Lungworm - the hidden canine killer

Watch out for the slimewave: Washout summer brings unexpected peril for dogs as number of slugs carrying killer disease trebles


The slug ‘slimewave’ sweeping Britain because of the wet weather has triggered an explosion in a killer dog disease, experts warned yesterday.
Rising numbers of pets are contracting lungworm through eating infected slugs, who have doubled, or even trebled, in number.
The disease can cause lethargy, breathing difficulties, occasional vomiting, coughing, nosebleeds and can be fatal.

Dog charity PDSA has already seen a dramatic increase in the number of dogs who have contracted the disease this year and is now warning pet owners to ensure their dogs are protected.
Sean Wensley, a Senior Veterinary Surgeon at PDSA, said: 'The killer disease is on the rise because of the wet, humid conditions, which has seen an epidemic of slugs and snails.
'With reports of an increase in slugs and snails due to the recent wet weather, it is important for dog owners to be aware of the risks of lungworm, which dogs can catch if they eat an infected slug or snail.

 'If you are concerned that something may be wrong it is important to contact your vet, as without treatment, lungworm can be fatal.
'A regular worming programme is also vital, so speak to your vet to ensure that your dog is receiving the necessary protection.
'Your vet will understand the lungworm risk in your area and can offer advice accordingly.
'Some dogs will purposefully eat slugs and snails, whereas others may accidentally eat them when playing with toys outside, eating grass or drinking from puddles.
'If you are trying to control slugs and snails, remember that slug pellets can be poisonous to cats and dogs, so if you must use them, do so with great care.
'Alternative methods include encouraging hedgehogs into your garden, which will feed on up to 100 bugs, including slugs and snails, every night.'

The combination of a mild, frost-free winter and the recent cool, damp spell has allowed the population of slugs to soar, leading to the rise of the disease.
Lungworm can be contracted by dogs when they eat infected slugs, snails or faeces from other infected dogs or foxes, or when they’re bitten by a mosquito.
If not caught in time it can cause long-term heart problems, and on many occasions lead to death. It can, however, be prevented using specific flea treatments.
One recent victim was Amber, a one-year-old crossbreed who was diagnosed at the PDSA in Cardiff earlier this month.
She started bleeding from her nose just two weeks after being adopted by Lorna Black, 49, a clerical and accounts worker from Rhoose, Glamorgan.
'I’ve had dogs for 17 years and I didn’t know about lungworm,' said Lorna. 'Now, I don’t even leave her toys outside in case a slug gets on them.

The monster mollusc discovered by Don Proctor in Torquay is about twice the size of most garden slugs.

Slugs found in gardens are typically between two and three-and-a-half inches long, although measurements vary depending on the species.

There are 30 species of slug in the British Isles.

The longest is the limax cinereoniger, which can grow to almost 12 inches - making it the world's largest.

It is found in woodland and parks across large parts of Europe.

Earlier this month it emerged that the unsettled weather had caused Spanish slugs to invade our gardens.

The pest grows to more than four inches long and produces hundreds more eggs than the typical British slug.
'She’s now eating but I still feel she had to have rests, although she’s definitely perked up. All the family’s dogs have now been given preventative treatment.'
Britain’s gardeners and farmers have also faced an slug epidemic which have wreaked havoc cost millions of pounds of damage to commercial crops.
Researchers have found up to 1,000 slugs per square metre in some areas - meaning the total population in Britain could be a staggering 15billion.
Slug expert Dr Richard Meredith, of Bayer Crop Science, one of the world’s leading crop science companies, has been monitoring slug populations for years.
He believes slug populations have doubled or even tripled this year as certain breeds can lay up to 500 eggs at a time in the right conditions.
Dr Meredith said: 'At this moment in time, the conditions over the last couple of months have been really good for the slugs to reproduce.
'As long as it’s wet and warm, they just keep going.
'They like the rain and warm, and we prayed for rain, and now we’ve had months of it - and the slugs are thriving.
'If it carries on the way it is, we can expect to have a serious challenge with protecting crops.
'It’s a real threat to British agriculture as well - growers that have fields that have a history of slug damage will have to be on their best vigil to prevent their crop being lost.'
But super-sized slugs - such as one measuring more than six inches from tip to tail that appeared in a Torquay garden - prove that there are some creatures who are more then happy with the extreme wet weather.
The monster mollusc turned up in Don Proctor's garden in Torquay, Devon, having thrived on the wet weather and munching on Mrs Proctor's precious plants.
Floods and heavy rain have helped create ideal breeding conditions for the slimy molluscs, which are crawling over flower beds and destroying produce across the country.
'My wife's a keen gardener and she's noticed her plants have been slowly disappearing - now we know why,' Mr Proctor said.
'I've never seen one quite so big as this one. I think they're usually between a quarter-inch to four inches long. This one was six inches. It was a whopper.'

June was one of the wettest on record in the UK, with torrential rainfall causing floods in many areas around the country, and the April - June quarter was the wettest second quarter in the UK since records began in 1910.
The Met Office believes that repeated Atlantic weather systems have inflicted wind, rain and lower than average temperatures on at least one part of the UK daily since June 19.
Seaside resorts have already suffered 113mm of rain this month - almost three times as much as they would normally see during the whole of July.

The Met Office has issued a yellow warning of rain across the south and south west of England, saying flooding is likely due to the already rain-sodden ground.
A spokesman for the National Farmers Union said the slug infestation had been disastrous.
'On a good night a slug can munch its way through 50 wheat seeds after they’ve been planted,' he said.
'They can travel over five metres a night, they can smell food over 60 centimetres away and then they’re all over it. They’re not good news.'
Birds such as thrushes and blackbirds might disagree, however.
In a normal spring when the sun comes out and the ground dries, they have trouble finding enough worms to feed their young.
But the rapid increase in the snail and slug populations has led experts to predict a better breeding season, with many more chicks surviving to adulthood.
