Is this blue green algae?

Vets have app out of hours service which i have contacted.

This is a tub used for cattle in a country park. Cattle are not currently in the field but we are on a public path. My medium dog just drank from it.

Looks like blanket weed to me.

Thank you. She drinks from puddles and rivers and I dont worry, but looking into the trough and seeing that gave me a fright.

Vets have said just to keep an eye on her.

No I don't think so - I think it's blanket weed like PP said. Blue green algae is rather faint to the naked eye to see-I'm side of you google or ask ChatGPT it will help. I took my dog swimming when a pup and there was blue algae in the water - I didn't realise until I looked down properly. She was fine. Hope your dog is ok.

No its not

No, it's not. Blue-green algae looks like faint blueish scum growing in little circles like bacterial colonies in a petri dish.

This page has some useful photos of blue green algae at the bottom, as well as commonly mistaken for. If it's got tiny leaves or comes out in green strands over a stick it's not blue-green algae.
