A GRANDMOTHER and grandson watched in horror as their pet dog was mauled to death while they were out walking in Seaton Carew.
The woman was walking near the Blue Lagoon, in Hartlepool, with her nine-year-old grandson and two dogs, an 11-year-old terrier and border collie.
The dogs were set on by a greyhound or lurcher that then ran off at around 5.10pm on Saturday, May 25.
But it returned with another two animals of the same breed and all three attacked the small terrier, causing fatal injuries.
A Cleveland Police spokeswoman said: “The lady and her grandson were left extremely shaken and distressed, witnessing their pet being killed.
“A man then approached, took the three dogs and ran away, leaving the woman and boy with the badly injured dog.
“It is believed that a man on the beach may have witnessed the attack and may be able to help police with their enquiries.
“We would urge him or anyone with information to contact police on 101.”
