Good morning. Sorry your pup is having an issue. I understand your worry and concern, but I’m going to pass on a few words of wisdom…until you know the results of a biopsy, you can’t make a plan for whatever lies ahead and your worry will be wasted energy. Easier said than done, I know. But our pets feed off of our energy and emotions. I remind myself of that when I start to fret about my pets, and it helps me to keep thing in perspective. I hope your dog is alright?
