Cases are on the rise across the UK, and it is thought this is down to warmer, wetter summers, which are ideal conditions for slugs and snails to breed. This is combined with greater movement of people and their dogs, helping to spread the disease around.
Younger dogs under the age of two tend to be more at risk, as are dogs who spend a lot of time outside – that have more chance to swallow lungworm larvae.
It is worth knowing more about lungworm, how dogs contract it, the symptoms to look out for and what lungworm treatment is available. If you suspect your dog has lungworm, you’ll need to seek veterinary treatment straight away.
How can my dog get lungworm?
Luckily, most dogs do not actively look to eat slugs and snails as they omit a foul-tasting slime. On the downside, lungworm can be picked up if your dog accidentally licks or eats grass that a slug or snail has crawled across or drinks from water outside. They can also contract lungworm if a gastropod crawls over any toys or chews left out in the garden.
By ingesting slug and snail slime, your dog is swallowing the tiny larvae excreted by their hosts. The larvae burrow through your dog’s gut wall and travel back to the heart and around the body as they turn into adults.
What are the symptoms of lungworm?
Lungworm symptoms differ from dog to dog and can vary, depending on how heavy the infestation is and which organs the worms are inhabiting. The most common symptoms are:
- Heavy, laboured breathing, particularly during exercise
- Coughing and bringing up blood
- Weight loss and loss of appetite
- Vomiting and diarrhoea
- Seizures and unexplained collapsing
What lungworm treatment is available?
Lungworm treatment varies, depending on the severity of the illness and the symptoms. If the symptoms are mild, your vet may prescribe lungworm treatment and medication to take home. If your dog is very ill, they will need intensive treatment at a veterinary hospital.
How do I stop my dog from catching lungworm?
It is far better to prevent your dog from catching lungworm in the first place. Here are some good habits you can put in place:
- Using a good worming regime, which includes lungworm protection, is essential. Ask your vet which prescription wormer is best for your dog. It is worth noting, off-the-shelf brands of wormer from pet shops and supermarkets are not veterinary licenced. This means the ingredients are less effective
- Dog-friendly slug pellets can help keep the number of slugs and snails in your garden at bay, but this has been shown to be an ineffective way to prevent lungworm
- Remove dog faeces from your garden regularly to help break the cycle of larvae transferring from the environment to your dog
- Bring dog toys and water bowls inside at night, lessening the chance of them being contaminated by gastropod slime
If you need any further advice on lungworm treatment or prevention, contact your local vet.
