Police-quizzed relatives of the pair about the death of a 12-day old infant mauled by a cross-breed dog said this morning it was 'nothing but a disaster.'
The 35-year-old man and 27-year-old woman were being defended after being arrested on Sunday by police investigating the death of the newborn.
They have been arrested on suspicion of gross negligence manslaughter and bailed pending further investigation.
Samantha Foulds, who appears to be a close friend of the victim, wrote on Facebook: 'I know these people well and I assure you that this is nothing but a disaster
The baby was rushed to hospital with serious injuries after the attack in the village of Woodlands on Sunday - but he tragically died a short time later.
Sally Hooley, who saw the dog being taken away by police, said, according to The Mirror: 'The dog was a big fluffy golden dog, it looked harmless at first glance. I couldn't tell you the breed but three police officers were struggling to control it to get it into the dog van.
'The dog was strong enough to be dragging three officers into the road. It's so, so sad.'
'It looked like a big fluffy harmless dog. At the end of the day the parents will never get over the loss of their child.'
It has also been revealed that the baby's 'brilliant' mother lost her partner - and father of her three children - to sepsis a year and a half ago.
A neighbour told The Sun: 'She was a brilliant mum but her whole life fell apart when he died.
'She lost everything.'
South Yorkshire Police rushed to a property in Woodlands at 3.30pm on Sunday afternoon following reports that a child had been attacked.
The baby was rushed to Doncaster Royal Infirmary with serious injuries after being bitten by the dog but died a short time later.
A man, 35, and woman, 27, have since been arrested on suspicion of gross negligence manslaughter.
Both have been bailed pending further inquires.
