People who invest in dog toys and treats for their beloved pooch probably agree that their pet dog has made them happier people.
A survey by dog charity the Retired Greyhound Trust has revealed that 97 per cent of owners say their dog has made them happier people.
Findings show that 79 per cent say their four-legged friend has transformed their lives - from meeting new people, lowering stress levels and providing companionship.
The study also found that pet dogs help with their owners' fitness levels.
Ninety three per cent said they take more exercise since getting a dog, while 34 per cent of people lost an average of 11 pounds in weight because of their increased activity levels.
Peter Laurie, chief executive of the Retired Greyhound Trust, said: "We always knew that having a greyhound, or a dog generally, as a pet brought great benefits.
"Hopefully our survey persuades others out there who want to change their lives for the better, whether it is to help with stress levels, companionship, getting active, losing a few pounds or making new friends."
