Drooling, panting, vomiting, persistent diarrhoea, burns on the mouth, lack of coordination, convulsions and coma are all signs of poisoning.
Try to determine what your pet has swallowed. The container's label may list an antidote.
Call your vet immediately. If you can't reach him, call a veterinary hospital.
Let your pet drink as much water as it wants. However, don't give it anything by mouth if it's unconscious or convulsing.
When you go to the vet, take the toxic substance and any packaging that has a label. If you don't know what the animal has swallowed, take any suspect material - loose pills, solvents, pesticides. If your pet has vomited, take a sample.
