Monty Don has urged dog owners to be 'sensible' about plants which could harm their pets as he prepares to unveil his dog-friendly garden at the Chelsea Flower Show.

The horticulturalist and BBC Gardeners' World presenter has teamed up with the Royal Horticultural Society (RHS) for his first - and 'I hope my last' - garden at Chelsea filled with features for dogs including a lawn, water to wallow in and trees to cast shade.

Don defended the inclusion of plants that can be toxic to dogs in the garden, such as alliums and foxgloves, saying they were blooms he had alongside his pets without problems in his own garden.

The RHS and Radio 2 dog garden, which will not be judged, will be relocated to nearby Battersea Dogs & Cats Home after the world-famous event at the Chelsea Hospital, west London.

Don, 69, said they would remove any plants the charity did not want to have as part of the planting.
