Protect Your Pooch! Top 19 Toxic Plants That Are Dangerous For Dogs


Dogs are affectionate, playful, curious, and gentle creatures that love activity. They typically like to goof around the neighborhood looking for something to sniff at or even to take a bite of. Exploration of out-of-the-way places is their second nature. Hence, it is quite common to see dogs smelling or chewing some grass, garden plants, flowers, or plants in the wild. However, such behavior may lead your precious pup into danger. Indeed, some plants produce toxic reactions that can trigger serious illness and cause death. Ingestion of some particles or flowers poisonous to dogs may block their bowel, cause drooling, vomiting, mouth irritation, seizures, and coma. These are two key reasons on why eating unknown plants can harm your dog.

The two following areas are considered dangerous: your home and surroundings where dogs usually roam around. Most of the pet owners don’t even suspect how many dangerous objects can be found inside the house. When your precious pets stay inside alone all day, they may start looking interesting items to sniff at or ingest. You may say goodbye to the traditional decorative plants, rat poison, and chemicals for the yard. When the dogs are wandering around the neighborhood, they may find their vicinity appealing. So, they try to satisfy their interest looking for various strange things to taste. Dogs’ curiosity may somehow put them in danger.

The most dangerous objects for dogs that are stored at any household:

  • Rat poisons. They contain harmful chemicals that may cause bleeding, coma or death. But they look like tasty treats to dogs, so be careful;
  • Sweets, especially chocolates;
  • Pharmaceuticals for humans;
  • Cleaning agents;
  • Yard chemicals;
  • Antifreeze such as propylene glycol or ethylene glycol;
  • Decorative plants. They widely sold in flower shops without any warnings about their poisonous effects.

Try to prevent poisoning by your houseplants or garden cut flowers. Avoid buying and placing them in your house where your dog may be able to reach them. When your pet is outside the house, you may protect him in two ways: to train your pup to refrain from inappropriate sniffing and to learn what flowers are poisonous to dogs to avert a tragedy.
