Here we have "Firework", and there are two reasons, one because a common name for a firework is a banger - and this card refers to bangers and mash, or sausages and potatoes. But yet another name for a sausage, especially in America, is a dog, which is where hot dogs come from.
As for our dog, he is described as being by First Light (the father) out of Liquid Fire (the mother), and he was born in July 1927. The breeder was Mr. M. Buttimer of Dunmanway, who sold him to Messrs W.C.W. Hammond and W. Grove-Williams of Cardiff. Once over in the British Isles he won forty two races including the Wimbledon Gold Cup of 1930, which was over hurdles. He was also second in that race in 1929 and 1931. Sad then that there is almost no mention of him, or any of the people connected with him online. But I will keep looking.
