Signs of worms in puppies

If your puppy has worms, you might see them squirming in their stool or notice a bloated belly, dull coat, weight loss, or scooting. Different worms cause slightly different symptoms, so here is what to look for.

Visible Signs of Worms in Stool

Roundworms look like spaghetti. Tapeworms look like cucumber seeds or grains of rice (they may be stuck to your puppy’s rear end). Hookworms are too small to see easily, but your puppy may have dark, tarry stool. Whipworms are also tiny. If you see any worms, collect a fresh sample and take it to your veterinarian.

Physical and Behavioral Signs

Bloated belly – a potbellied appearance, especially in puppies.
Poor coat – dry, rough, or dull fur.
Weight loss or poor growth – eating normally but not gaining weight.
Scooting – dragging bottom on the floor due to irritation.
Coughing – can be a sign of roundworms migrating through the lungs.
Diarrhea or vomiting – sometimes with visible worms.
Lethargy – less playful or tired.
Increased appetite – may eat more than usual.

How Worms Affect Puppies

Worms steal nutrients, irritate the gut, and can cause serious health issues. Roundworms can cause pneumonia if they migrate to the lungs. Hookworms feed on blood, leading to anemia (pale gums, weakness). Tapeworms rarely cause severe illness but can block the intestine if enough are present. Whipworms cause chronic diarrhea.

What to Do If You Suspect Worms

Take your puppy to the veterinarian for a fecal exam. Do not treat without a diagnosis – different worms require different medications. Your vet will prescribe a dewormer; some are given as a single dose, others over several days. Puppies should be dewormed regularly starting at 2 weeks of age, even if no worms are seen.

Preventing Worms

Keep your yard clean of feces.
Prevent your puppy from eating rodents or feces.
Use monthly heartworm prevention that also controls intestinal worms (your vet can recommend one).
Wash your hands after handling your puppy.

Remember, some worms (like roundworms) can be transmitted to humans, especially children. Practice good hygiene and consult your veterinarian for routine testing.

If your puppy has any of these signs, see your veterinarian promptly. Early treatment is simple and effective.

Key Takeaway

Watch for visible worms, bloating, poor coat, scooting, or diarrhea, and take your puppy to the vet for a fecal test rather than treating blindly.
