Signs Your Dog Has Worms & What to Do

Common Signs Your Dog Has Worms

You may notice small white squiggly worms in your dog’s stool, or segments that look like grains of rice near the anus. These are key signs of intestinal parasites. Other symptoms include vomiting, diarrhea, and unexplained weight loss. Puppies may also have a bloated or distended belly, especially if infected with roundworms.

Types of Worms and How They Spread

The most common worms in dogs are roundworms (Toxocara canis), tapeworms (Dipylidium canis), and coccidia. Roundworms are one to three inches long, white, and often seen in stool. They’re common in puppies and spread through eggs in feces or contaminated soil. Tapeworms appear as flat, white segments resembling rice and are usually picked up by eating fleas or infected animals like mice. Coccidia are microscopic and cause diarrhea, especially in stressed puppies or dogs in unsanitary conditions.

Why You Shouldn’t Self-Treat

Worming your dog regularly or when it looks sick is not recommended. This can mask serious symptoms and waste money. Home treatment without a vet’s guidance is risky. A proper diagnosis requires a stool sample checked by your veterinarian. Only treat based on confirmed results.

How to Prevent Worms in Dogs

Prevention starts with regular vet check-ups and stool testing. Control fleas, as they carry tapeworms. Avoid letting your dog eat rodents or other animals. Keep your yard clean and remove feces promptly to reduce contamination. Puppies should be wormed on a vet-recommended schedule, but not on a guess.

When to See a Vet

If you see worms in your dog’s stool, notice rice-like segments, or observe vomiting, diarrhea, or weight loss, contact your vet. A stool sample is needed to identify the parasite and choose the right treatment. Never give worming medication without a vet’s advice.
