An XL Bully has been seized and two people have been arrested after a chihuahua puppy was mauled to death in the street, police say.
Armed police attended the incident, which took place in Skellow, a village near Doncaster, on Friday morning.
Officers believe the XL Bully escaped from a nearby home before attacking the puppy, which was being walked at the time.

“The XL Bully is believed to have escaped from a nearby property. The puppy was taken to the vets, where it has sadly had to be put to sleep.
“Firearms officers attended the scene. The XL Bully was seized and remains in police kennels.”

Chief Inspector Emma Cheney said: “As an owner you are responsible for your dog’s actions, whether that be within your home or a public place.
“If your dog causes fear or harm, it will be you, the owner who is held accountable and, in some cases, put before the courts.
“Irresponsible dog ownership is costing dog’s lives and causing serious injury to members of the public and their loved pets.
“This will not be tolerated within South Yorkshire.”
She urged dog owners to “think ahead” over the Christmas period when people are “enjoying the bank holidays with walks in parks”.
“Keep your dog under control, on a lead and if it becomes easily stressed, you may choose to walk your dog during quieter periods,” she added.
“Take the time to ensure your garden is secure and your gate locks to your dog cannot escape.”
