Authorities in London have issued an urgent warning to dog owners after suspected poisoned meat pieces were found in two well-known city parks. According to reports, toxic chicken meat was discovered in Holland Park and Brompton Cemetery. It is suspected that the meat may have been deliberately left to harm foxes or dogs walking in these areas. A dog believed to have consumed the meat has become seriously ill, while two foxes were found dead with no visible signs of injury. Police have urged owners to keep their pets under control and not allow them to eat unknown objects during walks. Professional dog walkers said this is not the first time such incidents have occurred. Previously, poisoned toys and even tennis balls with hidden blades inside have been reported. The Metropolitan Police has called for maximum vigilance, while in the Brompton Cemetery area it is recommended that dogs be kept on a leash at all times.
