Taking the lead: dog owners urged to keep their pets in check in the countryside

The Wildlife Trusts warn letting dogs loose in nature reserves in spring and summer can cause damage and disturbances to animals and plants

From scaring endangered birds on their nests to the mountain of excrement they produce each day, dogs with irresponsible owners are a growing problem in UK nature reserves, say conservationists, who are urging owners to keep their pets on a short lead.

The Wildlife Trusts, which operate more than 2,300 nature reserves across the country, say loose dogs are a leading cause of plant and animal disturbances in UK reserves and their waste carries diseases for wildlife, with growing evidence that the 3,000 tonnes of faeces and urine produced by dogs each day disturbs the balance of ecosystems at levels that would be illegal on farmland.
