Dogs Trust is urging dog owners across Wales to take extra care around bodies of water this summer following concerns of an increase in blue-green algae due to the prolonged hot weather.
Blue-green algae is a type of bacteria found in lakes, ponds, and rivers, and it can be highly toxic to dogs. In periods of warm sunny weather like we are currently experiencing, the number of blue-green algae can increase, leading to potentially dangerous algal blooms.
Ingesting even small amounts of blue-green algae, either by drinking contaminated water or licking their fur after swimming, can cause serious illness in dogs. In some cases, it can prove fatal due to its effect on the liver and neurological system.
Charlie Matthias, Senior Veterinary Surgeon at Dogs Trust, said:
“As temperatures continue to soar and water levels drop, there is a potential for an increase in blue-green algae, which poses a real threat to dogs. On hot days, it can be tempting to let your dog dip in your local lake or river to cool down, but blue-green algae can make your dog very sick, and in some cases, prove fatal if ingested even in small quantities.
“We’re urging all dog owners to avoid letting their dogs swim in or drink from lakes or rivers that look green, scummy, have surface foam or have warning signs nearby. Blue-green algae is not always easy to spot, so if in doubt, don’t let your dogs swim in or drink from the water. And, if you are walking your dog near water where blue algae have formed, keep them on a lead.”
Symptoms of blue-green algae poisoning can appear within minutes and include vomiting, diarrhoea, drooling, muscle tremors, seizures, breathing difficulties, and collapse. If owners suspect their dog has been exposed, they should contact a vet immediately. While unfortunately there is no antidote for the toxins produced by the blue-green algae, if caught early enough, your vet may be able to flush the toxins from their body.
Dogs Trust advises:
- Avoid letting dogs swim in or drink from still or stagnant water during hot weather.
- Heed any warning signs around lakes, rivers, and reservoirs.
- Wash dogs thoroughly if they’ve been in contact with potentially contaminated water and immediately contact your vet for advice.
