VETS are warning pet owners to be cautious of bacteria found in lakes that could seriously harm their dogs.

PDSA Vet Nurse Nina Downing said blue-green algae is most prevalent in still or stagnant water during summer.

“This particular type of bacteria is highly poisonous to animals, and can sadly be fatal, or result in long-term health problems for those that survive," she said.

“Dogs are particularly at risk, as they are more likely to drink from ponds while out on a walk, or groom themselves after swimming in affected water.

"However, the more aware we are of the potential dangers, the better we can protect our precious four-legged friends.

"Symptoms of blue-green algae poisoning can occur very quickly within 15 minutes to one hour of exposure and even a small amount can be lethal to a dog, so it’s important to act quickly and contact your vet immediately.

"Signs to look out for include vomiting, twitching, seizures, diarrhoea, increased thirst, drooling, breathing difficulties, or a collapse.”

Vets are advising dog owners to keep a close eye on their pets when walking them near water and ensure that they do not drink from any lakes or ponds.
