We all have heard of service dogs that could spot their owners' illness. In UK, a rabbit did the job normally done by a service dog. From the photos, it looks like a Flemish Giant but in UK, it's probably called the Continental Giant. On BBC website, the report says,
"Simon Steggall, 42, of Warboys in Cambridgeshire, said Dory, a one-and-a-half stone rabbit, jumped on his chest and thumped furiously when he passed out while watching television.
Dory's odd behaviour caught the attention of Mr Steggall's wife, Victoria, 32, an ambulance driver.
When her attempts to bring him round failed, she rang 999 for paramedics for help.
"I work for the ambulance service and I'm embarrassed that the rabbit spotted it before I did," Mrs Steggall said.
"Although she is a house rabbit, she's not allowed on the furniture.
"The rabbit came up on my lap and started tapping and digging at my chest and looking at my face.
"That caught Victoria's attention and she realised something was wrong."
Mr. Steggall, a diabetic since childhood who has to inject insulin four times each day, said he did not get any warning when he was about to be unwell.
"One moment I am vertical and next minute I am waking up with a paramedic. It's like a flick of a switch."
