He said he was traumatised by the incident which as he walked three-year-old Wallie near his home in York Road, Priors Park, Tewkesbury.
According to Mr Kyle, his pet was attacked by a dog which had to be dragged away by its owner.
He said: "It was shaking my dog around like a rag doll. A couple of seconds more and he would have been dead."
He said it left Wallie with four big rips in his skin that were so severe he needed internal and external stitches.
The attack happened on Friday lunchtime.
Police officers told him they could not force the owner of the other dog, a Springer [Spaniel] -Staffordshire bull terrier, to be put down. They said this was because the incident involved two dogs and not a dog and a person.
Mr Kyle, who said he was worried that the dog might attack a child, said: "I'm gobsmacked that nothing can be done about this."
He said he would now walk his dog very early in the morning in a bid to prevent a similar incident from happening.
The owner of the cross breed, who asked not to be identified, said the call for his dog to be put down was "completely over the top".
He said he had young children and would have had his dog destroyed if it had been a risk to people. He said: "Both of us were at fault for not having our dogs on leads."
The owner said he was not aware that Mr Kyle's pet had been seriously injured and said he had been bitten by the Jack Russell when trying to separate the two animals.
Gloucestershire police spokeswoman Alexa Collicott said: "Previous decisions have been made by courts to suggest that it is in a dog's nature to wound other small animals.
"Therefore, dependent on the circumstances, it is not always a breach of legislation if a pet is wounded by a dog.
"We do sympathise with the dog's owner and understand that this must have been an upsetting incident. Officers have spoken to the owner of the offending dog, who was given words of advice."
