A devoted dog refuses to leave her recently deceased owner's grave in New York state.

In a truly touching video filmed in Amsterdam city on November 15, 2017, Deta the dog won't leave the owner's grave, an 86-year-old for whom Deta was "a constant companion" and who had died only a couple of months previously.

"Come on Deta, let's go," encourages the dog's new owners, the 86-year-old's daughter and her husband.

At one point Deta does get up from the grave but he stops and returns.

"Deta you have to leave the cemetery, come on!" says Theresa's husband.

Theresa is reduced to tears as Deta returns to sit beside the grave. "Oh my god. Aw, it's making me cry. Deta! Deta! Deta!" she says.

Theresa later wrote online: "Deta belonged to my mother for five years and I inherited Deta on my mothers' death. My mother was 86 when she passed and rarely left her home. Deta was a constant companion. My husband and I were placing a Christmas wreath on my mother's grave on November 15.

"That stone Deta is laying next to belongs to my father and mother. You can still see the fresh dirt on my mothers' grave. She passed September 24, 2017.

"Deta (which means 'little' in Slavic) was being so quiet when we arrived, which is so out of character. My husband had to go and carry her from the grave to get her to leave."
