In the UK, worms in dogs are a common issue. They can lead to ill health and distress in our pets and can re-infest them at any time. Across the entire world there are many types of parasites which are grouped under the term ‘worms in dogs’ but in the UK we deal primarily with just two. They are the roundworm and the tapeworm.

Roundworms are problematic because they are passed from one animal to another and many puppies are even born carrying them. This type of worm resembles short lengths of spaghetti. Mature worms live in the dog’s intestines and feed on the contents. This means that the partially digested food is eaten by the worms, forcing your dog to share its dinner. Depending on the severity of the infestation, dozens of worms could be present at any one time. Of course, it is logical that under nourishment will be a consequence of a dog having to share its food. Where infestations are particularly severe, the dog will have a dull coat and appear to be lacking in energy. The dog may also suffer with diarrhoea and vomiting. Puppies with roundworms typically have a swollen abdomen and delayed growth. Puppies which are not treated for their roundworm infestations can actually die from intestinal blockage. It is also important to bear in mind that sometimes there will be no symptoms of worms in dogs. Regularly treating dogs for worms is therefore very important.

Worm larvae typically migrate around the body of the adult dog, settling and forming cysts in the muscles. In this form, even worming treatment cannot remove the larvae. The larvae remain inactive in the body of the adult dog and are only reactivated in a time of stress. They will normally reactivate when the dog is pregnant and migrate to the womb to infest the puppies. This is why it is important to worm all puppies.

Worms in dogs can actually cause problems for people as well. Because they are more likely to come into contact with soil or sand that has been contaminated with worm eggs whilst playing, children are especially at risk. Worm larvae can migrate through the child’s body and have been known to cause lasting eye damage if settling near the back of the eye. Regular treatment for worms in dogs is therefore vital to protect the health of the entire family.
