Please Help Me Help My Friend. Options

[Susan-Molly'...]

My friend recently put her dog to sleep and is feeling terrible guilt. Her little boy was a rescue with a history of abuse. He was never the friendliest of dogs to strangers, but in the last few years he had started losing his sight and had become much worse, biting anyone who came near. My friend is a widow and her little dog wouldn't allow any visitors in her house. He had even started to nip at her.

Two weeks ago some old friends were coming for a visit and she took her boy to the vet to make sure it would be okay to board him while they were there. The vet told her things were only going to get worse and he recommended she have her doggy put to sleep. She went along with his advice and now is consumed with guilt. She says he wasn't really sick, just old and grouchy.

How do I help her? He was isolating her from her friends and I don't feel he was having a quality life anymore. Can anyone tell me how to comfort her?
