I just heard of something call Pet Life. It is an Immune enhancement formula. I was just wondering if anyone had tried it yet. I have been thinking about it, but I would like to talk to someone who has first. I have an Old English SheepDog and I just found out a few weeks ago that she has cancer, but because of her age & how advanced the cancer is the vet thinks it isnt treatable. Any information you have on this would be greatly appricated. Thanks, Jessica
