Losing a dog to poisoning is devastating, especially when it is wholly avoidable, says David Tomlinson
Dogs and slug pellets don’t mix and are in fact a lethal combination.
However, it’s the time of year now when new shoots are coming up in the garden and you want to protect your hostas, bulbs and tender green shoots from voracious slugs. So if you’re a dog owner and keen gardener you need to read the advice given here carefully. It’s also worth knowing how to make a dog vomit in an emergency, when your best friend has gobbled down something he shouldn’t and you need to get it out of his digestive system fast. (You might also like to read how to stop a dog chewing on the wrong things.)
Losing a fit and healthy dog through poisoning is dreadful, as illustrated by this story I heard.
Be careful and keep a watch on walks
During a walk on farmland in Kent a lagotto Romagnolo bitch discovered a small pile of bright blue pellets at the side of the road- accidentally spilled – and promptly ate them.
The owner saw her dog eat the pellets, realised at once what had happened and rushed the animal straight to the vet. Despite the fact that the vet knew the type of pellet and followed the correct procedure for such treatment, the dog died 48 hours later.
Of course the owner was devastated to lose a dog in such a way.
Dogs and slug pellets – lethal
- Official figures report that about 10 dogs a year are known to be killed by slug pellets
- However the real figure is probably much higher, as vets may well treat a dog displaying symptoms of metaldehyde poisoning — metaldehyde is the highly toxic poison used in most slug baits — but have no proof that this was the cause of the dog’s sickness.
- In these cases, the cause of death is usually described as possible or probable.
- About three per cent of a slug pellet is made up of metaldehyde.
- The number of pellets a dog has to eat for the effect to be fatal varies, but as a general rule it is about 100 milligrams for every kilogram of the dog’s weight.
- For a spaniel that would be about a tablespoon of pellets.
- There has long been concern about dogs and other mammals eating slug pellets, so the manufacturers are required to add denatonium benzoate, commonly known as Bitrex, a bitter-tasting substance, in a bid to make the pellets unpalatable to dogs and wildlife. However, dogs will often bolt food down before they have tasted it.
The law on slug pellets
- All commercial users of slug pellets must have received adequate training and guidance in correct use.
- Importance is given to avoiding any spills, such as placing a plastic sheet under the spreader when filling in the field.
- Any spilt pellets must be cleaned up immediately, as the real danger to both dogs and wildlife is when there is a pile of pellets.
Farmers are also asked to erect warning signs if pellets have been spread near a public footpath, but that is not much help to those of us working gundogs. Nor is the advice I found from one National Farmers’ Union spokesman, who suggested that dogs should always be kept on leads while on farmland.
Protecting dogs from poisoning by slug pellets
- Be very aware that your dog may encounter slug pellets when you are working or exercising them.
- You are more likely to find slug pellets in crops like cereals, oilseed rape, potatoes, vegetables and sugar beet where slugs are a serious problem in
- Slugs thrive on clay soil and in damp conditions.
- Most farmers are reluctant to use pellets, but are more likely to do so after a spell of unusually wet weather.
- You might not use pellets in your garden, but how about your neighbours’ gardens? Letting your dogs free in a friend’s garden is potentially dangerous.
And a final word on rat poison
Earlier this year a friend lost his much-loved working springer spaniel to suspected rat poisoning. The dog’s death remains a mystery as my friend declined to have a post-mortem, but the symptoms — collapse, vomiting blood and difficulty breathing — indicated strongly that poison was the cause of the dog’s illness. Always be aware of the risks of poisoning to inquisitive dogs.
