It's National Dog Day! Which Plants are Toxic to Dogs?
Keep Your Dog Safe Inside and Outside of the Home
Common houseplants, garden plants, weeds, and and wild plants for dog owners to avoid.
Man's best friend brings boundless joy, enthusiasm, loyalty and companionship into our lives. As we strive to create a safe and harmonious environment for our beloved dogs, it's crucial to be aware of some potential hazards that often go unnoticed – the presence of toxic plants, both inside and outside the home, that can pose serious risks to our canine companions when ingested. Read on to find out which plants dog owners should avoid.
Why is My Dog Eating My Plants?
Dogs are known to explore their surroundings through their senses, and some plants smell and taste great! This exploratory behavior might lead them to sample different plants out of curiosity. Some dogs may resort to eating plants as a response to dietary deficiencies, if their nutritional needs are not being adequately met, or to alleviate nausea and stomach upset. Dogs might also chew on plants as a means of alleviating boredom or anxiety, similar to how humans might engage in certain behaviors for comfort.
Poisonous plants can have a range of adverse effects on dogs when ingested. The specific reactions depend on the plant species and the amount consumed, but some common symptoms and consequences include:
Gastrointestinal distress - nausea, abdominal pain, vomiting, diarrhea
Neurological symptoms - seizures, tremors, disorientation
Cardiovascular problems - irregular heartbeat and changes in heart rate
Organ damage
Respiratory distress - breathing difficulties and coughing
Skin irritation, hives, itching
Lethargy
Death - in severe cases
It's important to note that some plants are only mildly toxic and might cause minor discomfort, while others can be highly poisonous and lead to serious health consequences.
These lists cover some of the most common houseplants, garden plants, and weeds known to be toxic to dogs and are not all-inclusive. If you have dogs, it's best to either avoid having these plants altogether or keep them out of reach in a place where your canine friends cannot access them. If you suspect your dog has ingested a toxic plant, seek immediate veterinary care. For more information, visit the ASPCA website or the Pet Poison Hotline.

If you believe that your animal is ill or may have ingested a poisonous substance, quick action is critical. Contact your vet or an emergency vet clinic immediately.
Many dogs spend time outside, unsupervised, in fenced-in back yards or dog runs, and certain common garden plants and weeds can pose a threat. These plants may appear harmless, yet they contain compounds that are harmful or even deadly when ingested by canines. Dog owners should be vigilant about identifying and removing such plants from their yards to ensure the safety and well-being of their canine companions.
If you need help identifying outdoor plants, using plant identification apps or local online resources specific to your region can help you. The Pl@ntNet and PictureThis apps can help with the process of identifying plants and weeds growing in your yard.
