Former first lady Barbara Bush was discharged from a Houston hospital on Saturday after being treated for six days for pneumonia.
"I cannot thank the doctors and nurses at Houston Methodist enough for making sure I got the best treatment and got back to George and our dogs as quickly as possible," the 88-year-old Bush said in a statement.
The Bush family had previously said that she was hospitalized for a respiratory ailment.
The former first lady, the wife of 41st President George H.W. Bush and the mother of 43rd President George W. Bush, is returning home just in time to celebrate a milestone: On Monday the longest-married presidential first couple will mark their 69th wedding anniversary.
