A simple guide to worming your pet

What deworming covers, how often to do it, and signs you shouldn't ignore.

Intestinal worms — roundworms, hookworms, tapeworms, and whipworms — are common in pets of every age. Many pets carry them without obvious signs, which is why routine deworming matters.

Puppies and kittens should be dewormed every 2 weeks from 2 to 8 weeks of age, then monthly until 6 months. Adult pets typically need treatment every 3 months, or more often if they hunt, eat raw food, or live with young children.

Heartworm is a separate, mosquito-borne parasite and needs its own monthly preventive — usually a chewable prescribed after a quick blood test. Skipping months can be dangerous; treatment for an active infection is far harder than prevention.

Watch for: visible worms or rice-like segments near the tail, scooting, a pot-bellied appearance in puppies, weight loss despite a good appetite, or persistent diarrhea. Bring a fresh stool sample to your next visit if you're unsure.
