Lungworm can cause fatal bleeding in dogs

Number 5 in our wander through the wonderful world of parasites is the LUNGWORM.

Lungworm is an increasingly common parasite in dogs (there is one that affects cats but it is quite rare). It is transmitted via slugs and snails (and their slime). Some dogs will eat large slugs and snails, but many can inadvertently eat them when eating grass, or picking up balls or dog bowls contaminated with slime.

Even very small slugs and snails can transmit lungworm
Dogs that eat grass are at particular risk

Signs of lungworm infection can include:

  • coughing
  • lethargy
  • seizures
  • persistent bleeding or bruising
  • weight loss
