The Middlesbrough-born defender, a regular for beaten play-off finalists Watford last season, became Huddersfield's seventh summer signing on Monday when he put pen to paper on a three-year contract.
"I wasn't really expecting to leave Watford, but it wasn't the perfect situation for me," Hogg told Huddersfield's official club website.
"Family-wise it wasn't ideal as my young family were living in Middlesbrough.
"In terms of the football it was really good and I felt like I would have progressed my career at Watford, so it was a very big decision that I had to make.
"My family have been great, but they are the reason why I chose to leave. I needed to look after them.
"I have two little girls and it was very tough when I had to leave them to head back down south.
"Huddersfield is the perfect fit for me and I'm looking forward to showing the fans what I am all about.
"I feel Huddersfield is an excellent place to develop my career and I'm excited by what is in store."
