the wife and i took our 5 year old cocker spaniel to the vet today. he has lost 3pounds, has been coughing, and just not his self. they did blood work, ex-rays and found that he has pneumonia and has either a tumor pressing on his heart or is in the early stages of congestive heart failure. the pneumonia is from the fluid that is aroung his heart. he is on lasix to get rid of the fluid and other meds to help. he goes back next week for more xrays to see how he is doing. please keep us and him in your prayers, his name is stewart. poor guy, his is one of our children, it kills us to see him like this! here is a pic of our little guy.
