A spokesman for Humberside Police said: "Ensuring your dog is kept under control when out in public is the sole responsibility of the owner and not doing so can result in injury not only to your dog but to other dogs and possibly worse.
"Failing to keep your dog under control can be a criminal offence.
"I can't comment on the specifics of this incident but fully understand the distress that it will have caused the owners of the injured dog and appreciate the frustration and concern of not being able to report the incident to prevent another animal from being injured.
"Details of this incident have been passed on to our local policing team in the area so that our officers are aware of the potentially lose (sic ) and aggressive dog when out and about and so that we can try and identify the dog's owner to prevent this happening again.
"Failing to keep your dog under control can be a criminal offence."Yes, repeating it twice in your long, boilerplate statement doesn't help. Many things can be criminal offenses, but you know what makes them so? Police getting off their arses and doing what they are paid to do - investigate before there's another victim!
This most recent attack happened at 8am and the latest victim, Ann Pedersen, has recalled the terrifying ordeal.
The "shaken" owner of the now scarred-for-life family dog, has described the moment she heard the pounding of paws behind her before a "powerful" dog clamped onto her beloved pet's neck.
"Its jaws snapped onto him and shook Bobbi like a rag doll", said Ann.
She said: "The jaws wouldn't open. The noise was awful. He was screaming in pain.
"It was terrifying and I was screaming for help."If you'd phoned 999 and said you had a gun you planned to shoot the beast with, I bet they'd turn out lickety-split then.
