I think this is a great idea which will be so useful to both veterinarians and us, owners, if we were looking for current studies. Having had faced all kinds of health challenges in my dogs, sometimes conventional methods don't cut it.
There are times when a clinical trial may be the way to give your dog a second chance to beat their illness.
Having a database to turn to, rather than searching high and low is certainly a great help.
