Snail and rat baits

In autumn and winter, snails and rodents become a pest and as a consequence we see an increase in the number of dogs poisoned by snail and rat baits.

The two most common poisons in snail baits are methiocarb (blue coloured) and metaldehyde (green coloured).

Depending on how much is eaten, the signs of snail bait poisoning may occur within minutes to hours after ingestion.

Both methiocarb and metaldehyde cause varying degrees of salivation, muscle tremors, vomiting and diarrhoea. Death is usually from respiratory failure. Rat baits work differently to snail baits. They usually contain warfarin or related compounds and these work by preventing blood from clotting.

Unlike snail baits, it takes 2-5 days after ingestion before the signs of rat bait poisoning appear.

The signs vary depending on the site of bleeding, but generally include anemia (pale gums), weakness, shortness of breath and you may notice bleeding from the nose, blood in the urine or blood in the faeces.

The key to successful treatment is recognising the signs early and calling your vet.

Make sure that all baits are kept in cupboards out of reach of children and pets.

Put snail pellets in containers in the garden that dogs cannot access and make sure rats can’t drag baits out into the open where your dog will find them.

As a general rule, ALL snail and rat baits should be regarded as harmful to your pets regardless of the manufacturers’ assurances.
