Dr Sean McCormack, head vet at dog food brand Tails.com, has warned that milder conditions and longer walks could lead to a surge in fleas, ticks and worms this summer. He says many owners fail to spot symptoms until infestations become established.
Ticks are a particular concern, as they can carry infections affecting both pets and humans. Dr McCormack advises a full-body check after every walk, especially if dogs have been through grass or dense vegetation. 'Catching ticks early makes a huge difference,' he said.
Fleas thrive in warmer conditions and can quickly spread through soft furnishings. 'One flea can turn into a much larger infestation because eggs fall into carpets, bedding and furniture,' Dr McCormack explained. He stressed that early prevention and regular checks are vital.
Worms are also more common in summer, as dogs explore more and drink from puddles or stagnant water. Subtle signs such as low energy, digestive upset, scooting or changes in appetite may indicate parasites. Routine worm prevention and veterinary advice are recommended.
Dr McCormack emphasised that good nutrition supports a dog's immune system but cannot prevent parasites alone. He also urged responsible use of preventative treatments, noting environmental concerns if products wash off into waterways. Simple habits like checking paws and ears, washing bedding more often, and monitoring scratching can help spot problems early.
