Worms in Dogs
Worms in dogs are parasites often causing diarrhea, vomiting, and weight loss. Prevent them by maintaining regular worming schedules and good hygiene.

What are worms?
Worms are parasites (organisms that live inside your dog.)
Where does my dog get worms from?
- Most commonly, dogs get worms by coming into contact with feces from an infected dog.
- Puppies can pick up Worms from their mum while still in the womb and through her milk if she is infected. WORMING PUPPIES IS VERY IMPORTANT!
- There are a few different types of worms that your dog can catch; most of them live in the stomach and intestinal tract.
- The two most common intestinal worms are roundworms and tapeworms.
What are the signs of worms?
- Some dogs can have worms but only appear unwell when heavily infected.
- Some of the signs that could suggest your pet has worms include:
- Diarrhea (from very severe to just a little bit loose)
- Vomiting
- Weight loss, especially if they also seem very hungry
- Some dogs (especially puppies) can have a round or swollen-looking tummy
Diagnosis of worms
- Sometimes worms can be seen in a dog’s poo. They can look like spaghetti or bits of rice.
- Despite being infected you may not always see worms in your dogs poo.
- Worm eggs are too small to be seen by the naked eye but can be tested for in a laboratory (poo sample).
Differentials (problems that look like worms, but aren’t)
- Bacterial Infections (e.g. Salomnella, E.Coli and Campylobacter): These are of particular concern as they can be also passed onto people.
- Cancer: This is much rarer for us to see, but given how serious it is, it’s important to rule out.
- Foreign Objects: Sometimes, symptoms that look like worms can be caused by foreign objects like a toy or string. If dogs eat these items, they can then get stuck, causing vomiting and diarrhoea and then further, more dangerous complications.
- Vomiting, Diarrhoea, and Weight Loss: These are very common signs of lots of different diseases, which is why it is important that your pet is seen and given a though examination and investigations as necessary.
Treatment of worms
- In most cases, treating worms is very simple.
- Dogs can be dewormed with either a tablet or a paste that can be given at home.
The prognosis for worms (how a dog is likely to do afterward)
- Most dogs recover very well, with no long-term problems.
- Very young puppies with very high numbers of worms can do very poorly and may need extra support and aftercare, but thankfully it is less common to be severe.
