Senior Dog With Oily, Soft Stool and Drops of Water After Antibiotics

Antibiotics commonly upset the gut and cause soft or loose stools, which usually settle within a few days to a couple of weeks after the course ends. A few drops of clear fluid or mucus at the end of a soft bowel movement, along with going in several spots, suggests the colon is irritated. An oily look can be extra mucus, or a sign that fat isn't being digested properly.

The "screw-type" worm you saw is important. Please take a fresh stool sample, or the worm itself in a sealed bag, to your vet so it can be identified. Heartworm preventives given less often than directed won't reliably protect her against heartworm or intestinal worms. Ask your vet about a product and schedule that suit her, about a heartworm test, and mention that the preventive seems to make her sick. Call your vet sooner if she has blood in her stool, vomits or stops eating.
