Playing fetch on all fours might seem like an unusual activity for an adult, but one man who identifies as a dog says it has brought him closer to his husband. Tony McGinn, known as 'Tony Bark' to his friends, says he has been into animal role-play his entire life, and refers to himself as a 'human pup'. The 30-year-old, who was born female and is transgender, is supported by his husband and 'handler' Andrew who accompanies him to regular play dates with other role-players in their hometown of Los Angeles.
