There have been 187 cases of lungworm recorded within a 50 mile area of Bolton and dog owners have been urged to take precautions.

Data released by Bayer shows that cases have occurred in Hindley, Atherton and Radcliffe, as well as in the surrounding area.

Warm, wet weather encourages slugs and snails, increasing the chances of dogs contracting lungworm.

PDSA Vet Nurse Nina Downing said: "Lungworm is becoming more common in dogs across the UK. They can catch the deadly parasite if they eat infected slugs, snails and frogs; they might do this accidentally when they eat grass, drink from outdoor water bowls and puddles or play with toys which have been left outside.

"Lungworm infections are very serious and can be fatal. However, the good news is you can easily prevent infections by following a regular worming programme, with a product that includes lungworm prevention.

"Symptoms of lungworm include coughing and breathing problems, weigh loss, seizures, blindness and bruising caused by blood clotting problems. It's very important to contact your vet immediately if your dog is showing any of these symptoms."
