Answer: Limping isn't a common symptom
of poisoning but vomiting is - but
dogs can vomit for MANY
different reasons (dietary indiscretion, kidney disease, liver disease, poisoning, intestinal
parasites, viruses like parvo, etc etc) The only way I can relate the limping to the vomiting is if she sustained some
kind of trauma (like hit by car) and may have internal injuries.
