My Golden Retriever suddenly lost his bark. When I took him to my vet, they put a scope down his throat and found a mass growing on his larynx. I was referred to a surgical specialist who was able to remove the mass and fortunately it was not malignant. VPI was wonderful about paying me for the first vet's bill, but months went by and I didn't get anything for the surgeon's bill. I called VPI and they told me to resubmit the surgeon's bill. I was promptly paid after that.
