Firth of Lorne arrived in Ehning stables in 2018. Before it was Katrin Eckermann competing the stallion. After two incidents in Aachen, Firth's owner decided to move the chestnut to Franz-Josef Dahlmann and later also Lea de Martini .

In 2014 Firth won the Longines Global Champions Tour Grand Prix in Hamburg. Also with Ehning he jumped in the spotlights.
