Most exposures occur during summer months when toads are spawning. Toad venom exposure is a common problem here in Jersey. Serious poisonings are very rare in the UK.
The native toad have glands that secret venom when the toad is threatened. Exposure to the venom causes hypersalivation (excessive drooling), frothing at the mouth, vomiting and sometimes anxiety and shaking. The onset of clinical signs is within a few minutes. Typically, the dog returns from the garden showing signs as described above. Most cases respond very well to decontaminating the oral cavity by flushing with water. If symptoms persist, veterinary attention should be sought.
