"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.

BRIEF: Are there any poisonous plants that could create these symptoms in my dog?

I have two dogs that were poisoned last week. I have been diligently trying to determine the source of the poison. If you could review the facts below, I would appreciate knowing what types of poisons could cause the symptoms: 1) dog #1 poisoned on Monday evening after being in the house for 1-2 hours; he had been outside all day in the backyard. He was not loose in the neighborhood during the day. 2) He experienced muscle tremors that escalated into seizures and some drooling. Temp. reached 107.5 3) The following Thursday (3 days later), dog #2 developed the same symptoms at 7:15 a.m. after being in our bedroom the whole night (at least 9 hrs. prior to the onset of symptoms). Drooling. I am at a loss as to what the toxin could be. Their symptoms appeared to be similar to those of snail bait poisoning, but we don't have any around our house or in our garage. I have canvassed the neighborhood and no one claims to have used snail bait yet this year. We don't have any disgruntled neighbors that we are aware of. We have cleaned out under sink chemicals in the house. We don't think it was dark chocolate, because we didn't have any around. We don't have any poisonous plants in our yard that we are aware of (I got a list and have gone through the yard.) Do you have any other ideas about what could cause the "shake and bake" symptoms? What could cause that severe a reaction hours later?


I don't have a clue what made your dogs sick. I am not a vet and tend to work with livestock more than dogs, so you should contact a vet who does treat dogs. Why do you think that the dogs were poisoned rather than just ill from some bacterial or viral disease? have you ruled out staph or salmonella food poisoning?
