POLICE in Russia are investigating a grotesque couple who adopted a dog from an animal shelter, then bludgeoned it to death before cooking and eating it.

The sickening fate of “friendly and affectionate” Nika came to light when shelter staff visited the new “respectable” owners to check on the dog on the night that the pup had finally found what he thought was a new home.

Sickened Ekaterina Valyus, a volunteer at a rescue shelter at Sakhalin, East Russia, said: “When I arrived at the house I smelled fried meat.”

Then she saw hair and blood on the concrete of the porch.

She looked around a little and noticed blood and hair staining the end of an iron scaffolding rod.

“The rest was on their stove,” she said.

Nika, who had been filmed wagging his tail and licking the twisted couple as they happily petted and adopted him earlier that day, had been mercilessly bludgeoned to death.

Sickening pictures show a big bowl of bright pink guts sat open in the couple's grimy kitchen among cooking pots.

Other nauseating images show Nika's blood splattered in the snow outside the house. There is what appears to be a puddle of urine where the poor dog wet itself as it died in agony.

There is another bucket of what appears to be browned blood and the fluid from his entrails sat in the corner of the kitchen.

A woman named Galina and her unnamed husband had taken Nika as a pet and promised to give the loving little pup a new home just hours earlier.

They initially denied that the dog had been butchered, but Galina later admitted it to police.

Dog shelter director Irina Savitskaya is demanding the couple be jailed over the disgusting incident involving the dog, who had already had a tough life on the streets before being rescued and nursed by volunteers.

She said "shameless" Galina "gave me her passport details, made a contract, took the dog, and ate her new pet that very evening.”

When the monster couple initially visited the shelter Nika had run up to them and they had appeared to fall in love with the dog.

Irina said Galina had gloated after coming clean about the horror she had inflicted on Nika.

“She has admitted that she had butchered the dog and ate it.

"She just says 'no-one will put me in jail over a dog'".
