An expert has issued advice for pet owners as the UK faces another period of hot weather.

In high temperatures, dogs can easily overheat and become dehydrated, which means owners need to be on the look out for a range of signs and symptoms their pet could need help.

Temperatures up to 20°C are generally safe for most dogs, however, the higher the temperature, the higher the risk. When temperatures reach over 20°C , it’s important to exercise caution as there is a higher risk of heatstroke and dehydration.

While making sure your dog has access to clean water is a must, there is also a hidden risk associated with the over-consumption of water – water intoxication.

Sara Rowley, a senior nutritionist at Vet’s Kitchen, is encouraging dog owners to understand and recognise the signs of this condition and when it’s crucial to see a vet.

She said: “Water intoxication, albeit a rare condition, is more common during the warmer, summer months when our pets are ingesting more water than is healthy in a short space of time, through drinking, swimming or even playing in water.

“During hot spells, keeping your dog adequately hydrated is crucial, however monitoring your pooches’ water intake and making sure they don’t have an infinite source of water can avoid over-consumption.”

Symptoms of water intoxication

• Lethargy and weakness

• Nausea

• Bloating

• Vomiting- If your dog is throwing up clear liquid, this can be a sign that they’ve drunk too much water or drank it too fast. If they throw up just once, this is likely no cause for concern, but if they do so repeatedly, it can be a sign of water intoxication.

• Dilated pupils or glazed eyes

• Light gum colour (pink)

• Excessive saliva

• Lack of coordination and confusion

• Producing a lot of clear urine

It is advised to call your vet for advice immediately if you suspect your dog is displaying any of these symptoms.

However there are some steps you can take to minimise serious illness, including removing your dog from the water source, preventing them from continuing to consume water.

You can also give your dog a salty snack such as xylitol-free peanut butter or a dog-safe jerky to increase salt levels.

Sara also recommends a ‘pupsicle’ as a “healthy, hydrating and safe snack” that’s ideal for summer. These can be made my blending together their favourite fresh fruit or veg and freezing it in silicone moulds.

Vets also often recommend bananas for dogs, as they are a good source of vitamin B6, vitamin C, and potassium, and can benefit your pet’s digestive system. These can be added as an ingredient in your ‘pupsicle’.

However, if your dog prefers savoury treats, you can opt for a chicken recipe. Sara said: “Mix a cup of low-salt chicken stock, half a cup of water, and about 50g of finely shredded chicken before freezing this in a silicone mould.

“You could even use carrot as the pupsicle stick to make these chilled treats as healthy and refreshing as possible.”
