Make sure your dog is protected this summer

Many popular plants found in UK gardens and wild areas can pose serious risks to our pets. Understanding these dangers is key to keeping your pet safe while they enjoy the outdoors. 

Toxic plants for pets 

  1. One of the most dangerous plants is ragwort. It's a common wildflower with bright yellow, daisy-like blooms that can cause irreversible liver damage. 
     

    Foxglove
     
  2. Another one to watch out for is foxglove. Known for its tall spikes of bell-shaped flowers, this plant contains chemicals that can cause nausea, vomiting, or severe cardiac issues in dogs. 
     
  3. Yew, often found in gardens, churchyards, and hedgerows, is highly toxic. Almost every part of this evergreen plant contains compounds that can lead to tremors, drooling, and even heart failure. 

     
    Hemlock
     
  4. Hemlock, a plant often found along riverbanks, may look like harmless wild parsley but is extremely poisonous. Just a small amount can lead to respiratory failure and death, making it one of the most dangerous plants for your pooch. 
     
  5. While often grown indoors or as ornamentals, lilies are especially dangerous to cats. Even brushing against the pollen or drinking water from a vase can cause kidney failure.   


    Rhubarb leaves
     
  6. Commonly grown in gardens and allotments, rhubarb leaves are toxic to pets due to their high oxalate content. This can lead to kidney problems and other serious symptoms.

If you suspect your dog has eaten a toxic plant  

Remove any plant material from their mouth (if safe) and call your vet immediately. It can be helpful to take a sample of the plant with you to help your vet identify the source of the toxins. 

Keeping your dog safe outdoors 

To keep your outdoor space safe, learn which plants are toxic to your pet and remove any that pose a risk. If it’s difficult to remove the plant, you may want to think about fencing areas off to keep your pet safe. 

A little prevention goes a long way in protecting your furry family members.
