A Mississippi man who was looking for his lost dog alongside a creek made a disturbing discovery earlier this week when he took a second look at a glass aquarium that had been left in the woods.

Matt Williamson had found two black-and-white puppies that had been sealed inside a fish tank that was cemented shut and left in a position where it could fill with water and drown the dogs inside.

The lid was also sealed in such a way that the pups could have suffocated over time.

The man who found the dogs said they 'looked pretty desolate' and they had been 'put in here to drown'

After realizing what he'd found, Williamson alerted authorities in Hinds County, WAPT reported.

He said: 'As I got closer, I saw these eyes peering out at me and they looked pretty desolate, like they needed help,' Williamson told the station.

'They were put in here to drown.

'They wanted these puppies to drown in here.'

The dogs, who appeared to be feral and were not used to human contact because they had most likely been born in the wild, were taken to the Mississippi Animal Rescue League for treatment.

They were both put into isolation to reduce their stress levels and treated for slight fevers.

Considering their ordeal, the dogs are both in good health and they will be put up for adoption.
