Please forget your worries about salmonella Sandra, the chicken isn't in their system long in enough for any bacteria to get hold of, people have been raw feeding their dogs chicken for years and have never had a problem with it, this includes me. Some of these vets ought to get their facts straight before scaremongering and to be honest it just goes to show how little your vet actually knows about raw feeding and to be even more blunt much about the way the dogs digestive system actually works
Still at the end of the day if you would rather listen to what your vet is telling you and that raw feeding is going to probably kill your dog then I suggest you go back to feeding kibble and other commercial type foods.
Oh and great news about the biopsy
