Visiting spring meadows with your dog might be tempting, but experts warn owners to stay clear of rapeseed fields as they can be poisonous to dogs.

According to research by the Dogs Trust, rapeseed is one of the worst toxic plants for dogs because it contains glucosinolates (a sulfur-containing compound). Dogs who ingest the plant could suffer breathing difficulties and digestive disorders, which could be caused by your dog running through the fields.

Back in June 2019, one dog suffered severe open wounds from running through a crop of rapeseed. Fields of the bright yellow flower might seem innocent enough, but they can pose health issues and cause serious allergic reactions.

"If you're in any doubt about whether your dog has ingested part of a dangerous plant, you should visit your vet as soon as possible," Sean McCormack, head vet at tails.com, previously told Country Living.

"Having the plant to hand will help your vet correctly diagnose your dog. Treatments can range from simply making your dog sick to treating them for toxicity, even surgery if necessary."

Planning to visit some flower fields this summer? Take a look at the three fields that are safe for dogs:

1. Sunflower fields

Pet owners will be pleased to know that sunflower fields are safe for dogs. As well as visiting triumphant yellow sunflower fields around the UK, you can also plant them in your garden without the worry of your dog becoming sick.

Sunflowers flourish from mid-summer to early autumn, so you're likely to start seeing them in July. Their peak bloom time only lasts around two or three weeks, so it's best to visit sunflower fields early in the season for the best chance to see them. After this, some of them may begin to lose their petals.

2. Daisy fields

Daisy fields, which usually bloom from March to October, are also safe for dogs to run through. Always check to see if flower fields are dog-friendly before visiting, as some may have rules in place.

3. Lavender fields

Right from July to September, the UK's lavender fields are in full bloom. From rolling lavender fields in Surrey to rivers of beautiful purple in Hampshire, there are plenty of places to see, and smell, the stunning sights. As well as providing a breathtaking display, these glorious blooms are also safe for dogs to explore.
