What are the signs my dog has lungworm?

Dogs of all ages and breeds can become infected with lungworm. However, younger dogs seem to be more prone to picking up the parasite. Dogs known to eat slugs and snails should also be considered high risk.

Lungworm infections can result in a number of different signs which may easily be confused with other illnesses. If your dog is displaying any of the signs below, consult your veterinary surgeon immediately.

Breathing problems

  • Coughing
  • Tiring easily

Poor blood clotting

  • Excessive bleeding from even minor wounds/cuts
  • Nose bleeds
  • Bleeding into the eye
  • Anaemia (paleness around the eyes gums)

General sickness

  • Weight loss
  • Poor appetite
  • Vomiting
  • Diarrhoea

Changes in behaviour

  • Depression
  • Tiring easily
  • Seizures (fits)

There are some dogs which don’t initially show outward signs of lungworm infection. Your veterinary surgeon can perform tests which may help detect if your dog is infected with the lungworm parasite, if you are concerned.
