Dogs of every description have been beating the heat by having a go at new sport - JettyDogs.
The canine competitors chase a ball or a favourite toy off a ramp and into a swimming pool and the dog who can leap the furthest wins.
Over 100 dogs took part in the JettyDogs display, which marked the last day of Dog Train and Behave Week at Ruxberry Farm, near Chertsey, Surrey.

With temperatures soaring to 26 degrees, the 1500 people who attended could only watch on as the dogs plunged into the ice cold water.
The British JettyDogs champion Jumping Jack Splash - who can leap a whopping 17 feet - was on hand showing his canine rivals how it's done.
There was a serious side to the event as the dogs learnt important behavioural lessons organisers say.
Spokeswoman Anna Webb said: "It's a way of promoting sensible dog ownership and showing people how to train their dogs.
"It teaches the dogs to obey orders and also lets them have fun with their owners.
"The point of JettyDogs is that anyone can do it, all you need is a dog and a ball."
The sport was recently imported from the United States where it is known as DockDogs.
