Royston dog event Bark in the Park, which was due to take place later today on Therfield Heath, has been cancelled due to temperatures predicted to reach the high 20s.

The wheels for the fun and informative day – organised by Royston Safer Neighbourhood Team – started turning months ago.

However, the heatwave that has seen most of the country bask in temperatures well above the 21°C average since mid June, could cause life-threatening heat stroke and other related conditions in dogs.

PCSO Penny Tomsett said: “For the dogs’ safety, this event has been cancelled due to the high temperatures expected this weekend.”

According to the Blue Cross, dogs can suffer fatal heatstroke within minutes while being in hot weather.

Their website states: “Unlike humans, dogs can’t sweat through their skin and so they rely on panting and releasing heat through their paw pads and nose to regulate their body temperature and keep cool. Imagine wearing a thick winter coat on a hot summer’s day and you’ll understand why dogs succumb to heatstroke so easily.

“Signs of heatstroke in dogs include collapse, excessive panting, and dribbling.

“If you suspect your pet is suffering from the condition, move them to a cool place, preferably with a draught, wet their coat with cool - not freezing - water, and contact your vet immediately.

“Once a dog shows signs of heatstroke the damage is often already done, which is why it’s so important to prevent it.

Their tips for keeping dogs cool are:

• Make sure your dog has access to clean water at all times, ideally a large bowl filled to the brim. Carry water and a bowl with you on walks.

• On hot days, walk your dog during the cooler parts of the day, in the early morning and late evening

• Watch your pet for signs of over-heating, including heavy panting and loss of energy. If you recognise these signs when on a walk, stop, find a shady spot and give your dog water.

• Never leave your dog (or any pet) alone in a car, even with the windows open

• Make cooling tasty treats by making ice cubes with your dog’s favourite food inside or stuff a Kong and pop it in the freezer

• Be particularly careful with short nosed dogs such as bull breeds, boxers, pugs, older dogs, and those that are overweight. These dogs can get heatstroke simply by running around.
