Hi Feebee,
17d - 7 letter "Singh or Patel, for example" (but it could also be Smith or Jones) around single letter "India" - definition is "country"
4,24 - 6 letter "danger" + 3 letter "initially vicious, aggressive, chihuahua" all reversed/turned up - definition is a Latin term meaning "danger" (danger does double duty making this a type of &Lit clue) - First word means "beware"
