms

Signs include blood at the end of the stool, dullness, jelly-like mucus in the faeces, and dehydration. Some infected dogs show no symptoms at all; puppies are both more likely to catch it and to show it more sharply.

In puppies the disease moves fast: mild fever, poor digestion, diarrhea, lost appetite, and heavy mucus in the stool. Severe cases show bloody, brownish stool, then weight loss, anaemia, dehydration, and even collapse and death. With 2–3 weeks of treatment some puppies recover. Adult dogs resist better and often show few or no signs, mending slowly with care.

2 How Dogs Catch It

Dogs that roam often, live in poor hygiene, or mix with other dogs catch coccidia more easily, picking up eggs from contaminated objects or infected faeces. In a large kennel the disease can spread widely and, left unchecked, do real damage — so isolate any dog that tests positive and step up deworming and prevention.

3 Diagnosis and Treatment

If you suspect coccidia, take the dog for a fecal microscope exam to confirm eggs are present. Once diagnosed, treat with a sulfadimethoxine-based dewormer, and watch for severe diarrhea — to avoid dehydration, give IV fluids to restore balance.

Preventively, clean and disinfect the living area often and keep food fresh. A dog that licks everything outdoors can wear a muzzle to avoid swallowing egg-laden water or food, and a yearly health check helps catch problems early.
