What if the dog is poisoned by plants?

When you suspect that your dog is poisoned by plants, your first reaction should be to contact the veterinarian. Don't feed your pet, keep it warm if its temperature is very low, and cool it if it has a fever. Don't try to treat it yourself or make it vomit. If you think you are doing the right thing, you may make things worse. Find out what plants he may have ingested, and if you don't know what kind, take a sample. The best way to prevent plant-related poisoning in dogs is to avoid contact with this list as much as possible. When you walk in the forest, be sure to pay attention to what your companions are doing to avoid accidentally ingesting a potentially poisonous plant.
