Amidst the rising temperatures, pet experts are advising owners to observe the 'five second rule' to avoid paws being burned.
Mornings and evenings tend to be cooler times to go for a walk, but if it hurts your hand to touch a pavement or patio for five seconds, then it will burn your pet's paws.
Leaving a pet inside conservatories, in front of windows or inside a car during a hot spell can also be extremely dangerous.
