Are you sure that he is playing with doge? Because there must have a min bet and after I saw their bet around 0.03, I do not think that any site will allow that lower number to be out on their starting bet if use doge. It should be min 1 doge for the bet or 10 doge if you want to use any bot then it may work. How much do you think 0.03 doge worth in dollars? Not even a penny
On 999Dice ( scam ) you can play with doge with a 0.00000001 bet.
On yolodice, you can bet with a minimum of 0.00000001 bet with LTC and ETH.
I don't know any other sites though.
