WITH the third heatwave of the summer set to hit this week a vet has issued an urgent warning to dog owners - sharing six breeds that are most at risk of overheating.
According to animal experts, 'extremely dangerous' temperatures above 28C can cause a 'life-threatening heat stroke ' for pets.

Dr Suzanne Moyes, in-house vet at Burgess Pet Care, shares her advice on which dog breeds are most at risk of overheating and how to spot the signs.
She advised: 'Heat stress in dogs can happen at temperatures over 25 degrees. And, at 30 degrees or more, the risk of heatstroke increases significantly.
'If your dog shows symptoms such as faster panting, excessive drooling, darkened gums, agitation, staggering, vomiting or diarrhoea, seek advice from a vet immediately.
'If you spot the signs of overheating, take action to cool your pet immediately and consult your vet.'
BREEDS AT RISK
Dr Moyes advised that Brachycephalic breeds of dogs have very short, flat faces, making it difficult for them to breathe.
She explained: 'In hot weather, their facial structure can make it harder for them to regulate their body temperature easily.
'While not as extreme as some other brachycephalic breeds, boxers have shorter muzzles and can therefore also struggle with the heat as they can struggle to cool down.
'Boston terriers are another breed with a pushed-in face, making them more susceptible to heatstroke.'
And it's not just dog breeds with short, flat faces that are at risk.
Those with thick, double coats such as Chow Chows, Golden retrievers, Huskies and German shepherds have thick fur that traps the heat, increasing their chance of overheating.

Dr Moyes continued: 'Senior dogs and overweight dogs are also more likely to suffer from heatstroke due to age and weight-related health issues.
'While they've not got a thick coat, surprisingly Greyhounds can be at risk as their thin coats offer little protection from the sun, causing them to overheat quickly.
'While it's important to monitor all dogs' exposure to the sun, if you have a dog breed that is more at risk it's vital to avoid prolonged time in the direct sun, ensuring they have shady spots and plenty of water.'

How hot temperature can be 'very dangerous' or fatal for dogs
VETERINARY Surgeon Kathleen Pohl, from Pet Health Club, advised that during the summer dogs should be walked early in the morning or late at night, when it's cooler.
She claimed that temperatures between 28 and 31 degrees are 'very dangerous to all dogs'.
The vet shared that whilst some breeds are more resilient, these temperatures can be life-threatening.
Therefore, Kathleen urged dog owners to avoid walking pets during these temperatures and stressed the importance of making sure they have cool places to rest.
The animal lover claimed that this is especially important for owners that have flat nose dogs such as Pugs or French bulldogs, as well as older dogs and those with health issues.
Finally, the vet shared that anything above 32 degrees is extremely dangerous for dogs.
The vet highlighted: 'At this level there's a high risk of life threatening heat stroke. Dogs can suffer from dehydration, rapid heart rate, even organ failure.'
As a result, the animal pro advised pet owners to always provide a cool spot for dogs indoors, with plenty of fresh water nearby.
Issuing an urgent warning to dog lovers, the expert concluded: 'Remember, a dog has never died from skipping a walk, but they die every year from heat stroke. Don't walk your dog in the heat.'
TIPS FOR KEEPING DOGS COOL
1. NOTE WHERE THEIR BED IS SET UP
Dr Moyes says: 'It's advisable to never keep your dogs bedding and accommodation in a conservatory, especially in warmer months.
'Conservatories typically have poor air circulation, experience high temperatures and have a lack of cool, shady spots, making the risks of heatstroke more common if pets are kept here.'
For indoor pets, such as cats and dogs, make sure they are set up in a room that stays cool - ideally on a lower floor in the house, to avoid heat rising.
Keep curtains and blinds closed during the day to block the heat out.
Keep a window open to ensure the room has good airflow or alternatively, place a fan nearby to help circulate the air.
Just make sure this isn't blowing directly onto your pet.

2. GIVE THEM WATER RICH SNACKS
It's important to make simple adjustments to your dog's routine in hot weather to help keep their body temperature regulated.
Avoid over-handling them during the hottest parts of the day, especially for older dogs.
Ice cubes can be added to water bowls and consider lining a toy with meat or fish paste before putting it in the freezer to create a cooling snack for your dog to lick.
It's important to consider that any dietary changes should be made gradually to avoid digestive upsets.

3. USE WET TOWELS
If your dog is suffering from heatstroke, you urgently need to lower their body temperature gradually.
To do this, move them to a shaded area and place wet towels near them to lower their temperature.
Just remember to never place ice on them as this can cause them to go into shock.
4. GROOM THEM
Stay on top of grooming and brush long-haired dogs daily in the summer months as their thick fur can trap the heat.
If a prolonged heatwave has set in, consider giving them a summer trim to keep them cool.
More summer risks to dogs
EXPERTS are warning pet owners to be vigilant when it comes to taking their dogs out this summer - especially when it comes to taking them to the beach.
Dr Rebecca MacMillan says it is important that dog parents are well prepped to ensure a safe trip away with their dog.
From consumption of salt water, to open holes, the Gloucestershire-based vet says there are hidden hazards to look out for.
Angela Laws, who is head of community at British pet-sitting platform TrustHousesitters, also urges pet owners to 'prioritise safety' and to 'be aware of potential hazards.'
Preventing injuries
Large holes can be hidden amongst the sand, which can cause injury if your dog trips or falls into it.
Dr Rebecca is warning pet owners, as if you are playing fetch with them, your dog might not be 'expecting a hole' as they are running, which can cause them to fall and injure themselves.
Talking to the Femail, Dr Rebecca also wanted to be mindful of other beach-going pets if you and your dog choose to dig a hole and to fill it back up before heading off.
Food for thought
Although you would never dream of drinking the water from the sea, your pets may view it as a large bowl of water for them.
However, seawater consumption is extremely dangerous for your dogs according to Dr Rebecca.
Drinking saltwater can disrupt the 'balance of electrolyte in the body and cause dehydration,' according to Rebecca.
This is also the case for sand as too much sand can cause a painful obstruction, 'which may require surgery.'
Check the temperature
Just like humans, pets can get heat stroke too.
It is most likely to occur when the body's temperature rises above 36C and hits 40C.
Dr Rebecca suggests caution when the weather outside hits 25C, and especially if it's over 27C.
She also warned pet owners to do their research on the type of breed of their dog, as some will be much more 'prone to heatstroke.'
Dr Rebecca says these dogs include flat-faced dogs like pugs and bulldogs, and large breeds with thick coats.
She urges dog parents to make sure their pet is well hydrated, try to keep them in the shade and remember to be aware of their paws burning on the ground.
Digging dangers
Dr Rebecca there could be anything from discarded BBQ's with hot coals, to broken glass or sharp objects.
She said: 'If your pooch is prone to digging, make sure you're nearby in case of any unexpected finds.'
