He was taken straight to a vet and remained in intensive care over the weekend, but the decision was taken to euthanize him of Sunday.

An RSPCA spokesperson said: “Very sadly, despite being given round-the-clock treatment and monitored in the hope he would make some improvement, the local independent vet said there was no hope of recovery and that the kindest thing to do was put the dog to sleep to prevent further suffering.

“This was a very difficult decision which was heartbreaking for the staff caring for him, but one taken with the best welfare of the dog in mind.
