Dog Owners Warned: Keep Pets on Leads as Deadly Blue-Green Algae Threatens Lakes and Rivers

With British Summertime upon us, pet owners are being urged to keep dogs on leads around lakes and rivers. Why? Toxic blue-green algae — a silent killer lurking in warmer waters — is on the rise. This nasty toxin can prove fatal for your furry friends.

Veterinary Alert: Blue-Green Algae Dangers

The British Veterinary Association (BVA) has issued a stark warning. Blue-green algae, also called cyanobacteria, produces powerful toxins. Even tiny amounts pose serious health threats not only to pets, but also livestock and birds.

Dogs commonly get poisoned by:

  • Drinking contaminated water
  • Licking algae from their fur post-swim
  • Contact with algae washed up on lake or river banks

BVA President Urges Vigilance

“Many dogs love a dip to cool off in this weather, but we strongly advise keeping them on a lead near water with algal blooms,” said BVA President Justine Shotton. “Most blooms are toxic and can’t be spotted by eye, so better safe than sorry.”

“Watch for symptoms like vomiting, diarrhoea, drooling, confusion, breathing trouble, seizures, or blood in stools. They can strike within minutes or hours, causing severe liver damage—often fatal if untreated.”

There’s no antidote for blue-green algae toxins, so quick veterinary help is a must to save your pet.

Top Tips to Protect Your Dog This Summer

  • Heed water safety warnings from environment agencies or local councils.
  • Keep dogs on a lead near any water suspected of algal blooms.
  • Never let pets swim in or drink from affected lakes, ponds, or rivers.
  • Wash your dog’s coat thoroughly with fresh water after any outdoor swim.
  • Get emergency vet care immediately if you suspect algal poisoning.
  • Use the Bloomin’ Algae app to report sightings and track local outbreaks.

Stay Alert, Stay Safe

As summer heats up, so does the risk of toxic algae. Stay informed, follow expert advice, and keep your four-legged mates safe from this deadly menace.
