thanks for the ping! I buy some stuff online for all my animals and some stuff from the vet. Rabies I wouldnt fool with, that comes from the vet, however, I have never had problems with well known heartworm medicine bought online, dogs are fine with clean bill of health.
I have known a vet that should NOT be in practise and I would NOT trust a word that she said. She messed up a simple operation and a different vet was so concerned and horrified that he treated my dog without charging me, as long s i gave him the name of the vet that screwed up.
I guess you just have to decide for yourself who to trust! : )
