1Daffodils
These easy and reliable spring-flowering bulbs add an instant splash of colour to any garden, but did you know that they can be dangerous to our furry friends? According to Tails.com, daffodils could give dogs an upset stomach, make them vomit, and make them very sleepy and wobbly.
2Azaleas
There's nothing as beautiful as an Azalea in full bloom, but they can cause nausea, vomiting and difficulty breathing if ingested by dogs. Be sure to keep these away from your canine companions this spring.
3Bluebells
"The bluebell may be a beautiful addition to your flower beds but this springtime favourite is dangerous to have around if you have a nosey puppy," say Tails.com.
"When ingested they can cause vomiting, diarrhoea, lethargy and disorientation in dogs as they contain glycosides."

4Calla Lily (plus Prairie Lily, Lily of the Valley, Peace Lily)
Most lilies (including Cala Lilys and Peace Lilys) are toxic to dogs if consumed.
"If your dog consumes a lily plant, it may cause gastrointestinal upset including vomiting, diarrhoea and abdominal pain. If your dog has got its paws on a lily and seems unwell, it's important to contact your vet for further advice."
5Tulips
Tulips contain a toxin which can irritate dogs' mouths and gastrointestinal tract, resulting in drooling, vomiting and diarrhoea. If you're planning on growing these outside this spring, ensure they are placed well away from your curious canines.
6Hyacinths
Hyacinth plants are toxic to dogs when consumed, causing vomiting, diarrhoea and drooling.
Tails.com add: "If your dog eats a large amount of the plant bulb, they may experience changes in heart rate and respiration, which then you will need to seek veterinary attention."
