Lungworm, slugs and snails
Lungworm (Angiostrongylus vasorum) is a parasite dogs can catch by eating slugs or snails, or by licking their slime from toys, bowls and grass. It is found in many parts of the UK and can be serious if not treated.
How dogs catch it
Dogs do not have to eat a whole slug. Puppies and dogs that eat grass, chew sticks or leave toys and water bowls outside overnight are at higher risk, as slugs and snails crawl over them. Foxes can also carry lungworm, which helps it spread.
Signs to watch for
- Coughing or breathing problems.
- Tiring easily on walks.
- Bleeding that will not stop from small cuts, nosebleeds, or unexplained bruising.
- Weight loss, poor appetite, vomiting or diarrhoea.
- Changes in behaviour, or seizures in severe cases.
Some dogs show few signs until they are quite unwell.
Prevention
- Not all wormers cover lungworm. Ask your vet for a product that does, and use it regularly.
- Bring toys and bowls in at night, and wash outdoor water bowls often.
- Pick up poo promptly in the garden.
Slug pellets
Slug pellets have caused many serious poisonings in dogs. Pellets containing metaldehyde are now banned from outdoor use in Great Britain, but old stocks may still be around in sheds and garages, so check and dispose of them safely. Use pet-friendly methods to manage slugs in the garden.
When to contact your vet
- Coughing, tiring easily, unexplained bruising or bleeding.
- Your dog may have eaten slug pellets. This is an emergency.
- You are unsure whether your dog’s wormer covers lungworm.
