“I found that a computer based scale run by Newmetrica… the same great people who gave us the Glasgow Pain Scales… is a wonderful way to get reliable quality of life scores.  You can find it here at http://www.newmetrica.com/vetmetrica-hrql/.  It generates a non-biased decision using a computer algorithum.  Answers are weighted differently so it is harder for the caregiver to subconsciously manipulate the outcome.  And they cannot go back and change their answers like they can on paper form”  Dr Mike Petty
