Symptoms of plant poisoning in dogs 

Dogs can exhibit a variety of symptoms if they ingest a toxic plant, and the severity depends on the type and amount consumed. Common signs of poisoning include vomiting, diarrhea, drooling, muscle tremors, weakness, and lack of coordination. In more severe cases, dogs may have difficulty breathing, an irregular heartbeat, seizures, and even organ failure.  

Symptoms can develop quickly and vary by toxin, so it’s crucial to act fast if you suspect your dog has eaten something harmful. If you notice any unusual behavior or signs of distress, contact your veterinarian immediately because early intervention can make all the difference. 

Tips for pet-proofing your home 

Keeping your home pet-friendly means taking steps to prevent your dog from accidentally ingesting toxic plants. Here are some simple ways to create a safer environment for your furry friend: 

• Remove toxic plants if possible: The best way to prevent plant poisoning is to eliminate the risk altogether. If you identify toxic plants in your home or yard, consider replacing them with pet-safe alternatives. 

• Set up barriers: If removing certain plants isn’t an option, use physical barriers to keep your dog away. Baby gates, decorative fencing, or plant enclosures can help prevent curious pets from getting too close. 

• Keep plants out of reach: Place houseplants on high shelves, use hanging planters, or keep them in rooms your dog doesn’t have access to. This simple step can help prevent accidental nibbling. 

• Use pet-safe deterrent sprays: Sprays like bitter apple can help deter dogs from chewing on plants. These sprays can teach your pup that plants aren’t for snacking. 

• Do your research before adding new plants: Before bringing any new plant into your home or garden, make sure it’s safe for pets. A little research can go a long way in preventing accidental poisoning. 

By taking these precautions, you can enjoy your greenery while ensuring your dog stays safe and healthy! 

What to do if your dog eats a toxic plant 

If you suspect your dog has ingested a poisonous plant, acting quickly can make all the difference.  

1. Seek veterinary care immediately: Go to an emergency vet rather than attempting home treatment, as some plants can cause severe health issues and death.  
2. Remove the plant from your dog’s reach: To prevent further ingestion, remove the plant from your dog’s reach. If possible, take a photo of the plant to help your veterinarian identify the toxin and provide the best treatment. 
3. Monitor your dog closely: Even if your dog isn’t showing symptoms right away, monitor them closely for signs of poisoning, such as vomiting, drooling, tremors, or lethargy.  
4. Save emergency numbers: Having emergency contacts saved in your phone can help you act fast in a crisis. Some helpful numbers to save are your local emergency vet, the ASPCA Poison Control Center at (888) 426-4435, and the Pet Poison Helpline at (855) 764-7661.
