Dr. John Church: Every family should have a dog.

60 minutes on dogs sniffing to benefit our health. Watch this story here.

An excerpt:
LIZ HAYES: And for those who have been saved by their pets, well, they'd be happy to see a good old-fashioned personal consultation. The dog sitting beside the doctor in the surgery as a way of scanning people?

GILL LACEY: It would be great fun, wouldn't it, and actually I think it would make visits to the doctors much more pleasant.

LH: The possibilities, it seems, are endless. We've all heard it a million times but has it ever been more true - the humble pooch really is man's best friend. For those mums and dads who are listening to you now what would you say to them?

DR JOHN CHURCH: You realise that they are wonderful, majestic creatures in their own right and watch their behaviour. If there is something for good or ill, if the dog is behaving in a funny way take note. Take note.

LH: It also makes a compelling argument for a family dog.

DR JC: Every family should have a dog.
