Vets thought a pet dog who was mauled by a group of German shepherds would not survive the attack.
Daisy, a seven-year-old Jack Russell, was set upon by the three larger dogs, suffering major brusing and bleeding, in a Finedon field next to the garden of the home belonging to her owners, David and Anne Fuller.
Vets thought the dog, which had chased a rabbit into the field, would not be able to survive the injuries it received.
And Mr and Mrs Fuller have also been left with a £650 veterinary bill following the attack last week.
But Mrs Fuller, 59, says she dreads to think what could have happened if the dogs had set upon one of her grandchildren, who often visit the house.
She is calling for potentially dangerous dogs to be muzzled when they are out in public, and wants people to take more responsibility for their animals.
The three German Shepherds were with a woman unknown to Mr and Mrs Fuller, and no action is being taken by the authorities because a dog attacking another dog is not a crime.
Mrs Fuller, who said it was wrong that action is only taken after a human is attacked and often caused serious injury, said: “You just want them to realise they should take steps to muzzle their dogs.
“My husband was in the field with the three dogs attacking our dog.
“It could have been worse – it doesn’t bear thinking about.
“We have three small grandchildren here on a regular basis.
“This attack has made us afraid to go down that part of the garden.”
She added: “We are innocent but we have been left with a massive bill and our dog nearly dead.
“I have been quite frustrated with the law as it stands. When is the law going to make people accountable?”
Mrs Fuller has also thanked Swanspool Veterinary Clinic in Wellingborough for putting Daisy back on the road to recovery.
What the law says
A spokesman for Northamptonshire Police confirmed there is no legislation specifically concerning dogs attacking other dogs.
It is against the law to allow a dog to be dangerously out of control in a public place, but a dog is only considered to be dangerously out of control if it injures a person or makes someone fear they might be injured by it.
However, a court can decide a dog is out of control if it attacks another animal.
