If you are starting to feel worried about the plants you have in your garden, don’t go and start digging them out just yet!

It is in dog’s nature to avoid plants that are poisonous to them. If your dog is bored or stressed then they may be more tempted so it is always good to keep an eye on them if they are in the garden.

To reduce risk you can pot plants out of reach or in a sectioned off area of your garden.
