BRIAN ROSS UPDATES HIS REPORT ON MAIMED AMERICAN SOLDIERS WHO SAID THEY FEARED RETURNING HOME TO LIVES OF POVERTY BECAUSE THE GOVERNMENT WASN'T GIVING THEM THE HELP THEY NEEDED, ON ABC NEWS' "PRIMETIME LIVE," THURSDAY, JULY 7

Also: Creating Unique Extended Families -- and Some Potentially Thorny Ethical Problems -- with Embryo Adoptions

And: Helping Dogs Suffering from Serious Psychological and Behavioral Problems

ABC News Chief Investigative Correspondent Brian Ross updates his troubling October 2004 report about four American soldiers seriously wounded in Iraq who said they faced impoverishment. The men said they could no longer work in their former fields due to the injuries they sustained -- and, they said, the government had done little or nothing to help them. Ross reports that these soldiers -- one of whom was living out of his car -- and others like them returned home from war with devastating injuries and only the promise of modest military pensions. The government, these soldiers said, must devise a plan to help them and their disabled comrades survive on the home front. "Primetime Live" airs THURSDAY, JULY 7 (10:00-11:00 p.m., ET) on the ABC Television Network.

And: Greg and Cara Vest desperately wanted a child of their own after trying for five years. Bob and Susanne Gray had frozen embryos left over following their successful invitro fertilization. John Quiqones reports that an agreement enabled the Vests to give birth to the Grays' biological child and raise him as their own, resulting in a very unusual extended family. But while embryo adoption affords would-be parents like the Vests a new option, it also poses a wide range of legal and ethical dilemmas. In an update of this August 2002 report, "Primetime" again visits the Vests -- who have since been to the White House to promote embryo adoption -- and meets the newest addition to their family.

Also: Dogs are man's best friend and, as Chris Cuomo reports, they can also share man's worst anxieties. Just like people, some dogs actually suffer from serious emotional problems that lead them to misbehave, according to animal experts. In this July 2004 report, "Primetime" cameras capture dogs behaving badly in their owners' absence -- including dogs with separation anxiety and another suffering from obsessive-compulsive disorder -- and also witness the success stories of pooches who receive professional help for their problems.

DIANE SAWYER, CHRIS CUOMO, CYNTHIA McFADDEN and JOHN QUIQONES are the anchors of "Primetime Live." DAVID SLOAN is the executive producer.
