Explanation:
Endoparasites
In the UK dogs and cats most commonly suffer from two types of worm, round worms and tape worms.
Currently the most clinically relevant round worms are:
Intestinal (gut) round worm (Ascarids), are transmitted from mother to offspring through the milk. When the larval/immature worms are ingested by the puppies/kittens some develop into adults in the intestines and some go into the tissues where they remain dormant. The dormant larvae will mature into adult worms throughout the dog or cats life. Adult worms produce eggs themselves that will become larvae to infect future generations. Adult dogs and cats with intestinal round worms often do not have any symptoms. Puppies and kittens can become very unwell with round worm infestation, they can suffer diarrhoea, poor weight gain and, in some cases, there can be severe damage to the intestine which can be life-threatening. Young children and immunocompromised individuals can be infected by roundworm larvae.
Lungworm in dogs (Angiostrongylus vasorum) is another form of roundworm which is becoming increasingly common in the UK. The distribution of lungworm is not uniform throughout the country and collection of data is ongoing. A regularly updated map of reported cases has been made available for pet owners by the drug company Bayer who make Advocate spot on (Bayer Map). Dogs become infected with lungworm when they eat a slug, snail or their slime, or frogs that are carrying lungworm larvae. The immature worm travels through the dog’s body to get to the heart where it can mature into an adult. The adult worms produce larvae which the dog coughs up and then swallows, larvae are then pass out in the faeces to infect more slugs and snails and so on. Infected dogs may appear normal, they can develop a cough and exercise intolerance, problems with bleeding and/or larval migration can cause an array of symptoms depending on the area of the body affected, including neurological signs. Lungworm infection can be fatal.
