Dog walkers should keep animals on lead near ponds and rivers

Dog walkers are being urged to keep animals on a lead when walking them near rivers and ponds this summer.

The British Veterinary Association has issued a warning about an increased risk of toxic blue-green algae growth in the coming months after more than 50 sightings in lakes, ponds and rivers across the UK.

Blue-green algae is a group of bacteria that can contain dangerous toxins which can be harmful and potentially fatal to pets if ingested even in small quantities. The algae may appear as green or greenish-brown scum on the surface of water. Dogs can swallow it by drinking water from an affected lake, river or pond or while licking their fur after going for a swim.

It is possible for dogs to come into contact with the bacteria even if they don’t go into the water for a paddle, as toxic blooms are often blown to the edges of water bodies.

Cases peak in July and August, at the height of the summer season, and aren’t restricted to any one part of the UK.

Justine Shotton, President of the British Veterinary Association, said: “The majority of blooms are toxic and it is impossible to tell the difference visually, so it is better to be safe than sorry.

“It is also important to be aware of the symptoms of exposure. These commonly include vomiting, diarrhoea, drooling, disorientation, trouble breathing, seizures, and blood in faeces.”

He added: “There is currently no known antidote for the toxins, so dog owners should seek prompt veterinary treatment to tackle their effects and ensure a good chance of recovery for their pet.”

Earlier this year, a Cocker Spaniel puppy died shortly after a walk at Anton Lakes, in Hampshire.
