Zinnias are a beautiful flower that is often overlooked. They come in all shapes, sizes and colours, with their most common being yellow. The zinnia plant can be used as an indoor or outdoor flower, making it perfect for any home or garden.

Is your dog an excessive chewer?

Should dogs know not to eat zinnias?

Yes, dogs are a lot smarter than people give them credit! Dogs can use their sense of smell to tell if something is poisonous. This has helped many dogs avoid danger in the wild and at home too. However, not all dogs have this skill, and some will still eat flowers in your garden even when they know better. But, at least with zinnias, you don’t need to worry about your dog eating a couple now and then, as they are not poisonous to dogs in moderation.
