My Puppy Has a Worm

Animals that slurp, sniff, and guzzle anything on their way, including trash, are bound to pick up pests and parasites.

Dogs are the best hosts for parasites as they do everything with their mouths; they wrestle, groom, lick, and even greet other dogs with their mouths. This can pass worms to other dogs and humans too.

Several worms live in the intestines that may infect your dog; these include tapeworms, roundworms, whipworms, heartworms, and even hookworms. There are different symptoms to show that your dog is suffering from worms.

Dogs show different signs depending on where the worm infestation and what type of infection it is.

Four different types of worms and how to identify them


Roundworms are the most common worms in dogs, and puppies are the most susceptible to this type of infection. They may get it from their mother’s milk or from eating small creatures like rats. Most dogs do not show symptoms of roundworms unless it is a severe infection. Below are some of the signs

  • Potbelly
  • Weight loss
  • Gloomy fur
  • Coughing is a symptom that the roundworms have moved and are infecting your puppy’s lungs
  • Light brown or white color on your puppy’s face
  • Diarrhea
  • Vomiting


Hookworms live on the digestive system of the puppy, and they are intestinal parasites. They attach themselves onto the inner lignin of the abdominal wall and feeds on the puppy’s blood.

The worms lay eggs that are passed out through your puppy’s poop into the environment. Below are some symptoms that your puppy is suffering from hookworms;

  • Weight loss
  • Bloody diarrhea
  • Weakness
  • Itchy paws
  • Stunted growth
  • Pale gums


Whipworms mostly attach themselves to the colon, and they cause irritation of some kind to your puppy’s tummy.

They cause deterioration in the quality of health, especially to young puppies and dogs with compromised immune systems. Most dogs don’t show signs of whipworms in the early stages, either.

However, in severe infections, the puppy might show severe symptoms such as:

  • Weight loss
  • Bloody stool
  • Diarrhea
  • Anemia
  • Gastrointestinal bleeding


Puppies can undoubtedly get heartworms from mosquito bites. The worms travel to the lungs and the heart through the bloodstream.

Heartworms are expensive and difficult to treat, and they are fatal to dogs no matter their ages.

Heartworms larvae take up to 6 months to grow into adulthood; this means that your puppy will not show any infection symptoms in the early stages. However, after six months from the day of infection, your puppy may start to show the below signs;

  • Persistent soft dry cough
  • Inflated belly die to excessive fluids
  • Weight loss and anorexia
  • Loss of appetite
  • Fatigue
  • Difficulty in breathing
  • Rapid breathing
  • Nosebleeds
  • Excessive sleeping


Dogs can easily get tapeworms from swallowing fleas infected with tapeworms larvae.

Tapeworm, however, is the easiest worm to identify and treat in dogs. It has a plat segmented bodies that resemble the length of tape, and each segment looks like a grain of rice.

Tapeworm can grow up to 28 inches long. It may cause your puppy to experience very uncomfortable symptoms, but it is not as lethal as heartworm. Tapeworms attack the walls of the dog’s gut, and it feeds and continues to grow. Below are some symptoms that your dog is infected with tapeworm

  • Vomiting
  • Diarrhea
  • Dull coat
  • Lethargy
  • Weight loss
  • Visual evidence of tapeworm
  • Skin irritation
