The footage - published in local media - shows oligarch Aleksandr Donskoy parading the Trump-style 'dog' around the city in St Petersburg.
The man, stripped to the waist and wearing a blond wig and a rubber Trump mask, snarls at passers by as Donskoy urges him: "Bite! Bite!"
As shoppers and office workers start to laugh at the spectacle, Donskoy leads the bogus hound to his car where he barks at people through the window.
Donskoy - who dubbed his stunt 'Trump, Heel!' - said: "The politician, who has given people great hope - not only in my country, but also the majority of Russians, Americans and residents of many other countries - was not able to keep his promises and follow his principles."
The footage was initially available on YouTube, but it was later taken down, with a message saying: "This video has been removed for violating YouTube's policy on harassment and bullying."
Donskoy - once the he Mayor of the northern Russian city Arkhangelsk - is known in Russia for his weird video stunts.
