There is plenty of evidence of this horrible Veterinarian’s behavior and actions. The DVM in question is Dr Koller at Companion Pet Clinic on Allen Road in Beaverton, Oregon. His actions have been such that he has even made national news. 

Pets Are Just ‘Property,’ So Owners Can’t Do Much When Vets Harm Them - The New York Times

We are petitioning that you pull his license and prevent him from doing this to yet another helpless animal. Veterinarians are supposed to help animals and not hurt them. I can’t even imagine the heartbreak the pet owner’s who were subjected to this deplorable behavior have gone through. Our pets are part of our family, not just some propertyto be treated without care. 

Please stop him, you have the power. 

We want to spread the word far and wide until Dr Daniel Koller DVM is stopped and put out of business of hurting animals.
