Thought I would update everyone on my dogs condition. So far the blood work came back okay. He had an EKG done on Monday morning and something came back on it that is causing a slight abnormality or enlargement on the left side of his heart. They said it could be cardiovascular or his Hyroid that is causing the abnormality. They have to run another EKG, preferably after exercising and possibly x-rays. I can only hope that it is nothing too serious and can be treated. I'll update everyone once I know more.
