AN investigation is underway after a teenager set his dog on a pet Jack Russell being walked by its owner.

The young man took a lead off his white bull breed dog before he was heard to say ‘Go get them.’

The incident happened on the Wagon Way Path in West Allotment, Newcastle, at around 7.15pm on Saturday, September 30.

RSPCA Inspector Helen Bestwick said: “A group of people with a large brindle and white bull breed type dog on a lead were walking towards them.

“The person holding the lead looked at them then took the dog off the lead and was heard to say ‘go get them’.

“The dog ran over and attacked the Jack Russell cross, who slipped her lead and managed to outrun the attacking dog.

“Her owner also got bitten in the process and ran off after his dog. Luckily, she made her way home.”

The dog needed vet treatment for puncture wounds and is recovering from what happened.

The person who set the dog on her is described as a large, heavy set white male, around six feet tall, aged between 16-18 years old.

He had a thick North-East accent and was wearing a blue jumper and dark brown camouflage-type body warmer.

The bull breed type dog had distinctive white markings and it is thought the dog may be named ‘Bowser’ or something similar.

Anyone with information is asked to call the RSPCA inspector appeal line on 0300-123-8018 and leave a message for Inspector Bestwick.
