Snail bait which I presume is used to kill snails can kill dogs
Supposedly there is no chemical that can be given to cure the poison & the required treatment is taking the dog to a vet to get it's stomach pumped & then hoping that prevents it from digesting enough poison to die
The vet injected a chemical to make the dog vomit then put it to sleep then put water in it's stomach & pumped the chemical out further followed by giving activated charcoal then a liver test
