Tried all the usual links and google with no luck, Its colours came out more once it got angry at me taking pics of it. It was spotted in north Thailand.

Thanks

Can it be a Red-necked Keelbeck Snake (Rhabdophis subminiatus; Thai: ngoo lei sam) ?

If so be careful yourselves and your dog!

I think it's a juvenile Red Necked Keel Back snake.

Snakes in Thailand

It says on this site, it does have some poison, but I believe it's a rear fanged snake which makes it far less dangerous than it's front fanged cousins. Like all snakes, best left alone and avoided.

Rhabdophis subminiatus (Red-necked Keelbeck Snake)

Thai: ngoo lei sam

Length: Up to 130 cm

These snakes are usually a lot smaller. The average length is approx. 70 cm.

Occurrence: Throughout Thailand

Behaviour/habitat:

Rhabdophis subminiatus is an adaptable snake which is at home in the woods as well as in residential areas and gardens. It prefers life near to water. The snake is active during the day. Their food is made up of frogs and fish. If threatened, they spread out their red neck area and erect themselves.

Danger: Bites can lead to severe poisoning in humans.

So these guys aren't at all good for humans? I remember seeing one in our garden in Don Muang and I thought at the time it was nothing to worry about except they are known to be aggressive.

Correctly identified. Reportedly potentially fatal. Said to be aggressive though I beg to dispute this - I've sat beside one for several minutes taking close-up photographs, and have caught several others. Have never found them to be aggressive. I have loads of them on my farm.
