Two dog owners believe they have taught their dog to speak.
Natalia and Leonid Fedorenko filmed their pet pooch Bosia appearing to say the word ''mama'' when he wanted some treats.
The two owners have claimed they haven't trained Bosia to say the word and were shocked when they heard their four-legged friend utter the word.
The pair shared the footage of their dog's trick on social media, which has since gone viral, and has also been obtained by The Mirror Online.
Natalia said: ''He is a hero. We took him when he was tiny from an animal shelter for stray dogs.
''We had been looking for a tiny dog for a long time.''
