Types of worms in puppies

There are four major types of intestinal worms in puppies to be aware of:

  • Roundworms are long, white worms and resemble spaghetti, residing in the small intestine. 
  • Hookworms are shorter than roundworms and have sharp, biting mouthparts. They attach to the intestinal wall and feed on blood. In severe infestations the blood loss can be fatal.  
  • Whipworms can cause significant disease in dogs of all ages. These parasites reside in the large intestine, where their thin heads burrow into the intestinal wall.
  • Tapeworms do not generally cause significant signs of illness in dogs. The flea tapeworm, the most common tapeworm infesting dogs in Australia, is transmitted by fleas. 

Worms in puppies symptoms

Symptoms of worms in puppies can vary depending on the type of worm. Signs may include:

  • Diarrhoea: Bloody diarrhoea may develop with hookworm infestations, while dogs with whipworms may experience diarrhoea with mucus. There are many causes of diarrhoea in puppies so it’s best to consult your vet.
  • Pot belly: A common symptom of roundworm in puppies.
  • Itchy bottom: Rubbing their bottom on the ground is a potential indicator of worms in puppies. However, an itchy bottom can also result from other conditions, so it’s important to consult your vet.
  • Worms in puppy faeces: Sometimes worms (or segments of worms in the case of tapeworms) may be seen in puppy faeces. This can actually be one of the side effects of deworming a puppy as the dead or dying worms may be passed in the faeces. 
  • No symptoms: Frequently, there are no symptoms at all. For instance, puppies and dogs with tapeworms typically do not display symptoms.

How to choose a dewormer for puppies

When looking for the best dewormer for puppies, the sheer number of options can be confusing. It’s important to always check the product information for the minimum age and weight of the product to be used. Talk to your vet if you need advice so you can choose the right product for your puppy.

Side effects of deworming a puppy

Puppy deworming products are generally very safe and effective, however, all medicines for humans and animals have the potential to cause side effects. If you have any questions about the safety of a product for your individual puppy, it’s best to speak to your vet.
