Jemma has seen her vet for a check-up recently, with her age, 15, he says the blindness is typical. Last time she was put to sleep for teeth cleaning, we almost lost her, so, no more surgeries for her. Her pacing seems to be anxiety now that I have read more. She has calmed down quite a bit since we returned from vacation, she had stayed with a very nice doggie sitter. My vet had suggested either anapril or senalife to calm her, but I don't like meds for myself or my pets, so I checked on-line for more natural methods. Petmeds had a couple of natural medications, one called compossure liquid that I might try, during more stressful times for her. I appreciate the feedback and encouragement.
