Owner trouble. How to handle bad review and owner?

I'd like to address my last review and the only negative one I have recieved. The owner was very unreasonable and hard to deal with. I'm not sure anything would've pleased her. Her elderly, blind and deaf rescue dog who had been abused bit me while I was trying to administer some meds she had left. Mind you it took two days for me to even be able to get that close to him. The pills ( because I checked to be sure) were for a stomach bug he was clearly over. For 3 years I worked for a vet clinic in Beaumont TX. After calling my old boss and weighing all factors of this particular dogs needs and situation I decided with the advice given to me by my old boss that instead of causing more stress on a dog afraid of everything who had a normal temperature, urinating and having normal bowel movents. I decided the dogs well being and stress level outweighed me forcing a pill a vet said was uneccessary due to this given situation. I still feel i made the right decision and hope anyone that takes the time to read this and her awful review that she clearly states in her rant that when she brought the dog home he was hopping around healthy and happy. As he should've been. Mr Magoo and Ihad a great time. I shared my bed with him once he got more comfortable. HE was a total treat to have! :) I take this job very seriously and show nothing but love and kindness to your furry babies. I hope her unpleasant words don't keep me from meeting any of your puppies. I really love caring for your dog's and continuing relationships with you and your furry friends.
