The golden retriever appeared visibly excited to see bed-ridden John on Saturday, who has been in hospital since he sustained spinal cord damage in a freak accident in early March.
Kerri-Anne wrote alongside the image that bringing Digger to the hospital was a touching moment for all to see.
“Today was the first time Digger recognised John and made us all happy. So true, pets really are therapy,” she captioned the snapshot.
Kerri-Anne’s post comes just a week after she appeared on Sunday Night in a tearful interview that outlined how tumultuous the last month has been for the iconic TV presenter and her husband.
“I still wake up every day thinking of what a nightmare it was,” she told the program. “But it’s not a nightmare. It is life.”
