Born in Dundee to a Danish father, Erentz began his football career with Dundee in 1895. At the end of the 1895–96 season, Erentz transferred to Oldham County, before signing for Newton Heath a year later, joining his brother Fred. It would be eight months, however, before Erentz made his debut for the Heathens, playing alongside his brother at full back in a 5–1 away defeat to Woolwich Arsenal on 8 January 1898. Erentz only made nine appearances for Newton Heath (six in the league and three in the FA Cup) before being transferred to Tottenham Hotspur in May 1898.
Erentz remained with Tottenham for six years, making 130 league appearances for them, as well as both the original match and the replay of the 1901 FA Cup Final against Sheffield United, helping Spurs to become the first club from outside The Football League to win the FA Cup. In December 1904, Erentz was transferred to Swindon Town, for whom he made 16 appearances before retiring through injury. He later became the trainer for London side Corinthians.
